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 and also arrange them in order of increasing reactivity.

Which of the following metals, does not react with cold or hot water but reacts with steam?

Which of the following metals does not react with cold or hot water but reacts with steam?

This metal does not react with cold as well as hot water but reacts with steam.

Consider the compound and arrange X,Y, Z in order of increasing acid strengths .

The elements ,X ,Y and Z react as follows X_(2)O_(3) + 2Y to Y_(2)O_(3) +2X Y_(2) O_(3) +3C to 3CO +2Y Arrange the elements X,Y and Z in the order of their decreasing reactivity.

A metal X reacts with water to produce a highly combustible gas Y, and a solution A. Another metal P reacts with Z to give the same gas Y, Z, Y, Z and P respectively are
