The balanced equation :
2HCl + Zn ⇒ ZnCl₂ + H₂
<h3>Further explanation</h3>
Given
Reaction(unbalanced)
HCl + Zn ⇒ ZnCl₂ + H₂
Required
Balanced equation
Solution
Give a cofficient(the most complex compound=1)
aHCl + bZn ⇒ ZnCl₂ + cH₂
Make an equation
Zn, left = b, right = 1⇒b=1
Cl, left = a, right = 2⇒a=2
H, left = a, right = 2c⇒2c=a⇒2c=2⇒c=1
The equation becomes :
<em>2HCl + Zn ⇒ ZnCl₂ + H₂</em>

hopefully this is correct
You did not include the options but I can tell you the product ratio.
The product ratio is the mole ratio of the products of the reaction.
From the balanced chemical equation you have all the mole ratios:
The given equation is: 2 C6H5COOH + 15O2 --> 14 CO2 + 6H2O
The mole ratios are: 2 C6H5COOH: 15 O2: 14 CO2 : 6 H2O
The products are CO2 and H2O
Their mole ratio = 14 CO2 : 6 H2O
That can be expressed as:
14 mol CO2 7 mol CO2
----------------- = -----------------
6 mol H2O 3 mol H2O
It is also the same that:
6 mol H2O : 14 mol CO2
6 mol H2O 3 mol H2O
------------------ = -------------------
14 mol CO2 7 mol CO2
So, compare your options to the ratios show above and pick the proper ratio.
