A researcher is designing a laboratory experiment to determine whether the inorganic substance A affects the rate of a
reaction between two colored liquids X and Y. When the reaction is complete the liquid is clear. The reaction between
X and Y is similar to one used by manufacturers to produce certain chemicals in factories.
Which method would best answer his question about reaction rate and what will he find out about substance A?
First, he should measure the final temperature of the liquid when X and Y react without substance A. Then, he
should measure the final temperature when he adds substance A to X and Y. He will find out it substance A is a
catalyst
First, he should measure how long it takes for the liquid to become clear if X and Y are mixed together. Then, he
should measure how long it takes it he also adds substance A to X and Y. He will find out it substance A is a
catalyst
First, he should measure the final temperature of the liquid when X and Y react without substance A. Then, he
should measure the final temperature when he adds substance A to X and Y. He will find out if substance A is an
enzyme
First, he should measure how long it takes for the liquid to become clear it X and Y are mixed together. Then, he

Astore manager timed janette to see how long it would take her to fold and put away a sweater, a shirt, a pair of pants, and a scarf. it took her 26.1 seconds for the shirt, 24.3 seconds for the sweater, 32.8 seconds for the pants, and 18.2 seconds for the scarf. what was the average time it took janette to fold and put away all four items? during a catered lunch, an average of 4 cups of tea are poured per minute. the lunch will last 2 hours. how many gallons of tea should the caterer bring if there are 16 cups in one gallon?
