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 if 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 if he also adds substance A to X and Y. He will find out if 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 if X and Y are mixed together. Then, he should measure how long it takes if he also adds substance A to X and Y. He will find out if substance A is an enzyme.

Answer:

The last method provided in the question is correct.

Explanation:

By determining the time consumed for the liquid to become clear when X and Y are combined will permit the researcher to know the time of reaction and the progression of the rate of reaction. Post that similar method should be performed when the substance A is supplemented to the mixed liquids X and Y. If the reaction takes place at a brisk rate, then it can be confirmed that A functions as a catalyst for the reaction.

____are compounds that produce H+ ions in solution.
kap26 [50]

Answer:

An acid is a substance or compound that releases hydrogen ions (H+) when in solution. In a strong acid, such as hydrochloric acid (HCl), all hydrogen ions (H+), and chloride ions (Cl-) dissociate (separate) when placed in water and these ions are no longer held together by ionic bonding.
