Question

Fe(OH)3+H2SO4 = ? K2CO3+H3PO4 =?

Answer 1

2Fe(OH)3+3H2SO4=Fe2(SO4)3+6H2O

3K2CO3+2H3PO4=2K3PO4+3H2CO3

Answer 2

To balance the chemical equations, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's balance the given chemical equations:

1. Fe(OH)3 + H2SO4 → ? (Unbalanced)

Balanced equation: Fe(OH)3 + 3H2SO4 → Fe2(SO4)3 + 3H2O

Explanation: Fe(OH)3 + 3H2SO4 → Fe2(SO4)3 + 3H2O

On the left side, we have 1 iron (Fe) atom, 3 hydrogen (H) atoms, 3 oxygen (O) atoms, 3 sulfur (S) atoms.

On the right side, we have 2 iron (Fe) atoms, 12 oxygen (O) atoms, 3 sulfur (S) atoms, and 6 hydrogen (H) atoms.

Now, the equation is balanced as the number of each element is the same on both sides.

2. K2CO3 + H3PO4 → ? (Unbalanced)

Balanced equation: K2CO3 + 2H3PO4 → 2KH2PO4 + CO2 + H2O

Explanation: K2CO3 + 2H3PO4 → 2KH2PO4 + CO2 + H2O

On the left side, we have 2 potassium (K) atoms, 1 carbon (C) atom, 3 oxygen (O) atoms, and 6 hydrogen (H) atoms.

On the right side, we have 2 potassium (K) atoms, 3 carbon (C) atoms, 8 hydrogen (H) atoms, and 7 oxygen (O) atoms.

Now, the equation is balanced as the number of each element is the same on both sides.
