A sample of limestone and other soil materials was heated, and the limestone decomposed to give calcium oxide and carbon dioxide. CACO3 (s)→ Ca0(s) + CO2(g) A 4.138 g sample of limestone-containing material gave 1.49 g of CO2, in addition to CaO, after being heated at a high temperature. What was the mass percent of CACO3 in the original sample? 63.9 %

Aluminum carbide, Al4C3, reacts with water to produce methane, CH4. Al4C3(s) + 12 H2O(l) 4 Al(OH)3(s) + 3 CH4(g) 1. If 125 g of aluminum carbide is decomposed, what is the theoretical yield of methane? (a) 4.64 g (b) 13.9 g (c) 415 g (d) 154 g
4.108 Elemental analysis is sometimes carried out by combustion of the sample. For a hydrocarbon, the only products formed are CO2 and H2O. If a 1.36-g sample of an unknown hydrocarbon is burned and 2.21 g of H2O is produced along with 4.07 g of CO2, what is the empirical formula of the hydrocarbon?
You take 1.00 g of an aspirin tablet (a compound consisting solely of carbon, hydrogen, and oxygen), burn it in air, and collect 2.20 g CO2 and 0.400 g H2O. You know that the molar mass of aspirin is between 170 and 190 g/mol. Reacting 1 mole of salicylic acid with I mole of acetic anhydride (C4H6O3) gives you 1 mole of aspirin and 1 mole of acetic acid (C2H4O2). Use this information to determine the molecular formula of salicylic acid.
The active ingredient in some antiperspirants is aluminum chlorohydrate, Al2(OH)5Cl. Analysis of a 2.000-g sample of antiperspirant yields 0.334 g of aluminum. What percent (by mass) of aluminum chlorohydrate is present in the antiperspirant? (Assume that there are no other compounds containing aluminum in the antiperspirant.)
Nitrogen gas (N2) and hydrogen gas (H2) react to form ammonia gas (NH3). Consider the mixture of N2 () and H2 () in a closed container as illustrated below: Assuming the reaction goes to completion, draw a representation of the product mixture. Explain how you arrived at this representation.
