since it is a strong acid then it dissociates completely and the ph will be :
-log (0.051)=1.29
Called electron cloud or orbitals or in quantum mechanics it's called energy levels
C, A, A, B, D. Hope this is correct! Have an awesome day!
I think these are the correct answers! I'm currently rechecking them and thought I would post this while I recheck the answers so that way you at least have something to go off of.

Answer:
Calcium carbonate and hydrochloric acid
Explanation:
The reaction of Calcium carbonate and Hydrochloric acid leads to the formation of Calcium Chloride and Carbon (IV) Oxide gas.
CaCO3 + 2HCl => CaCl2 + CO2 + H2O
