in terms of bonds what would the molecule C6H12 be classified as

Answer:

Protons and neutrons have almost the same mass and are both located in the nucleus of the atom

Answer:

Protons and neutrons have almost the same mass and are both located in the nucleus of the atom. Protons are charged particles. Neutrons are neutral particles. ... The positive charge of the protons in the nucleus is balanced by the negative charge of the electrons.

Bohr describe the arrangement of particles within an atom by: O D. Protons and neutrons form the nucleus of the atom, with electrons orbiting it.

This hypothesis states that the atom's core is a small, compact, positively charged nucleus. Protons which have a positive charge and neutrons which are neutral are both found in the nucleus.

Specific energy levels or electron shells are where the negatively charged electrons orbit the nucleus. Due to the quantization of these energy levels, only a limited number of discrete energy states are accessible to electrons.

Therefore the correct option is D.

The two terms apply to oceanic crust rather than continental crust C. Denser and D. Younger in age

Oceanic Crust Oceanic crust, extending 5-10 kilometers (3-6 kilometers) beneath the ocean floor, is mostly composed of different types of basalts. Geologists often refer to the rocks of the oceanic crust as “sima.” Sima stands for silicate and magnesium, the most abundant minerals in oceanic crust.

Oceanic crust is thin (6 km thick) and dense (about 3.3 g/cm), consisting of basalt, gabbro, and peridotite. They include oceanic sediments (e.g. radiolarites, turbidites) and oceanic crust (e.g. basalt, pillow lava).

Answer:

727.7 torr

Explanation:

Since the gas was collected over water, it is likely to be saturated with water vapour and the total pressure is given as;

Ptotal = Pgas + Pwater

From the question;

Ptotal = 751 torr

Pgas = ?

Pwater = 23.8 torr

Making Pgas subject of equation, we have;

Pgas = Ptotal - Pwater

Pgas = 751 torr - 23.8 torr

Pgas = 727.7 torr

Answer:

Ionization energy decreases from top to bottom in groups as the size of the atom becomes larger. For example, the first ionization energy of hydrogen is 1310 kJ mol⁻¹. The first ionization energy of lithium is 519 kJ mol⁻¹. Because lithium is a bigger atom and has more protons than hydrogen, its ionization energy is lower. So, in groups, the lower the ionization energy, the larger the atom and the more protons/electrons it has.

Ionization energy also increases from left to right across a period. The more protons in the nucleus, the greater the attraction between the nucleus and the electrons, which makes it more difficult to remove electrons. Helium has an ionization energy of 2370 kJ mol⁻¹ while hydrogen has an ionization energy of 1310 kJ mol⁻¹ because helium's nucleus has 2 protons attracting electrons instead of 1 like hydrogen. So for periods, the higher the ionization energy, the smaller the atom and the more protons/electrons it has.

Ionization energy is the energy required to remove an electron from its orbital around an atom. It increases across a period because the number of protons in the nucleus increases. This creates a stronger attraction between the nucleus and electrons, causing the electrons to be held tighter by the higher nuclear charge. Because the electrons are more difficult to remove, more energy is required which causes the ionization energy to be higher. So for periods, the more electrons the atom has, the higher the ionization energy. Ionization energy decreases down a group because the first electron removed is farther from the nucleus as the number of protons increases. Being farther away from the nucleus makes it easier for the electron to be pulled off as it is more loosely bounded, so less energy is required to remove the electron which causes the ionization energy to be lower. So for groups, the more electrons the atom has, the lower the ionization energy.

Groups are vertical columns going down on the periodic table. If you look at a periodic table, across the top, you will see the numbers 1-18. Those numbers signify the 18 groups of the periodic table. Iodine is a halogen so it is under Group 17 to the far right of the periodic table.

Answer:

it would decrease [h+]

Explanation:

 This is due to  neutralization If a base is added to an acidic solution, the solution becomes less acidic and its position changes to the middle of the pH scale.

hope this helps

Answer:

Raise the pH

decrease [H+]

Explanation:

=> Adding base would raise the pH (Bases have more pH and Acids have less pH)

=> Adding base would decrease the concentration of [H+] ions as it contains hydroxyl ions which neutralized with H+ ions so as a result the concentration of [H+] ions decreases.

Answer:

One factor that affects that affects the direction of the current is the direction of motion of the wire

Explanation:

According to Fleming's right hand rule when a conductive wire which is within a circuit is moved through a magnetic field, due to Faraday's law of electromagnetic induction an electric current is induced in the wire such that the direction of motion of the wire, the direction of the magnetic field and the direction of the electric current are perpendicular to each other such that if the right hand has the thumb middle finger and the index finger held perpendicular to each other

The motion of the wire being in the direction of the wire

The first or index finger points in the direction of the magnetic field

The middle finger points in the direction of the induced electric current

Therefore, the direction of the the current depends on the direction of motion of the wire.

The nuclei of atoms become unstable when the repelling forces of the protons cannot be balanced by the number of neutrons in the nucleus. It then re-arranges itself randomly to a more stable configuration by emitting any of a series of particles. During radioactive decay, an atom does not collapse.

Since an atom is mostly empty space - that is it’s nucleus is relatively distant from the electron shells so, in the presence of extreme forces such as gravity inthe collapse of a large star, the inward pressures on the atom overcome the natural balance of the atomic structure and the ‘empty space’ disappears as nuclei are mashed together by the intense pressures and a neutron star is formed. Under even more external pressure, even the neutron star can collapse to form a black hole.

