Please balance this equation

__HCl+__CaCO(3)-->__CaCl(2)+__H(2)O+__CO…

Sorry it's all confusing

Just count how many of each element are on each side of the equation.
Left:
1 Hydrogen
1 Chlorine
1 Calcium
1 Carbon
3 Oxygen

Right:
1 Calcium
2 Chlorine
2 Hydrogen
2 Oxygen
1 Carbon

Now try to change the amounts of each of compounds on both sides of the equation so that you have the same number of each element on each side of the equation.
