D. 2HCl - H2 + Zn + ZnCl2

Respuesta :

Answer:

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

[tex]\sf Zinc+Hydrogen\:Chloride \longrightarrow Hydrogen\:gas+Zinc\:Chloride[/tex]

  • Now write the equation

[tex]\sf Zn+HCL \longrightarrow H_2+ZnCl_2 [/tex]

  • Balance

[tex]\sf Zn+2HCL\longrightarrow H_2+ZnCl_2 [/tex]

  • option C is correct

Answer:
