sodium carbonate and chlorine

sodium hydroxide and sodium chloride

Answer 1

So, the easiest way to do this, is first write out each reaction. Chemistry is lame, for, if you don't know stuff beforehand, you will probably get the question wrong.
Anyhow, "hydroxide" is "OH^-1", and its a weak base. "HCl" is a very strong acid. When you combine them, you get "H2O" + Cl. Since "OH" has "Na" in front; NaOH, it becomes:
HCl + NaOH = NaCl + H2O
