Here is a science problem from Chemistry: Problem: Balance the following chemical equation: CH_4(g) + O_2(g) → CO_2(g) + H_2O(g) Step 1: Count the atoms of each element on both sides of the equation. Reactants: C: 1 H: 4 O: 2 Products: C: 1 H: 2 O: 3 Step 2: Balance the Carbon (C) atoms. The carbon atoms are already balanced (1 on each side). Step 3: Balance the Hydrogen (H) atoms. There are 4 H atoms on the reactant side and 2 H atoms on the product side. To balance, place a coefficient of 2 in front of H_2O on the product side: CH_4(g) + O_2(g) → CO_2(g) + 2H_2O(g) Step 4: Re-count atoms and balance the Oxygen (O) atoms. Reactants: C: 1 H: 4 O: 2 Products: C: 1 H: 2 × 2 = 4 O: 2 (from CO_2) + 2 (from 2H_2O) = 4 Now, there are 2 O atoms on the reactant side and 4 O atoms on the product side. To balance, place a coefficient of 2 in front of O_2 on the reactant side: CH_4(g) + 2O_2(g) → CO_2(g) + 2H_2O(g) Step 5: Verify that all atoms are balanced. Reactants: C: 1 H: 4 O: 2 × 2 = 4 Products: C: 1 H: 2 × 2 = 4 O: 2 (from CO_2) + 2 (from 2H_2O) = 4 All atoms are balanced. The balanced chemical equation is: CH_4(g) + 2O_2(g) → CO_2(g) + 2H_2O(g) That's 2 down. 3 left today — send the next one.
