Consider the following balanced equation for the following reaction: 15O2 (g) + 2C6H5COOH (aq) → 14CO2 (g) + 6H2O (l) Determine the amount of CO2 (g) formed in the reaction if the percent yield of CO2 (g) is 83.

Why does conduction occur in solids and liquids easier compared to gases? Because the particles in gases are closer together and move slower Because the particles in gases are farther apart and move faster.

Write a balanced equation for the combustion of gaseous methane (CH4), a majority component of natural gas, in which it combines with gaseous oxygen to form gaseous carbon dioxide and gaseous water.
