Answer

1) 1 Na_{2}CO_{3}(aq) + 1 H_{2}SO_{4}(aq) \rightarrow 1 CO_{2}(g) + 1 H_{2}O(l) + 1 Na_{2}SO_{4}(aq) ### 2) 2 NaOH(aq) + 1 H_{2}SO_{4}(aq) \rightarrow 2 H_{2}O(l) + 1 Na_{2}SO_{4}(aq) Explanation 1. Balance Sodium (Na) in Equation 1 Sodium appears as Na_2 on both sides. Coefficient for Na_2CO_3 and Na_2SO_4 is 1. 2. Balance Carbon (C) in Equation 1 One carbon atom in Na_2CO_3 produces one CO_2. Coefficient for CO_2 is 1. 3. Balance Hydrogen (H) in Equation 1 Two hydrogen atoms in H_2SO_4 produce one H_2O. Coefficient for H_2O is 1. 4. Balance Sulfur (S) in Equation 1 One sulfur atom in H_2SO_4 matches with Na_2SO_4. Coefficient for H_2SO_4 is 1. 5. Balance Oxygen (O) in Equation 1 Oxygen balances automatically with the above coefficients. 6. Balance Sodium (Na) in Equation 2 Two sodium atoms needed to form Na_2SO_4. Coefficient for NaOH is 2. 7. Balance Hydrogen (H) in Equation 2 Four hydrogen atoms from two NaOH and one H_2SO_4 produce two H_2O. Coefficient for H_2O is 2. 8. Balance Sulfur (S) in Equation 2 One sulfur atom in H_2SO_4 matches with Na_2SO_4. Coefficient for H_2SO_4 is 1. 9. Balance Oxygen (O) in Equation 2 Oxygen balances automatically with the above coefficients.
