Question

Q8. Zn + n HCI → ZnCl2 + H2 The value of the coefficient "n" is
to obtained balanced equation.
O A.n=2
B. n = 3
O c. n=4
O D. n = 5​

Answer 1

Here it is your answer n=2(A)

Answer 2

Answer:

n = 2

Explanation:

Skeletal structure is

Zn + HCl → $ZnCl_{2} + H_{2}$

Left hand side of the equation has:

(a) 1 Zn

(b) 1 HCl which means 1 H and 1 Cl

Right hand side of the equation has:

(a) 1 $ZnCl_{2}$ which means 1 Zn and 2 Cl

(b) 2 H

Number of Zn is equal on both sides but there is 1 Cl and 1 H less on left hand side. Hence we add 2 (1 for the already existing H and Cl and 1 for the new one) on left hand side for compound having H and Cl

So, equation becomes

Zn + 2 HCl → $ZnCl_{2} + H_{2}$

Hence answer is n = 2
