B. Catalyst B
C. Catalyst C
D. Catalyst D
Answer:
B. Catalyst B
Explanation:
Explanation: Enzymes are complex proteins that have a very specific shape. Just as a key fits a lock and allows it to open, the active site of the enzyme fits the reactants, allowing them to meet at the right orientation to form new chemical bonds. The shape of catalyst B is the best fit to the given reactants and product. The presence of catalysts allows reactions to proceed at much lower energy levels than without, as high-energy collisions between molecules are no longer necessary.

• turns blue litmus to red
• reacts with Zn(s) to produce gas bubbles
Which compound could be the solute in this solution?
(1) CH3OH (3) HBr
(2) LiBr (4) LiOH
A student tested a 0.1 M aqueous solution and made the following observations conducts electricity, turns blue litmus to red and reacts with Zn(s) to produce gas bubbles. The compound that could be the solute in this solution is HBr. The answer is number 3.
The only ionic compound which can react with Zn(s) toproduce gas bubbles is HBr.
An electrolyte is a solution that is able to conduct electricity. This solution must contain ions as ions are the charge carriers in solution.
In this case, we have to look at the options and discover the compounds that are made of ions and the only ionic compound which can react with Zn(s) toproduce gas bubbles is HBr.
