Answer:
2HCl(aq) + Na2SO3(aq) —> 2NaCl(aq) + H2SO3(aq)
Explanation:
HCl(aq) + Na2SO3(aq) —> NaCl(aq) + H2SO3(aq)
Let us balance the equation. This is illustrated below:
There are 2 atoms of Na on the left side of the equation and 1atom on the right side. It can be balance by putting 2 in front of NaCl as shown below:
HCl(aq) + Na2SO3(aq) —> 2NaCl(aq) + H2SO3(aq)
Now, we have 2 atoms of Cl on the right side and 1 atom on the left side. Thus, it can be balance by putting 2 in front of HCl as shown below:
2HCl(aq) + Na2SO3(aq) —> 2NaCl(aq) + H2SO3(aq)
A careful look at the equation proved that the equation is balanced as the numbers of the different atoms of the element on both side of the equation are the same.
Answer:
2HCl (aq) + Na₂SO₃ (aq) → 2NaCl (aq) + H₂SO₃(aq)
Explanation:
We identify the reactants with its phases:
HCl (aq)
Na₂SO₃ (aq)
We identify the products:
NaCl(aq)
H₂SO₃ (aq)
We dissociates the reactants:
HCl (aq) + Na₂SO₃ (aq) → H⁺ + Cl⁻ + 2Na⁺ + SO₃⁻²
2H⁺ will bond the SO₃⁻² to make the acid
and the Cl⁻ will bond the Na⁺ to make the salt
The balanced equation is:
2HCl (aq) + Na₂SO₃ (aq) → 2NaCl + H₂SO₃
