Cu+H2SO4-CUSO4+(+4) SO2+H2O

The equation you've provided appears to represent a chemical reaction between copper (Cu) and sulfuric acid (H2SO4), leading to the formation of copper(II) sulfate (CuSO4), sulfur dioxide (SO2), and water (H2O). To balance the reaction, we can break it down step by step. The unbalanced reaction is: \[ \text{Cu} + \text{H}_2\text{SO}_4 \rightarrow \text{CuSO}_4 + \text{SO}_2 + \text{H}_2\text{O} \] First, let's balance the number of copper (Cu), sulfur (S), oxygen (O), and hydrogen (H) atoms on both sides. 1. **Copper (Cu)**: There is 1 Cu atom on both sides. 2. **Sulfur (S)**: There are 2 S atoms on the right side (1 in CuSO4 and 1 in SO2) but only 1 on the left side from H2SO4. 3. **Hydrogen (H)**: There are 2 H atoms from H2SO4 and 2 from the water. They are balanced. 4. **Oxygen (O)**: The left side has 4 O from H2SO4, and the right side has 4 O (4 from CuSO4, 2 from SO2, and 1 from H2O, totaling 4). Based on this, we find we need to place a coefficient of 2 in front of H2SO4 to balance sulfur. The balanced equation would be: \[ \text{Cu} + 2 \text{H}_2\text{SO}_4 \rightarrow \text{CuSO}_4 + 2 \text{SO}_2 + 2 \text{H}_2\text{O} \] This shows that one copper atom reacts with two molecules of sulfuric acid to produce one molecule of copper(II) sulfate, two molecules of sulfur dioxide, and two molecules of water.
