A solution has a pOH of 8.7 so what is the pH of the solution? Is the solution acidic, basic, or neutral?

RSB [31]

PH + pOH = 14

pH = 14 - pOH

pH = 14 - 8.7

pH = 5,3

This solution is <u>acidic</u>.

If pH<7 - acidic
If pH=7 - neutral
If pH>7 - basic

A student carried out this reaction with methane as the limiting reagent. A 12.0 g quantity of methane was used, and the student

Sophie [7]

Answer:

The percent yield is 66.7%

Explanation:

1. The balanced chemical reaction to obtain carbon dioxide from the methane is:

$CH_{4}+2O_{2}=CO_{2}+2H_{2}O$

2. Calculathe the theoretical quantity of carbon dioxide.

As the problem says that the limiting reagent is the methane, all the calculations will be made from this quantity:

$12.0gCH_{4}*\frac{1molCH_{4}}{16gCH_{4}}*\frac{1molCO_{2}}{1molCH_{4}}*\frac{44gCO_{2}}{1molCO_{2}}=33gCO_{2}$

3. Calculate the percent yield:

Percent yield = $\frac{actualyield}{theoreticalyield}*100$

Percent yield = $\frac{22.0g}{33.0g}*100$

Percent yield = 66.7%
