Let's balance the chemical equation step-by-step. The unbalanced equation is: Ca(HCO₃)₂ + Ca(OH)₂ → XCaCO₃ + YH₂O Step 1: 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) = 8 Products (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) = 4 Step 2: Balance 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. Step 3: 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. Step 4: 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. Step 5: 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 + 2H₂O Therefore, X is 2 and Y is 2. What's next? 📸
