Answer 2

Solving the Equations:

To solve the given equations, we need to balance the chemical equations and determine the products formed. Let's go through each equation one by one:

1. H2SO4 + H2SiO3: - To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. - The balanced equation is: H2SO4 + H2SiO3 → SiO2 + H2O + H2SO3.

2. H2SO4 + CuCO3: - To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. - The balanced equation is: H2SO4 + CuCO3 → CuSO4 + CO2 + H2O.

3. H2SO4 + Cu(OH)2: - To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. - The balanced equation is: H2SO4 + Cu(OH)2 → CuSO4 + 2H2O.

4. H2SO4 + NaOH: - To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. - The balanced equation is: H2SO4 + 2NaOH → Na2SO4 + 2H2O.

5. H2SO4 + P2O5: - To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. - The balanced equation is: H2SO4 + P2O5 → H2S2O7 + H2O.

6. H2SO4 + Fe2O3: - To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. - The balanced equation is: H2SO4 + Fe2O3 → Fe2(SO4)3 + H2O.
