You are only allowed to ask one question at a time so I edited down your question accordingly.  We need to convert the following to a balanced chemical equation: copper (2) carbonate plus hydrochloric acid gives copper chloride plus water plus carbon dioxide.  The chemical equation is written below:

CuCO3 + HCl --> CuCl2 + H2O + CO2

We can see that the number of all of the elements balances out on each side of the equation except for chlorine and hydrogen.  This can be remedied by adding a 2 in front of the HCl.  This gives the balanced chemical equation as written below:

CuCO3 + 2HCl --> CuCl2 + H2O + CO2
