substances that are involved in a chemical reaction?
2) What are coefficients and why are they used?
3) If a chemical equation is impossible to balance, what is most likely the problem?
4) Write and balance each of the following equations:
a. phosphorus plus oxygen yields diphosphorus pentoxide
b. sodium nitrate decomposes into sodium nitrite and oxygen
c. octane (C8H18) plus oxygen completely combusts into carbon dioxide and water
d. sulfuric acid plus sodium hydroxide yields sodium sulfate and water
5) Classify each type of reaction in question 4 above.
6) Complete and balance each of the following chemical equations.
a. Sr + S -->
b. bismuth + sulfur -->
c. potassium phosphate + barium chloride -->
d. calcium + water -->
e. aluminum + chlorine -->
7) Classify each type of reaction in question 6 above.
8) Write and balance the following equations.
a. ammonia yields nitrogen plus hydrogen
b. barium acetate plus sodium phosphate yields barium phosphate and sodium acetate
c. zinc plus hydrochloric acid produces zinc chloride and hydrogen gas
9) Classify each type of reaction in question 8 above.
10) Reusable booster rockets are employed to launch United States space shuttles. The
rockets use a mixture of aluminum and ammonium perchlorate for fuel. Balance the
equation that shows teh chemical reaction between these two substances knowing that
the 4 products are aluminum oxide, aluminum chloride, nitrogen monoxide, and water.
