Calcium Carbonate combines with Hydrochloric acid to produce Calcium chloride and water and carbon dioxide. I have the skeletal equation of _Ca(CO3)+_HCl>_CaCl2+_H2O+_CO2 is that equation right? if so, how to I balance it?
CaCO3 + 2HCl>CaCl2 + H2O + CO2
To balance the equation for the reaction between calcium carbonate (CaCO3) and hydrochloric acid (HCl), you need to ensure that there is an equal number of atoms of each element on both sides of the equation. Here's how you can balance it step by step:
1. First, identify the number of each element present on both sides of the equation:
Ca: 1 on the left, 1 on the right
C: 1 on the left, 1 on the right
O: 3 on the left, 1 on the right
H: 1 on the left, 2 on the right
Cl: 0 on the left, 2 on the right
2. Start by balancing the atoms that appear in only one compound on each side of the equation. In this case, it is calcium (Ca). Therefore, place a coefficient of 1 in front of CaCl2 on the right side.
Ca(CO3) + HCl -> CaCl2 + H2O + CO2
3. Next, balance the carbon (C) and hydrogen (H) atoms. There is only one carbon atom on each side, so it is already balanced. However, there are two hydrogen atoms on the right side and only one on the left side. To balance hydrogen, place the coefficient 2 in front of HCl on the left side.
Ca(CO3) + 2HCl -> CaCl2 + H2O + CO2
4. Now, let's balance the oxygen (O) atoms. There are three oxygen atoms in the CaCO3 compound on the left side, while there is only one oxygen atom in the H2O compound on the right side. To balance this, we need to adjust the coefficient for CO2. For simplicity, we will place a coefficient of 3 in front of CO2.
Ca(CO3) + 2HCl -> CaCl2 + H2O + 3CO2
Now, all the elements on both sides of the equation are balanced. Thus, the balanced equation for the reaction is:
Ca(CO3) + 2HCl -> CaCl2 + H2O + 3CO2
