It's pressure.
The constant bombardment of gas molecules against the inside walls of a container produces pressure on the walls; gas pressure results from the collision of these particles on the walls at different velocities. This is known as the kinetic theory of gases. A gas is composed of a large number of submicroscopic particles (atoms or molecules) that are in constant and ...

The correct answer to this question is the oxidation number of Hydrogen in KH is -1. A few general rules apply when assigning oxidation numbers: a few of these include the oxidation number of an atom in an element is zero, and the algebraic sum of the oxidation numbers in the formula of a compound is zero.
Generally, Hydrogen in compounds has an oxidation number of +1, although in ...
