what happens when (report only observations) (1) a reactive metal reacts with a dilute mineral acid? (2) an amphoteric oxide reacts with sodium hydroxide solution ? (3) a metal of low reactivity is dropped in the salt solution of a metal high reactivity ? (4) a metal carbonate is treated with acid ?
plzz give me answer plzz fast it's a urgent worl plzz

Answer:
1. Dilute acids react with relatively reactive metals such as magnesium, aluminium, zinc and iron. The products of the reaction are a salt plus hydrogen gas.
2. An amphoteric oxide is one which shows both acidic and basic properties.They react with sodium hydroxide to form salt sodium sulfate.
3. If a metal of low reactivity is dropped in Salt solution of a higer reactivity matal no chemical reaction will take place.
4. When acids react with carbonates, such as calcium carbonate (found in chalk, limestone and marble), a salt, water and carbon dioxide are made.
acid + metal carbonate → salt + water + carbon dioxide
I have explained it a bit so that it helps ...
if u found it helping then do follow me ...
thank u
have a great day ahead ...
