Sure, here are the balanced equations with short explanations:
Fe₂O₃ + 3CO → 2Fe + 3CO₂: This is the balanced equation for the reaction between iron oxide and carbon monoxide to produce iron and carbon dioxide. The equation is balanced with two Fe atoms, three O atoms, and three C atoms on both sides.
PbO + 4NH₃ → 2Pb + 4H₂O + 2N₂: This is the balanced equation for the reaction between lead oxide and ammonia to produce lead, water, and nitrogen gas. The equation is balanced with two Pb atoms, four H atoms, four O atoms, and two N atoms on both sides.
Answers & Comments
Answer:
To balance the equation:
PbO + NH3 → Pb + H2O + N2
We need to ensure that the same number of each type of atom is present on both sides of the equation.
Let's start by balancing the elements other than oxygen and hydrogen:
1. Balance the lead (Pb) atoms: There is one Pb atom on each side, so it is already balanced.
PbO + NH3 → Pb + H2O + N2
2. Balance the nitrogen (N) atoms: There is one N atom on each side, so it is already balanced.
PbO + NH3 → Pb + H2O + N2
Now let's balance the oxygen (O) atoms:
3. On the left side, there is one oxygen atom in PbO and one in NH3, for a total of 2 oxygen atoms.
PbO + NH3 → Pb + H2O + N2
4. On the right side, there is one oxygen atom in H2O and none in N2, so we have a total of 1 oxygen atom.
To balance the oxygen atoms, we need to add another PbO on the left side:
PbO + PbO + NH3 → Pb + H2O + N2
Now let's balance the hydrogen (H) atoms:
5. On the left side, there are three hydrogen atoms in NH3.
PbO + PbO + NH3 → Pb + H2O + N2
6. On the right side, there are two hydrogen atoms in H2O.
To balance the hydrogen atoms, we need to add a coefficient of 2 in front of NH3 on the left side:
PbO + PbO + 2NH3 → Pb + H2O + N2
Now the equation is balanced with respect to all elements.
The balanced equation is:
PbO + PbO + 2NH3 → 2Pb + H2O + N2