Answer:

91.4%

Explanation:

Potassium hydrogen tartrate, KHT, reacts with KOH as follows.

KHT + KOH → H₂O + K₂T

where 1 mole of acid (KHT) reacts per mole o base (KOH), -That is acid/base ratio 1:1

The endpoint of a titration is the point in which moles of KOH = moles of KHT, you can see this endpoint with an indicator or doing a potentiometric titration.

As the endpoint requires 21.58mL = 0.02158L of a 0.1125M KOH, moles of KOH = moles of KHT are:

0.02158L × (0.1125mol / L) = 2.428x10⁻³ moles of KOH = moles of KHT

To convert these moles to grams you use molar mass of KHT (188.177g/mol):

2.428x10⁻³ moles of KHT × (188.177g / mol) = 0.457g of KHT are in the sample.

As you add 0.500g of sample, percentage of KHT in the sample is:

(0.457g / 0.500g) × 100 =

-That is the purity of the sample-

Explanation: In order for cellular vitality to develop, it is necessary for it to be in energetic balance with the environment, that is, to give and receive energy with the environment that surrounds it through endothermic or exothermic reactions. That is why the development of life is considered a system that constantly exchanges with the environment. In turn, that the cell unit maintains a balance with the environment causes homeostasis to occur among the whole organism.

Answer:

D. Pressure

Explanation:

The rate of a reaction is defined as the speed at which the reactants are converted into products. Factors influencing the rate of a reaction are concentration, catalyst, temperature, surface area,  and pressure, etc.

In case of the reaction rate of gases, pressure will only have its affect as pressure do not have any influence on solid and liquid.

While concentration, surface area and catalyst influence all reaction rates including solid, liquids and gases.

Hence, the correct option is (d) pressure.

Answer:

Option C. 2000 cm³.

Explanation:

We'll begin by calculating the number of mole in 2 g of Mg. This is illustrated below:

Molar mass of Mg = 24 g/mol

Mass of Mg = 2 g

Mole of Mg =?

Mole = mass /Molar mass

Mole of Mg = 2/24

Mole of Mg = 8.33×10¯² mole.

Next, we shall determine the number of mole of H2 produced from the reaction. This is illustrated below:

Mg(s) + 2H^+ (aq) —› Mg^2+(aq) + H2 (g)

From the balanced equation above,

1 mole of Mg reacted to produce 1 mole of H2.

Therefore, 8.33×10¯² mole of Mg will also produce 8.33×10¯² mole of H2.

Finally, we shall determine the volume of H2 produced. This is illustrated below:

1 mole of H2 occupy 24000 cm³ at room temperature and pressure.

Therefore, 8.33×10¯² mole of H2 will occupy = 8.33×10¯² x 24000 ≈ 2000 cm³ at room temperature and pressure.

Therefore, 2000 cm³ of H2 were obtained from the reaction.

Answer:

The most important first realization is to find out if the patients are deceased and their bodies are acting under an outside volition such as a virus reanimating the body through the use of the brain stem. If they are still living then they are what would be called infected if dead they are the undead naturally enough. Keep them contained as best you can but knowing scientists they will get free. When facing an infected they can die to any injuries that a normal human can they just won't react to pain so don't shoot for the head blast that thing in the chest then hit it in the head while it's down. Forget hand to hand combat or most close-ranged weapons unless absolutely necessary because close contact means exposure to fluids from the zombie they don't have to bite you to turn you. There is so much more to be said about this I recommend picking up the ZAS zombie survival book I recently got it and have not yet finished it but have learned a great deal.  

Explanation:

Yes I fully understand this is not real and I simply felt like answering in a detailed manner for fun and that book is a serious recommendation.

Answer:

The most significant first acknowledgment is to see whether the patients are expired and their bodies are acting under an outside volition, for example, an infection vivifying the body using the cerebrum stem. On the off chance that they are as yet living, at that point they are what might be called tainted if dead they are the undead normally enough. Keep them contained as well as can be expected however knowing researchers they will get free. When confronting a tainted they can bite the dust to any wounds that an ordinary human can they just won't respond to torment so don't go for the head shoot that thing in the chest at that point hit it in the head while it's down. Disregard hand to hand battle or most close-extended weapons except if completely fundamental since close contact implies introduction to liquids from the zombie they don't need to nibble you to turn you. There is quite a lot more to be said about this I suggest getting the ZAS zombie endurance book I as of late got it and have not yet completed it yet have taken in a lot.

Answer:

1) Ba(OH)₂

2) The correct option is a) they conduct electricity.

Explanation:

To deduce the formula of Barium hydroxide, we have to go to the periodic table and look for the Barium (Ba), which is in group 2 and has an ionic charge of 2+. Hydroxides are not an element that is present in the periodic table is the combination of Oxygen and Hydrogen (OH), and its ionic charge is 1-.

To name this substance, we write the elements that form it, which are Ba OH, then we see the ionic charges that they have, Ba2+ OH 1- and we change these charges giving the 2+ to the OH and the 1- to the Ba. It would look Ba OH₂; we do not write the 1, and as there is a 2, the OH, has to be between brackets so that the final formula is Ba(OH)₂. What we did is balancing the charges of the elements. In other words, we need 2 OH for every Ba. Hydroxides give an electron to balance the Ba ionic charge.

Barium Hydroxide is an ionic compound because ionic compounds are formed by a metal (Ba) and a nonmetal element (OH), ionic compounds are charged, so when they are in an aqueous solution they conduct electricity because their ions move freely in the solution.
