Identify (X) and (Y) ?

In one of the industrial processes used for manufacture of sodium hydroxide, a gas ‘X’ is formed as a by-product. The gas ‘X’ reacts with lime water to give a compound ‘Y’ which is used as a bleaching agent in the chemical industry. Identify ‘X’ and ‘Y’ giving the chemical equations of the reactions involved.

Of the three metals X,Y and Z, X reacts with cold water, Y with hot water and Z with steam only. Identify X,Y and Z also arrange them in order of increasing reactivity.

When a metal X is treated with cold water, it gives a basic salt Y with molecular formula XOH (Molecular mass=40) and liberates a gas Z which easily catches fire. Identify X,Y and Z and also write the reaction involved.

A metal carbonate X on reacting with an acid gives a gas which when passed through a solution gives the carbonate black. On the other hand, A gas G that is obtained at anode during electrolysis of brine is passed on dry Y, it gives compound Z, used for disinfecting water. Identify X, Y, G and Z.

Identify the product Y in the sequence. CH_3 CHO + CH_3 MgBr overset("Ether")to X overset(H_2O//H^(+))to Y

Identify the terms and factors in the expressions given below xy+3y^(2)

Compound X and aluminium are used to join railway tracks. Identify the compound X?

A uniform magnetic field gets modified as shown in the figure. When the two specimens X and Y are placed in it. Identify the specimans X and Y.
