Question

What substance would be soluble in water?

A - NH3 because it’s polar

B - BR2 because it’s non polar

C - H2 because it’s polar

D - CO2 because it’s non polar

Answer 1

A

Step-by-step explanation:

Since water is polar, we need for there to be a polar solute. This eliminates options B and D.

Now to choose between A and C, we can look at the compounds mentioned.

For A, NH3 is mentioned, which is a polar substance.

However, for C, H2 is mentioned, which is a nonpolar molecule, contrary to what is stated by the option.

Therefore, A is the answer.
