Hermione · Answer 1

Gas x would be carbon dioxide.

note / acid + carbonate - > salt + water + carbon dioxide

the white precipitate would be calcium carbonate. CaCo₃

note / this is a common eqn u need to remember.

X - CO₂ (carbón dioxide)

Y - CaCo₃ (calcium carbonate)

sodium carbonate is a basic salt
