Answer: Magnesium Mg

Explanation:

Oxidization is the process by which a substance either gains oxygen or losses electrons.

The chemical reaction of the above is denoted by,

Mg(s) + 2HCl(aq) -----> MgCl2(aq) + H2(g)

Mg went from a 0 to a +2 state which would mean that it lost electrons.

It was therefore oxidized.

Answer:

27.7 grams of Li

0.140 moles of Co

0.158 moles of K

59.9 grams of As

8.00x10⁻⁹ moles of U

142.8 moles of H

0.0199 moles of O

0.666 moles of Pb

Explanation:

Mass / Molar mass = Mol

Mol . Molar mass = Mass

3.99 m . 6.94 g/m = 27.7 grams of Li

8.28 g / 58.93 g/m = 0.140 moles of Co

6.17 g / 39.1 g/m = 0.158 moles of K

0.8 mol . 74.92 g/m = 59.9 grams of As

6.02x10²³ (NA) particles are contained in 1 mol

6.02x10²³ are contained in 1 mol U____ 1 mol  H ____ 1 mol O ___ 1 mol Pb

4.82x10¹⁵ atoms U  ____ 4.82x10¹⁵/ 6.02x10²³ = 8.00x10⁻⁹ moles of U

8.60x10²⁵atoms H  ____ 8.60x10²⁵ / 6.02x10²³  = 142.8 moles of H

1.20x10²² atoms O  ____ 1.20x10²² / 6.02x10²³ = 0.0199 moles of O

4.01x10²³ atoms Pb ____ 4.01x10²³ / 6.02x10²³ = 0.666 moles of Pb

4P + 502 → 2P20x
Thepotemich [5.8K]

Answer:

5

Explanation:

According to the Law of Conservation of Matter, the mass of the products in a chemical reaction must equal the mass of the reactants.

5O2 = 10 Oxygen atoms

In 2POx there must be 10 Oxygen atoms too. => x = 5

...

Hope it can help you.

5. What are the relative rates of diffusion for methane, CH, and oxygen, O2? If O2 la travels 1.00 m in a certain amount of time
11Alexandr11 [23.1K]

Answer:

The relative rates of diffusion for methane and oxygen is 1.4142.

Methane gas will be able to travel 1.4142 meter in the same conditions.

Explanation:

To calculate the rate of diffusion of gas, we use Graham's Law.

This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. Mathematically written as:

\text{Rate of diffusion}\propto \frac{1}{\sqrt{\text{Molar mass of the gas}}}

We are given:

Molar mass of methane gas, m = 16 g/mol

Molar mass of oxygen gas,m' = 32 g/mol

By taking their ratio, we get:

\frac{d_{CH_4}}{d_{O_2}}=\sqrt{\frac{m'}{m}}

\frac{d_{CH_4}}{d_{O_2}}=\sqrt{\frac{32}{16}}=1.4142

The relative rates of diffusion for methane and oxygen is 1.4142.

If oxygen gas travels 1 meters in time t.

Rate of diffusion of oxygen =d_{O_2}=\frac{1 m}{t}

If methane gas travels travels in y meters in time t.

Rate of diffusion of methane=d_{CH_4}=\frac{y }{t}

\frac{d_{CH_4}}{d_{O_2}}=\frac{\frac{y }{t}}{\frac{1 m}{t}}=1.4142

y = 1.4142 m

Methane gas will be able to travel 1.4142 meter in the same conditions.

Why is it necessary for a molecule to absorb energy in order to break a chemical compound
nasty-shy [4]

When a chemical reaction occurs, molecular bonds are broken and other bonds are formed to make different molecules.

For example, the bonds of two water molecules are broken to form hydrogen and oxygen. Energy is always required to break a bond. Hope this helps you!
