Step-by-step solution
5 stepsLet's balance the chemical equation step-by-step.
The unbalanced equation is:
Ca(HCO₃)₂ + Ca(OH)₂ → XCaCO₃ + YH₂O
Count the number of atoms for each element on both sides of the equation.
Reactants (Left Side):
Calcium (Ca): 1 (from Ca(HCO₃)₂) + 1 (from Ca(OH)₂) = 2
Hydrogen (H): 2 (from (HCO₃)₂) + 2 (from (OH)₂) = 4
Carbon (C): 2 (from (HCO₃)₂)
Oxygen (O): 6 (from (HCO₃)₂) + 2 (from (OH)₂) = 8Products (Right Side, with X=1, Y=1 initially):
Calcium (Ca): 1 (from CaCO₃)
Hydrogen (H): 2 (from H₂O)
Carbon (C): 1 (from CaCO₃)
Oxygen (O): 3 (from CaCO₃) + 1 (from H₂O) = 4Balance the Calcium (Ca) atoms.
There are 2 Ca atoms on the reactant side and 1 Ca atom on the product side. To balance this, we place a coefficient of 2 in front of CaCO₃.
Ca(HCO₃)₂ + Ca(OH)₂ → 2CaCO₃ + YH₂O
So, X = 2.Re-count atoms and balance Carbon (C) atoms.
Now, on the product side, we have 2 C atoms (from 2CaCO₃). On the reactant side, we also have 2 C atoms (from Ca(HCO₃)₂). Carbon is now balanced.
Balance the Hydrogen (H) atoms.
On the reactant side, there are 4 H atoms. On the product side, there are 2 H atoms (from H₂O). To balance this, we place a coefficient of 2 in front of H₂O.
Ca(HCO₃)₂ + Ca(OH)₂ → 2CaCO₃ + 2H₂O
So, Y = 2.Check the Oxygen (O) atoms to ensure everything is balanced.
Reactants: 6 O (from Ca(HCO₃)₂) + 2 O (from Ca(OH)₂) = 8 O
Products: 6 O (from 2CaCO₃) + 2 O (from 2H₂O) = 8 O
Oxygen atoms are balanced.The final balanced equation is:
Ca(HCO₃)₂ + Ca(OH)₂ → 2CaCO₃ + 2H₂OTherefore, X is 2 and Y is 2.
