5. What reactions occurs when a solution of hydrochloric acid, HCl, is mixed with a solution of calcium hydroxide, Ca(OH)2?

(A) Cl + Ca(OH) --> HCa + Cl(OH)2
(B) HCl + Ca(OH)2 --> H(OH)2 + CaCl
(C) 2HCl + Ca(OH)2 --> 2H2O + CaCl2
(D) 2HCl + Ca(OH)2 --> H2Ca + 2ClOH
(E) HCl + Ca(OH)2 --> no reaction occurs


6. If the contents of the two beakers shown above (0.1 M of HCl, and 0.1 M of NaOH) are mixed, the resulting solution

(A) will turn red litmus paper blue
(B) will turn blue litmus paper red
(C) will resist large changes in pH
(D) will react with metals
(E) will not change the color of red or blue litmus paper


Please and thank you!
