Question

Plz answer me the 5th one

Answer 1

Okay

So we have,




Ethanoic acid + sodium Hydrogen Carbonate ➡️ X (salt) + Y(gas)



Let's use the actual formuals instead,



CH3COOH + NaHCO3 ➡️ CH3COONa (sodium Ethonate) + CO2 (Carbon di oxide) +H2O (water)




So,
CH3COONa is the required salt X.
and CO2 is the required gas Y.

Answer 2

X = Sodium bicarbonate (NaHCO³)

Y = CO² gas (Carbon dioxide)

The Reaction is CH³COOH + NaHCO³ ------> CH³COONa + H²O + CO²

It is observed that lime water turns milky. Only carbon dioxide gas can turn lime water milky. So, this activity proves that when ethanoic acid reacts with sodium hydrogen carbonate, then carbon dioxide is evolved.
