How do you balance #HCl(l) + Zn(s) -> ZnCl + H_2(g) + 110kJ#?

Answer 1

#Zn(s) + 2HCl(aq) rarr ZnCl_2(aq) + H_2(g)#

Energy produced from exothermic reaction: 110kJ

When constructing a chemical equation, the energy generated from the should be positioned below the other components of the equation. It should not be overlooked.

Verify that the total number of atoms for all elements on the left and right sides of the equation adds up to one for each element.

To balance the chemical equation HCl(l) + Zn(s) -> ZnCl + H_2(g) + 110kJ, it should be:

2 HCl(l) + Zn(s) -> ZnCl2(aq) + H2(g) + 110 kJ

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
