$X$ is a silvery white metal. $X$ reacts with oxygen to form $Y$. The same compound is obtained from the metal on reaction with steam with the liberation of hydrogen gas.
Identify $X$ and $Y$.

Q. A metal 'X' is found in form of filing which burns vigorously when sprinkled on flame when these filings are heated with sulphur, a black coloured compound 'Y' is formed which is not attracted by magnet 'X' reacts with dil HCl to hydrogen gas 'X' reacts with steam to form 'Z' along with hydrogen gas. Identify 'X', 'Y' and 'Z' and write the chemical reactions involved?

Q. A compound X of the formula $C_2{H}_{6}O$, on reaction with Na metal gave Y, X also reacts with $PC{l}_5$ to give Z. The product obtained in the reaction between Y and Z is :

Q. A silvery-white metal $X$ reacts with water at room temperature to produce a water-soluble compound $Y$ and a colourless gas $Z$. The reaction is highly exothermic and the $Z$ catches fire immediately during the reaction. The solution of $Y$ in the water on reacting with a stoichiometric amount of dilute solution of hydrochloric acid gives a solution of $pH=7.0$.
The compounds $X,Y$ and $Z$ respectively are:

Q. A silvery white metal X reacts with water at room temperature to produce a water soluble compound Y and a colourless gas Z. The reaction is highly exothermic and the Z catches fire immediately during the reaction. The solution of Y in the water on reacting with the stoichiometric amount of dilute solution of hydrochloric acid gives a solution of pH = 7.0. The compounds X, Y and Z respectively are :

Q. A silvery-white metal X taken in the form of ribbon, when ignited, burns in air with a dazzling white flame to form a white powder Y. When water is added to powder Y, it dissolves partially to form another substance Z.
(a) What could metal X be?
(b) What is powder Y?
(c) With which substance metal X combines to form powder Y?
(d) What is substance Z? Name one domestic use of substance Z.
(e) Write a balanced chemical equation of the reaction which takes place when metal X burns in air to form powder Y.
