Question

2) conduct an activity to prove metal react with acid produced hydrogen gas.​

Answer 1

Answer:

hello dear. here is your answer.

When acids react with metals, they produce a salt and hydrogen gas. Most metals react with acids, but not all. The general equation that describes the chemical reaction between an acid and metal is metal + acid = salt + hydrogen gas.

Example: Iron + hydrochloric acid =iron chloride and hydrogen gas (Fe + 2CHI = FeCI2 + H2)

To write a general word equation for the reaction of metals and acids you to present it like this :

metal + acid = salt (metal + acid i.e magnesium sulphate) + Hydrogen

If you put a lit splint in the gas produced when a metal reacts with an acid it burns with a squeaky pop, due to the hydrogen created.

hope it helps.

Answer 2

Answer:

Na + HCL ----- Nacl + H2

Explanation:

Metals react with acid produce hydrogen gas. Hydrogen gas can be detected by pop sound which produce on putting a burning match stick.
