Answer:

gas to solid

Explanation:

Exothermic means the release of heat. Any transformation from a less ordered to a more ordered state releases energy. This is represented by the change of a liquid to solid, gas to liquid, or gas to solid. Vise versa endothermic is the transformation from a more ordered state to a less ordered state represented by solid to liquid, liquid to gas, and solid to gas.

What is the total pressure exerted by a mixture of 48.0 grams of CH4 and 56.0 grams of
Oksi-84 [34.3K]

The pressure of the gas is obtained as 48 atm.

<h3>What is the total pressure?</h3>

Now we know that;

Number of moles of CH4 = 48.0 grams /16 g/mol = 3 moles

Number of moles of H2 =  56.0 grams/2 g/mol = 28 moles

Total number of moles present = 3 moles + 28 moles = 31 moles

Using;

PV =nRT

P = total pressure

V = total volume

n = total number of moles

R = gas constant

T = temperature

P = nRT/V

P = 31 * 0.082 * 286/15

P = 48 atm
