e) Heating of sugar.
Answers
Answer:
Explanation:
Zinc carbonate → zinc oxide + carbon dioxide Carbon dioxide gas is formed in this reaction.
Sodium Chloride + Silver nitrate → Silver chloride + Sodium nitrate A white precipitate (silver chloride) is formed in the above chemical reaction.
Sodium sulphite + hydrochloric acid → sodium chloride + water + sulphur dioxide Sulphur dioxide gas is formed in this reaction.
Sulphur dioxide + oxygen ⇌ Sulphur trioxide
Lead nitrate + ammonium hydroxide → ammonium nitrate + lead hydroxide Lead hydroxide is a chalky white precipitate formed in this reaction.
zinc carbonate + zinc oxide + carbon dioxide carbon dioxide gas is format in this reaction
sodium chloride + Silver Nitrate ----》 silver chloride + sodium nitrate a white precipitate silver chloride is format in the above chemical reaction
sodium sulphur + hydrochloride ------》 sodium chloride water + Sulphur Dioxide
Sulphur dioxide gas is format in this reaction
Sulphur dioxide ------》 Sulphur dioxide
