Answer:

B) coefficient: subscript

Explanation:

Given

3H_2O

Required

What does 3 and 2 represents

On a general term:

In nA_m

n = The\ coefficient\ of\ A

And

m = The\ subscript\ of\ A

So, by comparing 3H_2O with the general term, nA_m

n = 3

m = 2

Hence,

3 = coefficient and 2 = subscript

What kind of solution would have a Kb value much greater than 1?
Marta_Voda [28]

Answer:

B. a strongly basic solution

Explanation:

Kb is base dissociation constant, which indicates how completely a base dissociates into its component ions in water. The greater the Kb value, the greater the alkalinity of the solution and vice versa.

Therefore, a solution with a Kb value much greater than 1, indicates a strongly basic solution, while a solution with a Kb value less than 1, indicates a weakly basic solution.
