Answer 2

Balancing Chemical Equations

To balance the given chemical equations, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's balance each equation one by one:

1. K2O + H2O = ? To balance this equation, we need to ensure that the number of potassium (K) and oxygen (O) atoms is the same on both sides. The balanced equation is: K2O + H2O = 2 KOH [[1]]

2. Ca + H2SO4 = ? To balance this equation, we need to ensure that the number of calcium (Ca), hydrogen (H), sulfur (S), and oxygen (O) atoms is the same on both sides. The balanced equation is: Ca + H2SO4 = CaSO4 + H2 [[2]]

3. P2O5 + H2O = ? To balance this equation, we need to ensure that the number of phosphorus (P) and oxygen (O) atoms is the same on both sides. The balanced equation is: P2O5 + 3 H2O = 2 H3PO4 [[3]]

4. Na2CO3 + H2SO4 = ? To balance this equation, we need to ensure that the number of sodium (Na), carbon (C), hydrogen (H), sulfur (S), and oxygen (O) atoms is the same on both sides. The balanced equation is: Na2CO3 + H2SO4 = Na2SO4 + H2O + CO2 [[4]]

5. Cu + HCl = ? To balance this equation, we need to ensure that the number of copper (Cu), hydrogen (H), and chlorine (Cl) atoms is the same on both sides. The balanced equation is: Cu + 2 HCl = CuCl2 + H2 [[5]]

6. Na2O + H3PO4 = ? To balance this equation, we need to ensure that the number of sodium (Na), oxygen (O), hydrogen (H), and phosphorus (P) atoms is the same on both sides. The balanced equation is: Na2O + 2 H3PO4 = 2 NaH2PO4 [[6]]
