Explanation:densidad es masa entre volumen

Answer:

0.25 g/cm³

Step-by-step explanation:

As we know

The density is given by

Density = Mass / Volume

Putting the values

Density = 5g / 20 cm³

Density = 0.25 g/cm³

How does the suns energy contribute to the movement of water in the water cycle?

Answers

Answer:Evaporation

Explanation:

The suns heat speeds the movement of water molecules, until the molecules move fast enough that they jolt out the surface of the water individually. Overtime the water gradually evaporates into water vapor.

What kind of molecule can experience hydrogen bonding?
A. A nonpolar molecule containing a hydrogen atom
B. A molecule with hydrogen bonded to any nonmetal
C. A molecule with hydrogen bonded to O, N, or F
D. Any polar molecule containing a hydrogen atom

Answers

Answer:

Answer is C

Explanation:

C - A molecule with hydrogen bonded to O, N, or F

A molecule with hydrogen bonded to O, N, or F can experience hydrogen bonding. Therefore, the correct option is option C.

A hydrogen atom is attracted to another electronegative atom in a neighbouring molecule when it is connected to a strongly electronegative atom (O, N, or F). This attraction is more powerful than the usual dipole-dipole interactions between polar molecules.

The enormous electronegativity differential between hydrogen and the highly electronegative atom causes hydrogen bonding. The electronegative atom attracts the shared electrons in the covalent link, causing the hydrogen atom to gain a partial positive charge.

what would happen if the
attractive forces between all of the particles
of matter on Earth were equal?

Answers

Either everything would solid (strong attractive force), liquid or gas (weaker attractive force). Everything would be the same matter

The magnitude of attractive forces between particles that compose matter determine the state of matter. Hence, if all particles of matter on earth have equal attractive forces, only a single state of matter (solid, liquid or gas) will exist on earth.

Matter exists in three states;

SolidLiquidGas

In solids, there exists the greatest magnitude of attractive forces between particles.

There are weaker inter-molecular attractive forces between liquid particles. However, inter molecular attractive  forces are almost non-existent in gases.

The reason for the existence of different states of matter on earth is difference in magnitude of inter molecular attractive forces in each state of matter.

If all particles of matter possess equal attractive forces, only one state of matter will be found on earth; either solid, liquid or gas.

A gas is produced when 25 g of substance X is mixed into 60 g of solution Z in a beaker. The mass of the solution in the beaker after the reaction is 75 g. What is the mass of the gas released?
(X + Z -> gas + solution)

Answers

mass of the gas = 10 g

Further explanation

The law of conservation of mass :

In a closed / isolated system, the total mass of the substance before the reaction will be equal to the total mass of the reaction product.

Reaction

[tex]\tt X+Z\rightarrow gas+solution[/tex]

mass before reaction=mass after reaction

[tex]\tt 25+60=gas+75\\\\gas=25+60-75=10~g[/tex]

How much energy would be required to heat 10.0 g of water at 0 degrees C to 100 degrees C,and change it into steam at 100 degrees C

Answers

Answer:

Q = 4180 J

Explanation:

Given data:

Mass of water = 10.0 g

Initial temperature = 0°C

Final temperature = 100°C

Heat required = ?

Solution:

Specific heat capacity of water is 4.18 j/g.°C.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 100°C - 0°C

ΔT = 100°C

Q = 10.0 g ×4.18 j/g.°C × 100°C

Q = 4180 J

In what way do the atoms in the same row of the Periodic Table increase from left to right?

Answers

Answer:

As you move from left to right, the nucleus gains protons. This increases the positive charge of the nucleus and its attractive force on the electrons. At the same time, electrons are added to the atoms as you move from left to right across a period.

What is the relishing hip between the chemical energy provided by the battery and the electrical energy produced according to the law of conservation of energy

Answers

Answer:

Equal

Explanation:

Energy is always conserved in the nature and it is an universal law. According to the law conservation of energy, it is said that energy can never be created out of something and we can never destroy and vanish any energy in any form. Energy in any form can only be transformed to some other forms of energy. This is known as conversion of energy.

In the context, the chemical energy that is produced by the battery and the electrical energy produced should be equal.

A photon has an energy of 2.34x10-28 J. What is its frequency?

Answers

Answer:

f = 3.53×10⁵ s⁻¹

Explanation:

Given data:

Energy of photon = 2.34×10⁻²⁸ J

Frequency = ?

Solution:

h = 6.63 ×10⁻³⁴

Formula:

E = hf

2.34×10⁻²⁸ J = 6.63 ×10⁻³⁴ × f

f = 2.34×10⁻²⁸ J /  6.63 ×10⁻³⁴ Js

f = 0.353×10⁶ s⁻¹

f = 3.53×10⁵ s⁻¹

what are the similarities and differences between the crocodile , sheep , and gorilla digestive system?​

Answers

Answer: Crocodile is a reptile whereas sheep and gorilla are the mammals.

Explanation:

Crocodile, sheep, and gorilla have alimentary canal in their digestive system. The urea is the common excretory waste.

Mouth is typically large in case of crocodile and comparatively small in sheep and gorilla.

In crocodile more sharp teeth are present as compared to sheep and gorilla for mastication of food and capturing the prey like fish or large animals like zebra.

The crocodile palate is more stronger than sheep and gorilla because it enable it to chew the bones of the prey.

Devin had a bucket of shredded metals the metals consist of aluminum steel and copper he tried sorting the mixture by running it through a filter but this did not sort the mixture into separate components what can devin conclude

Answers

Answer:

Devin's problem can be solved by exploiting the activity series of metals.

Explanation:

This determines what metals are more reactive and would be readily displaced in a reaction.

Seeing as they are both metals scraps of similar sizes, filtration isn't a solution.  But since Copper is lower on the activity series than Aluminium, adding an acidic solution (say tetraoxosulphate VI solution) to the mixture, would have aluminium in solution and Cu as residue which can then be filtered off.

8. The following system contains 20.0 psi each of gases A and B in the end bulbs with an evacuated bulb in the centre. Both stopcocks are opened at once. What is the new overall pressure in the system?


I literally have no idea how to even start this, I know that the answer is 13.3 psi, but I don't have any clue why or how to get there.

Answers

Answer:

13.3

Explanation:

Before opening the stopcocks you have 40psi in total.

After that, those 40psi will be divided into 3bulbs, so 40/3=13.3psi for the system.

how to determine whether a liquid is pure water or not besides boiling the liquid?

Answers

Answer:

Explanation:

Aside the boiling point of water, another colligative property that can be used to identify pure water (or not) is the freezing point. Water freezes at 0 °C, but with the presence of impurities, there is a freezing point depression of the water. Thus, if the water is not pure, the liquid could freeze at a temperature lower than 0 °C (with a negative sign like -8 °C).

Down a group, the electron shielding tends to________

Answers

Answer:

Explanation The number of energy levels (n) increases, and so does the distance between the nucleus and the outermost orbital. The increased distance and the increased shielding weaken the nuclear attraction, and so an atom can't attract electrons as strongly.

As free people, we must face a choice between two types of discipline. One is the self-discipline that is still open to us-the kind which free people and free nations exercise when they select the executives, lawmakers, and Judges who will govern them and assure their protection and well-being. The second is a cold blooded, ill-Intentioned, godless form of discipline that may be thrust upon us by strangers-the discipline of force, terrorism, suspicion, and intimidation-the discipline used in China and the former Soviet Republic.
