3HCl(aq)+HNo3(aq) Cl2(g)+NOCl(g)+2H2O(l)
Help me
with what?
3HCl(aq)+HNO3(aq) → Cl2(g)+NOCl(g)+2H2O(l)
is a balanced equation, so what's your question?
The given chemical equation represents the reaction between hydrochloric acid (HCl) and nitric acid (HNO3) to produce chlorine gas (Cl2), nitrogen monoxide chloride gas (NOCl), and water (H2O). Here's a step-by-step explanation of how to balance this equation using the method of balancing by inspection:
1. Count the number of atoms for each element on both sides of the equation. Start with an incomplete balance:
On the left side:
- Hydrogen (H): 3 in HCl + 1 in HNO3 = 4
- Chlorine (Cl): 1 in HCl + 0 in HNO3 = 1
- Nitrogen (N): 0 in HCl + 1 in HNO3 = 1
- Oxygen (O): 0 in HCl + 3 in HNO3 + 1 in H2O = 4
On the right side:
- Hydrogen (H): 2 in H2O = 2
- Chlorine (Cl): 2 in Cl2 + 1 in NOCl = 3
- Nitrogen (N): 1 in NOCl = 1
- Oxygen (O): 0 in Cl2 + 1 in NOCl + 2 in H2O = 3
2. Identify the elements that are unbalanced. In this case, chlorine (Cl) and oxygen (O) are not balanced.
3. Balance the atoms of the unbalanced elements one at a time. As chlorine (Cl) appears on both sides, we can start by balancing it first:
- There are 1 Cl on the left side, and 2 Cl on the right side. To balance the Cl atoms, we place a coefficient of 2 in front of HCl on the left side:
2HCl(aq) + HNO3(aq) Cl2(g) + NOCl(g) + 2H2O(l)
4. Next, we balance the oxygen (O) atoms. On the left side, there are 4 O atoms (3 from HNO3 and 1 from H2O), while on the right side, there are 3 O atoms (1 from NOCl and 2 from H2O). To balance the O atoms, we need to add another HNO3 on the left side:
2HCl(aq) + 2HNO3(aq) Cl2(g) + NOCl(g) + 2H2O(l)
Now, let's re-check the atom counts:
On the left side:
- Hydrogen (H): 6
- Chlorine (Cl): 2
- Nitrogen (N): 2
- Oxygen (O): 4
On the right side:
- Hydrogen (H): 4
- Chlorine (Cl): 2
- Nitrogen (N): 1
- Oxygen (O): 4
5. Finally, recheck the atom counts to ensure that all elements are balanced properly. In this case, all the atoms on both sides of the equation are balanced. Therefore, the balanced equation is:
2HCl(aq) + 2HNO3(aq) → Cl2(g) + NOCl(g) + 2H2O(l)
