Ответ:
1. No reaction.
2. ZnCl₂ + H₂
3. CaCl₂ + H₂
Explanation:
1. Cu + HCl —> ___
From the reactivity series of metals, H is higher that Cu in the series and so, Cu can not displace H from solution.
Therefore, no reaction will occur.
2. Zn + HCl —> ___
Zn is higher than H in the activity series so, it will displace H from acid solution to produce hydrogen gas, H₂.
The balanced equation is given below:
Zn + 2HCl —> ZnCl₂ + H₂
3. Ca + HCl —> ___
Ca is higher than H in the activity series so, it will displace H from acid solution to produce hydrogen gas, H₂.
The balanced equation is given below:
Ca + 2HCl —> CaCl₂ + H₂
