    Read the following paragraph carefully. To a small quantity of (X), a few drops of HCl are added. Consequently, a colorless, odorless gas (Y) is formed. This gas(Y) on passing through lime water turns it milky due to the presence of (Z), and then the milkiness disappears due to the formation of (W)
    Identify the compounds X, Y, Z, and W in the above change.

    During the laboratory preparation of carbon dioxide by using marble chips and hydrochloric acid, the following steps are followed. Arrange these steps in proper order.
    1. Through the mouth of the conical flask, a thistle funnel is inserted.
    2. Dilute hydrochloric acid is added dropwise through the thistle funnel so that the marble chips are completely immersed in the acid.
    3. A thistle funnel is inserted through one hole, and another hole, a delivery tube, is introduced.
    4. Marble chips are taken in a conical flask.
