Answer 2

It seems like you want to balance some chemical equations. To balance a chemical equation, you need to make sure that the number of atoms of each element is the same on both sides of the equation. Let's balance each of these equations:

1. ? + ? = NaCI + H20 + CO2 This equation is not balanced. To balance it, let's assign coefficients to each compound: ? + ? = NaCI + 1H20 + 1CO2 The balanced equation is: 1 NaOH + 1 H2CO3 = 1 NaCI + 1 H2O + 1 CO2

2. ? + ? = Al(OH)3 + KNO3 This equation is not balanced. To balance it, let's assign coefficients to each compound: 2Al + 6HNO3 = Al(OH)3 + 3KNO3 The balanced equation is: 2 Al + 6 HNO3 = 1 Al(OH)3 + 3 KNO3

3. ? + ? = CaCO3 This equation is not balanced. To balance it, let's assign coefficients to each compound: 1Ca + 1CO3 = CaCO3 The balanced equation is: 1 Ca + 1 CO3 = 1 CaCO3

4. ? + ? = AgCI + HNO3 This equation is not balanced. To balance it, let's assign coefficients to each compound: 3Ag + 4HNO3 = AgCI + 2H2O + 3NO The balanced equation is: 3 Ag + 4 HNO3 = 1 AgCI + 2 H2O + 3 NO

5. ? + ? = H3PO4 This equation is not balanced. To balance it, let's assign coefficients to each compound: 1H3PO4 = H3PO4 The balanced equation is: 1 H3PO4 = 1 H3PO4

6. ? + ? = ZnSO4 + Cu? This equation is not balanced. To balance it, let's assign coefficients to each compound: Zn + CuSO4 = ZnSO4 + Cu The balanced equation is: 1 Zn + 1 CuSO4 = 1 ZnSO4 + 1 Cu

Please double-check the equations and the balanced forms to ensure accuracy. If you have any other equations or questions, feel free to ask!
