Compound & Product – Organic Chemistry Quiz
Balance the chemical equation below using the smallest possible whole number stoichiometric coefficients.
Answer
CH3CH2CH3 (g) + 5O2 (g) —> 3CO2 (g) + 4H2O(g)
Acetylene (C2H2) gas is often used in welding torches because of the very high heat produced when it reacts with oxygen (O2) gas, producing carbon dioxide gas and water vapor. Calculate the moles of water produced by the reaction of 1.7 mol of oxygen. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits.
Answer
0.68 mol
Methane (CH4) and oxygen (O2) gas react to form carbon dioxide (CO2) gas and water (H2O) vapor. Suppose you have 11.0 mol of CH4 and 1.0 mol of O2 in a reactor.
Calculate the largest amount of CO2 that could be produced. Round your answer to the nearest 0.1 mol.
Answer
0.5 mol
Gaseous methane (CH4) will react with gaseous oxygen (O2) to produce gaseous carbon dioxide (CO2) and gaseous water (H2O). Suppose 6.58 g of methane is mixed with 48. g of oxygen. Calculate the maximum mass of water that could be produced by the chemical reaction. Round your answer to 3 significant digits.
Answer
14.8 g
