To balance the chemical equation _____ CaO + _____ P4O10 → _____ Ca3(PO4)2, we need to determine the coefficients that will ensure that the number of atoms on both sides of the equation are equal.

1. Start by balancing the elements that are present in only one compound on each side of the equation. In this case, we have calcium (Ca), phosphorus (P), and oxygen (O).

2. Count the number of atoms of each element on both sides of the equation.

On the left side: 1 Ca, 1 O
On the right side: 3 Ca, 2 P, 8 O

3. Next, choose a coefficient for a compound containing an element that is present in only one compound on each side of the equation. In this case, we can start by balancing the calcium (Ca) atoms.

By placing a coefficient of 3 in front of CaO, we balance the calcium atoms:
3 CaO + _____ P4O10 → _____ Ca3(PO4)2

Now, we have: 3 Ca, 3 O on the left side and 3 Ca, 2 P, 8 O on the right side.

4. Next, balance the phosphorus (P) atoms. To do this, place a coefficient of 2 in front of P4O10:
3 CaO + 2 P4O10 → _____ Ca3(PO4)2

Now, we have: 3 Ca, 3 O on the left side and 3 Ca, 8 P, 40 O on the right side.

5. Finally, balance the oxygen (O) atoms. By placing a coefficient of 5 in front of Ca3(PO4)2, we balance the oxygen atoms:
3 CaO + 2 P4O10 → 5 Ca3(PO4)2

Now, we have: 3 Ca, 3 O on the left side and 15 Ca, 8 P, 50 O on the right side.

The balanced chemical equation is:
3 CaO + 2 P4O10 → 5 Ca3(PO4)2

To balance the chemical equation using ammonium nitrate (NH4NO3) → water (H2O) + nitrogen I oxide (N2O):

1. Write down the chemical formulas for all the reactants and products.

Ammonium nitrate: NH4NO3
Water: H2O
Nitrogen I oxide: N2O

2. Count the number of atoms of each element on each side of the equation.

On the left side: 2 N, 5 H, 3 O
On the right side: 2 N, 2 H, 3 O

3. Start by balancing the elements that are present in only one compound on each side of the equation. In this case, we can start with nitrogen (N).

Since there are already 2 nitrogen atoms on both sides of the equation, we don't need to adjust the coefficients for the nitrogen-containing compounds.

4. Next, balance the hydrogen (H) atoms. By placing a coefficient of 4 in front of the water (H2O), we balance the hydrogen atoms:
NH4NO3 → 2 H2O + N2O

Now, we have: 2 N, 8 H, 3 O on the left side and 2 N, 4 H, 3 O on the right side.

5. Finally, balance the oxygen (O) atoms. Since the number of oxygen atoms is already balanced, we don't need to make any further adjustments.

The balanced chemical equation is:
NH4NO3 → 2 H2O + N2O
