Q. Two reactants in a flask at room temperature are producing bubbles of a gas that run limewater milky. The rectants could be
When Magnesium carbonate (𝑀𝑔𝐶𝑂3) reacts with Hydrochloric acid (𝐻𝐶𝑙), the products will be Magnesium Chloride (𝑀𝑔𝐶𝑙2) and Carbonic acid. (𝐻2𝐶𝑂3).
Since 𝐻2𝐶𝑂3 is unstable in the troposphere ( the lowest part of atmosphere where we are living right now) and lower stratospehre in gas-phase, it will decompose into 𝐻2𝑂 and 𝐶𝑂2
When this reaction occurred, you can see some gas bubble (𝐶𝑂2) formed in it.
- zinc and hydrochloric acid
- magnesium carbonate and hydrochloric acid
- methane and oxygen
- copper and dulute hydrochloric acid
Answer: magnesium carbonate and hydrochloric acid
