I disagree. Carbon is not a group 18 element. This is incorrect because elements closer to the top of the group are less reactive than those at the bottom of the group. Group 18 elements are noble gases and carbon, a group 14 element, is a non metal.
Answer:
An ion with 11 protons, 11 neutrons, and 10 electrons would have a charge of 1+, also expressed as a charge of positive one or +1.

Explanation:
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.
