1. A 26.3 gram sample of solid potassium chlorate decomposed and produced 9.45 grams of oxygen
gas. What is the percent yield for oxygen? (TY: 10.3g. 91.7%)
KCIO,(s)
2 KCl(s) + 3 0,(g)

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins. co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)

Which three statements represent the benefits of performing experiments using computer simulations?

Which conclusion fits the data in the table? a. heat chemically changes chocolate and margarine. b. all solids become liquid at 100°f. c. removing heat from a substance it to melt. d. matter may change shape when it is heated.
