The total pressure of a mixture of hydrogen, oxygen, and methane is 96.4 kPa. The partial pressures of hydrogen and oxygen are 13.5 kPa and 29.3 kPa respectively. What is the partial pressure of methane?

A. 139.2 kPa
B. 53.6 kPa
C. 82.9 kPa
D. 42.8 kPa

53.7kPa

Explanation:

Given parameters:

Total pressure of the mixture  = 96.4kPa

partial pressure of hydrogen  = 13.4kPa

partial pressure of oxygen  = 29.3kPa

Unknown:

partial pressure of methane  = ?

Solution:

The total pressure of mixture is equal to the sum of their particles pressures;

   Partial pressure of methane  = 96.4kPa - (13.4kPa + 29.3kPa)

  Partial pressure of methane = 53.7kPa

answer; /// i do believe that the correct answer is (c)nuclear bond

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
