Chemical Reactions Problem Set
This problem set was developed by S.E. Van Bramer for Chemistry 145 at Widener University.
- For the following reactions: Name the reactants and products, Balance the equation, and calculate the molecular weight of the reactants and products. Starting with 2.0 grams of each reactant, identify the limiting reagent and determine the mass of the first product.
- Fe2O3 (s ) + CO (g) -> FeO (s) + CO2 (g)
- FeO (s) + CO (g) -> Fe (s) + CO2 (g)
- C12H22O11 (s) + O2 (g) -> CO2 (g) + H2O (g)
- Fe (s) + O2 (g) -> Fe2O3 (s)
- Ca (s) + H2O (l) -> Ca(OH)2 (aq) + H2 (g)
- Write a balanced equation for the following reactions.
- Aluminum metal is oxidized by oxygen (from the air) to form aluminum oxide.
- Sodium oxide reacts with carbon dioxide to form sodium carbonate.
- Calcium metal reacts with water to form calcium hydroxide and hydrogen gas.
- Potassium nitrate decomposes to form potassium nitrite and oxygen.
- Barium metal reacts with Iron (III) sulfate to produce barium sulfate and iron
