10 KNO3 (s) + 8 C (s) +3 S (s) → 2 K2CO3 (s) + 3 K2SO4 (s) + 6 CO2 (g) + 5 N2 (g) If 75.35 grams of each reactant are combined in a reaction chamber and allowed to react completely, what is the total mass of solids after the reaction is finished? Your calculation should include contributions from reactants that are left over AND products that are formed - but remember, only solids. Answer in grams

39.7 mL of a 0.117 M Na2CO3 solution completely react with a 0.150 MHNO3 solution according to the following balanced chemical equation: Na2CO3(aq)+2HNO3(aq)→2NaNO3(aq)+CO2(g)+H2O(l) What mass (in grams) of carbon dioxide is formed? Express your answer with the appropriate units.

The octane rating of gasoline is a relationship of the burning efficiency of the given gasoline mixture to the burning efficiency of octane (C8H18). Like most hydrocarbons, octane reacts with oxygen gas to produce carbon dioxide and water.  2C8H18(g)+25O2(g)→16CO2(g)+18H2O(g) 0.180 molmol of octane is allowed to react with  0.790 molmol of oxygen. Which is the limiting reactant? How many moles of water are produced in this reaction? Express your answer with the appropriate units.   After the reaction, how much octane is left? Express your answer with the appropriate units.

In the "Methodé Champenoise," grape juice is fermented in a wine bottle to produce sparkling wine. The reaction is )) C6H1206(aq) → 2C2H50H(aq) + 2C02(g) Fermentation of 750. mL of grape juice (density = 1.0 g/cm3) is allowed to take place in a bottle with a total volume of 825. mL until 12.5% by volume is ethanol (C,H;OH). Assuming that the Co, is insoluble in H,0 (actually a wrong assumption), what would be the pressure of CO, inside the wine bottle at 25°C? (The density of ethanol is 0.79 g/cm3)
