Question

........ Answer this...! ​

Answer 1

Q1 when lime water is reacted with carbon-dioxide it turns milky because White precipitate of calcium carbonate is formed in water.

Ca(OH)2 + CO2 --- CaCO3(White precipitate) + H2O

Q2 thus reaction is an acid and metal reaction in which after metal reacts with acid it gives salt and hydrogen gas

2Na + 2CH3COOH ---- 2CH3COONa + H2

Q3 to test if it is acid put a metal in both test tube the one reacting with it is acid since

Acid + metal --- salt + H2

Bring a burning matchstick near both the test tube the one which burns with a pop sound is acid liberating hydrogen gas.

The one not reacting is ethanol

Now it's correct
