Question

I need help with this question I will give brainliest if you get it right

Answer 1

The balanced equation :

2HCl + Zn ⇒ ZnCl₂ + H₂

Further explanation

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 :

2HCl + Zn ⇒ ZnCl₂ + H₂
