8. Baking powder is a mixture of tartaric acid $\left[{\mathrm{C}}_4{\mathrm{H}}_6{\mathrm{O}}_6\right]$ and sodium hydrogen carbonate [NaHCO 3$]$. One mole of tartaric acid reacts with two moles of sodium hydrogen carbonate. How many grams of tartaric acid are required to react with 100.00 grams of sodium hydrogen carbonate? 13. Iron metal reacts with hydrobromic acid according to the following reaction: $\mathrm{Fe}+\mathrm{HBr}?{\mathrm{FeBr}}_2+{\mathrm{H}}_2$ (a) Balance the equation. (b) Find the mass of $\mathrm{HBr}$ required to react with a rectangular iron bar with dimensions 2.00 inches by 4.00 inches by 8.00 inches. The density of iron is $7.86\mathrm{g}/{\mathrm{cm}}^3$. 14. Nitromethane $\left({\mathrm{CH}}_3{\mathrm{NO}}_2\right)\mathrm{can}$ be burned in air and used as a fuel; the combustion products are carbon dioxide, water and molecular nitrogen, ${\mathrm{N}}_2$. (a) Write a balanced equation for this reaction. (b) Determine the mass of oxygen required to react with 100.00 grams of nitromethane. 15. Calcium carbonate, also known as limestone, can be heated to form calcium oxide (lime) and carbon dioxide. (a) Write an equation for this reaction. (b) Determine the mass of lime that can be formed from one ton ( 2000.0 pounds) of limestone. Report your answer in pounds. (b) Provide formulas for the following compounds: Magnesium fluoride Calcium oxide Iron (II) sulfide (c) Provide formulas for the following compounds: Ferrous carbonate (iron forms $2+$ and $3+$ ions) Mercuric chloride (forms $1+$ and $2+$ ions) Magnesium phosphate 17. Suppose your car gets 30.00 miles per gallon at highway speeds. If you are driving at 55.00 miles per hour, how much gas is being consumed per second? How much oxygen is required to react with this amount of gas? You can consider gasoline to be the pure compound ${\mathrm{C}}_8{\mathrm{H}}_{18}$ with a density of $0.80\mathrm{g}/\mathrm{mL}$.
