hydrogen gas (H2) and zinc chloride (ZnCl2).
Which equation represents this chemical reaction?
A. ZnCl2 + Zn - H2 + 2HCI
B. Zn - H2 + ZnCl2 + 2HCI
C. Zn + 2HCI - H2 + ZnCl2
D. 2HCl - H2 + Zn + ZnCl2

Answer 1

Step-by-step explanation:

Answer is C

Answer 2

Required Answer:-

• First rewrite the sentence that defines the equation

Zinc (Zn) combines with hydrogen chloride (HCI) to form hydrogen gas(H2) and zinc chloride (ZnCl2).

Chemical Equation

`\sf Zinc+Hydrogen\:Chloride \longrightarrow Hydrogen\:gas+Zinc\:Chloride`

• Now write the equation

`\sf Zn+HCL \longrightarrow H_2+ZnCl_2`

• Balance

`\sf Zn+2HCL\longrightarrow H_2+ZnCl_2`

• option C is correct
