2 Chemical Equations 1. The actual knowledge about what products are produced in a chemical reaction is obtained by a. inspecting the chemical equation b. balancing the chemical equation c. laboratory analysis d. writing a word equation 2. Once the correct formula for a reactant in an equation has been written, the a. subscripts are adjusted to balance the equation b. formula should not be changed c. same formula must appear as a product d. symbols used in the formula must not be used on the product side of the equation 3. In writing an equation in which hydrogen gas appears as a product, the correct representation of hydrogen gas is a. H b. 2 H c. H 2 d. OH 4. In a chemical equation, the symbol is read a. aqueous b. goes c. yields d. points 5. In a chemical equation, the symbol is used for a(n) a. heated reactant b. gaseous reactant c. catalyst d. gaseous product 6. How would oxygen be represented in the formula equation for the reaction between methane (CH 4 ) and oxygen to yield carbon dioxide and water? a. oxygen b. O c. O 2 d. O 3 7. What is the ratio of hydrogen to chlorine in the equation H 2(g) + Cl 2(g) 2 HCl (g)? a. 1:2 b. 2:1 c. 1:1 d. 4:2 8. Balanced formula equations express all of the following EXCEPT a. experimentally established facts b. mechanisms by which reactants become restructured into products c. identities of reactants and products in a chemical system d. relative quantities of reactants and products in the system
