Ben will be conducting an experiment in which he reacts metals with different concentrations of acid in test tubes. what should ben wear to best protect himself during the experiment?
a)heat-proof gloves, a lab coat, and close-toed shoes
b)a lab coat, chemical gloves, and close-toed shoes
c)goggles, a lab coat, and heat-proof gloves
d)goggles, a lab coat, chemical gloves, and close-toed shoes

Option (D) is the correct answer.

Explanation:

During any kind of experiment in the laboratory, it is very important to take proper safety measures in order to protect oneself.

For example, we should wear loose cloths, googles, chemical gloves etc in order to ensure our safety in the laboratory.

Therefore, while conducting an experiment with metals and acids it is required that Ben should wear goggles, a lab coat, chemical gloves, and close-toed shoes.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

the ratio of the conjugate base to the acid required to attain the desired ph.
