Which of the following statements is completely correct? a. nh3 is a weak base, and h2co3 is a strong acid. b. h2co3 is a strong acid, and naoh is a strong base. c. nh3 is a weak base, and hcl is a strong acid. d. h2co3 is a weak acid, and naoh is a weak base. e. nh3 is a strong base, and hcl is a weak acid.

C) NH3 is a weak base (alkali), and HCl is a strong acid.

Explanation:

Remember that bases and acids are determined by the Ph of a the substances, NH3 has a Ph of 11 making it a weak base, strong bases have 12 or more, remember that neutral Ph is around 7, and HCl has a ph of 3.01 making it a strong acid, it has so the correct statement would be C) NH3 is a weak base (alkali), and HCl is a strong acid.

Remember that weak acids gor from 5 to 7 and weak bases go from 8-11
