Answer:

A molecular compound is composed of two or more non metallic elements that are held together by covalent bonds.

The two major characteristics of molecular compounds are;

1.) They are held by covalent bonds

2.) They generally have poor conductivity

Explanation:

A molecular compound is one where two or more molecules come together to form a compound. Unlike ionic compounds that combine by the transfer of electrons, molecular compounds form by sharing electrons. The pairing of the electrons is what holds the molecules together and is known as covalent bonding.

A molecular compound has various characteristics, some of which are;

- Generally low melting and boiling points

- Soft solid forms

- Low enthalpy of fusion and vaporization.

But the two major characteristics of molecular compounds are;

1.) They are held together by covalent bonds.

The elements in a molecular compound share their electrons by having their atoms bond chemically to each other.

2.) They generally have poor conductivity

Molecular compounds do not conduct electricity and heat properly. Because they are formed by sharing electrons, they usually have no free electrons left to conduct electricity.

Answer:

For each molecule of glucose produced: 6 water water molecules are oxidized, and come to be the supply of electrons for carbon dioxide reduction. 6 molecules of carbon dioxide are required, one for every carbon atom in glucose. 6 molecules of oxygen are produced as a with the aid of made from water oxidation.

The law of reflection states that the angle of incidence and the angle of reflection are always equal.

Answer:

They need to use energy from other tress to survive so that they can do basic functions, like absorbing nutrients from the ground, and growing back leaves. They don't have chlorophyll, so they need that energy to do the functions I mentioned above.

Explanation: Hope this helps!

Answer:

Trees need chlorophyll to make energy. Because albino trees don’t have chlorophyll, they can’t create their own energy. So, they must take energy from other trees to survive.

Answer:

Both graduated cylinders and beakers are pieces of laboratory glassware that have a specific function. Graduated cylinders typically are more accurate at reading the volumes of the liquid inside. Beakers are better for stirring and mixing liquids.

Flasks are notable for their unique shape: a rounded vessel and a cylindrical neck. The main differing characteristic between a flask and a beaker is that beakers have straight sides, rather than slanted sides like a flask. Beakers are mainly for measuring and transporting liquids from one site to the next.

Answer: Its an element or compound that loses (or "donates") an electron to an electron recipient (oxidizing agent) in a redox chemical reaction.

CREDIT: Wikipedia

Answer:A reducing agent typically is in one of its lower possible oxidation states and is known as the electron donor.

Example: Examples of reducing agents include the earth metals, formic acid, oxalic acid, and sulfite compounds.

Answer:

[tex]P_2=1971.2torr[/tex]

Explanation:

Hello there!

In this case, by recalling the Gay-Lussac's gas law, as a directly proportional relationship between pressure and temperature, we can write:

[tex]\frac{P_2}{T_2} =\frac{P_1}{T_1}[/tex]

Thus, by solving for the required final pressure, in atmospheres first, we solve for P2 as follows:

[tex]P_2 =\frac{P_1T_2}{T_1}\\\\P_2=\frac{2.25atm*317K}{275K}\\\\P_2=2.59atm[/tex]

Which in Torricelli is:

[tex]P_2=2.59atm *\frac{760torr}{1atm}\\\\P_2=1971.2torr[/tex]

Answer:

The rollercoaster has the lowest kinetic energy at the top of the hill.

The rollercaoster has the highest kinetic energy at the bottom of the hill.

Explanation:

The kinetic energy of any solid body in motion is usually computed using this formula:

K.E = [tex]\frac{1}{2}mv^2[/tex]

From this, we can see that it varies based on two major parameters - The mass of the moving object and the velocity of the moving object.

We can assume that the mass of the rollercoaster is constant since no one gets off and it does not shrink in its size during the ride.

This means that the variations in the K.E are mainly coming from its velocity.

At the top of the hill, the rollercoaster is moving at its slowest pace. hence, it has the lowest kinetic energy at the top of the hill.

However, at the bottom of the hill, the rollercoaster is moving its fastest, hence it has the highest kinetic energy at the bottom of the hill.

answer

Avogadro's law states that, at constant temperature and pressure, the volume of a gas is directly proportional to the number of moles present. In other words, equal volumes of gases at the same pressure and temperature contain the same number of molecules - this is true regardless of their physical properties or chemical nature.

This number of molecules is

6.022

⋅

10

23

and is known as Avogadro's number,

N

.

Matematically, Avogadro's law can be written like this

, or, better yet,

Avogadro's law, as well as Boyle's law and Charles' law, are special cases of the ideal gas law,

. If temperature and pressure are kept constant, and knowing that

Answer: 1. 20.0 grams

2. 0.272 moles

3. B) Mass --> Moles --> Volume

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

To calculate the number of moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given molecules}}{\text{Avogadros number}}[/tex] or

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex] or  

Putting in the values we get:

1. [tex]\text{Number of moles of} Cl_2=\frac{1.7\times 10^{23}}{6.023\times 10^{23}}=0.282moles[/tex]

Mass of [tex]Cl_2=moles\times {\text {Molar mass}}=0.282mol\times 71g/mol=20.0g[/tex]

2. [tex]\text{Number of moles of NaCl}=\frac{3.28\times 10^{23}}{2\times 6.023\times 10^{23}}=0.272moles[/tex]

3. [tex]\text{Number of moles of water}=\frac{26g}{18g/mol}=1.44moles[/tex]

Volume of water =[tex]moles\times {\text {Molar volume}}=1.44mol\times 22.4L/mol=32.4L[/tex]
