5. When calcium carbonate is heated, it decomposes to form solid calcium oxide and carbon dioxide gas. How many grams of carbon dioxide will be produced if 23.83 g of calcium carbonate reacts completely? (5pts)
CaCO3 → CaO + CO2
100.09g 56.08g 44.01g
6. The first step in the industrial manufacture of nitric acid is the reaction of nitrogen trihydride with oxygen to produce nitrogen monoxide and water. If 824 g of nitrogen trihydride are used, how many moles of nitrogen monoxide will be produced? (4pts)
4NH3 + 5O2 → 4NO + 6H2O
17.04g 32.00g 30.01g 18.02g
7. The reaction between 64.00 g solid sodium metal and 80.00 g iron (III) oxide produces sodium oxide and metallic iron. (15 pts)
6Na + Fe2O3 → 3Na2O + 2Fe 22.99g 159.70g 61.98g 55.85g
Determine (Clearly label each answer)
the limiting reactant
the mass of solid iron produced
the mass of excess reactant that remains after the reaction is complete.
8. When excess potassium sulfate is added to a solution containing 0.500 g silver nitrate, solid silver sulfate is formed along with potassium nitrate. (7 pts)
K2SO4 + 2AgNO3 → Ag2SO4 + 2KNO3
174.27g 169.88g 311.81g 101.11g

Explanation:
A strong chemical bond is formed from the transfer or sharing of electrons between atomic centers and relies on the electrostatic attraction between the protons in nuclei and the electrons in the orbitals. ... A large difference in electronegativity leads to more polar (ionic) character in the bond.
