balance equation CA(HCO3)2(aq) = CaCO3(s) + H2O(l) =CO2(g)
To balance the equation:
CA(HCO3)2(aq) = CaCO3(s) + H2O(l) + CO2(g)
First, let's balance the carbon. There are two carbon atoms on the left side but only one on the right side. To balance it, we can put a coefficient of 1 in front of CaCO3.
Ca(HCO3)2(aq) = 1CaCO3(s) + H2O(l) + CO2(g)
Next, let's balance the hydrogen. There are two hydrogen atoms in the Ca(HCO3)2 compound on the left side, but only two hydrogen atoms in H2O on the right side. To balance it, we can put a coefficient of 2 in front of H2O.
Ca(HCO3)2(aq) = 1CaCO3(s) + 2H2O(l) + CO2(g)
Finally, let's balance the calcium. There is one calcium atom in Ca(HCO3)2 on the left side and one calcium atom in CaCO3 on the right side. Calcium is already balanced.
Thus, the balanced equation is:
Ca(HCO3)2(aq) = 1CaCO3(s) + 2H2O(l) + CO2(g)
To balance the chemical equation Ca(HCO3)2(aq) = CaCO3(s) + H2O(l) + CO2(g), we need to ensure that the number of atoms of each element on both sides of the equation is the same. Here's how you can balance this equation:
First, let's start by balancing the calcium (Ca) atoms. There is one Ca atom on the left side and one on the right side, so calcium is already balanced.
Next, let's balance the hydrogen (H) atoms. We have two H atoms on the left side due to the (HCO3)2 ion. We can balance this by placing a coefficient of 2 in front of H2O on the right side, giving us 2 H atoms on each side.
Now, let's balance the carbon (C) atoms. We have two C atoms on the left side, one from each (HCO3)2 ion. Therefore, we need to put a coefficient of 2 in front of CaCO3 on the right side to have an equal number of C atoms on both sides.
Finally, let's balance the oxygen (O) atoms. On the left side, we have six O atoms (2 from HCO3 groups and 2 from one H2O molecule). On the right side, we have three O atoms from CaCO3. To balance the O atoms, we need to put a coefficient of 3 in front of the H2O on the left side. This will give us 6 O atoms on both sides.
The balanced equation will be:
Ca(HCO3)2(aq) = 2 CaCO3(s) + 3 H2O(l) + CO2(g)
So, to balance the equation, we placed the coefficients 2 in front of CaCO3, 3 in front of H2O, and left the coefficient 1 for Ca(HCO3)2 as it's already balanced.
Ca(HCO3)2(aq) ==> CaCO3(s) + H2O(l) + CO2(g)
Isn't that balanced as is (except for the obvious typose)
