Question
What is the balanced equation for the redox reaction between zinc and hydrochloric acid (HCl) that forms zinc(II) ions and hydrogen gas?A.2Zn + 2H+ 2Zn2+ + H2 + 2e-B.2Zn + HCl + H+ Zn2Cl + H2C.Zn + 2H+ 2Zn2+ + H2D.Zn + 2H+ 2Zn2+ + H2 + 2e-
Solution
The balanced equation for the redox reaction between zinc and hydrochloric acid (HCl) that forms zinc(II) ions and hydrogen gas is:
Zn + 2HCl → ZnCl2 + H2
Here's the step by step process:
- Write the unbalanced equation: Zn + HCl → ZnCl2 + H2
- Balance the equation for atoms other than H and O: Zn + HCl → ZnCl2 + H2
- Balance the equation for H and O atoms: Zn + 2HCl → ZnCl2 + H2
- Check if the charges are balanced: They are balanced as there are no charges in this reaction.
So, none of the options A, B, C, D are correct. The correct balanced equation is Zn + 2HCl → ZnCl2 + H2.
