C)HCL
D)HNO3

Answer 1

I know I'm late to answer but... ehh...

The correct answer is B) ammonia.

WHY?:

I took the test and got 4/5 correct & the feedback I got for this question was this, "Think about how to identify acids and bases." But my class average is a C....

Hope this helps you!!!!!! :)
