The formula of calcium oxide is CaO. What is the formula of the ionic compound containing calcium and permanganate ions?

Explanation:

Chemical formula of a permanganate ion is and this ion has an overall charge of -1. On the other hand, calcium is an alkaline earth metal and it has a valency of +2. Therefore, when it will chemically combines with permanganate ion then according to cross-multiplication formula it will be multiplied by 2.

Therefore, we can conclude that the formula of the ionic compound containing calcium and permanganate ions is .

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
