What is the range of pH values in a basic solution? a.pH=7
b.pH is greater than 7
c.pH is between 0 and 14
d.pH is less than 7

Explanation:

b.pH is greater than 7

i m 100% sure

First, state the balanced equation that represents the combustion:

CH4 + 2O2 → CO2 + 2H2O

Second, state the molar ratios: 1 mol CH4 : 1 mol CO2.

Third, given that at constant temperature and pressure, the volume of an ideal gas is proportinal to the number of moles, you can state the volumetric proportion:

1 Liter of CH4 : 1 Liter of CO2.

Fourth, use the volumetric proportion:

2.0 Liter CH4 * 1 Liter CO2 /1 Liter CH4 = 2.0 Liter CO2.

2.0 Liter CO2.
