Answer:

Hydrochloric acid and neutralisation

Explanation:

1) Any acid+base reaction is a neutralisation reaction

Test for hydrogen:
If hydrogen is present in a test tube, a lighted splint held near its mouth ignites with a squeaky pop.

Test for Carbon Dioxide:
If carbon dioxide is bubbled through limewater, the limewater turns milky or cloudy white.

Sodium carbonate + ethanol = sodium ethoxide and hydrogen gas.
As mentioned above it ignites a lighted splint with a squeaky pop and does not make limewater cloudy/milky white, so ethanol is wrong.

Sodium carbonate + hydrochloric acid = sodium chloride, carbon dioxide and water
And as mentioned above, the solution when tested for carbon dioxide will turn cloudy when reacted with limewater.
