Hey dear,
You missed the options.
1) Iron fillings
2) Magnesium ribbon
3) Charcoal powder
4) Copper wire
● Answer -
Charcoal powder
● Explanation -
- Metals generally react with acids to form metal salts and release H2 gas (which makes pop sound with matchstick).
2Fe + 6HCl --> 2FeCl3 + 3H2
Mg + 2HCl --> MgCl2 + H2
Cu + 2HCl --> CuCl2 + H2
- Non-metals don't react with acids.
C + HCl --> NO REACTION
Hope this helps you...
