Question 1: If pentane gas (C5H12) combusts with oxygen gas (O2) to form water (H2O) and carbon dioxide (CO2), how do I find a balanced chemical equation for this reaction? What is the scientific principle that requires the balancing of an equation to make it conform to reality?
Question 2: Methane (CH4), ammonia (NH3), and oxygen (O2) can react to form hydrogen cyanide (HCN) and water according to this equation: CH4 + NH3 + O2 à HCN + H2O. If I have 8 g of methane and 10 g of ammonia in excess oxygen, how do I find the balanced equation for this reaction? Which reagent is limiting and why? How do I find how many grams of hydrogen cyanide will be formed?
Question 3: What are the electron configurations of an electrically neutral atom of sodium, an electrically neutral atom of neon, and an electrically neutral atom of oxygen?
Question 4: What are the names of RbF, CuO, and (NH4)2C2O4 and what are the rules applied to determine these names?
Question 5: What type of reaction is 2Fe2O3 + 3C --> 4Fe + 3CO2 ? Why isn't it considered a single-displacement reaction? What are 2 different definitions of an oxidation-reduction reaction? How can I tell which reactant is reduced and which is oxidized? Which of these two definitions is generally found the most comprehensive?
