I am 10 years old and have just started High School so please don't be sarcastic about doing my homework or asking me to buy a GSCE revision book thanks

They will produce salt and water. The salts would be
calcium chloride
magnesium chloride
sodium chloride.

When an alkali is neutralised by an acid a salt and water is formed.
So Calcium hydroxide will react with Hydrochloric acid to form Calcium chloride (salt) and Water (H2O).
Ca(OH)2 (aq) + HCl (aq)--> CaCl2 (aq) + H2O (l)
Similarly,
Mg(OH)2 (aq) + HCl (aq) --> MgCl2 (aq) + H2O (l)
NaOH (aq) + HCl (aq) --> NaCl (aq) + H2O (l)
aq = aqueous solution
l = liquid state

CaOH + 2HCl = CaCl2 +H2O
MgOH + 2HCl = MgCl2 +H2O
NaCl + HCl = NaCl + H20
Ca and Mg have a valency of 2, Na has a valency of 1

BBC BItesize is a good site for chemistry GCSE. Has all this stuff with practice tests and good explanations. Just google BBC BItesize.

See answer from 'dinu' unless you want an ion specific equation.
But also I suggest that you also in future do your own Homework.
