Question

show that the reaction corbonats and meatal hydrogen corbonats with acids produce co2 gas
​

Answer 1

Answer:

hi

Explanation:

Metal carbonates and Metal Hydrogencarbonates reacts with acids and produces corresponding metal salt, carbon dioxide and water. ... Both the reaction produces CO2 which on passing through lime water makes lime water milky due to formation of calcium carbonate. On passing excess carbon dioxide following reaction occurs.

Answer 2

Answer

a) hydrogen gas

Explanation

Metals react with acids to produce hydrogen gas along with respective salt.

$acid+ metal➡️ metal salts+ H2 (G)$

This is because metals are electron donor. The hydrogen cation from acids accepts the electron from metal and thus forms hydrogen gas which is liberated as the reaction occurs.

Hydrogen gas can be tested by bringing a burning matchstick near the liberated gas. Hydrogen gas burns with pop sound.
