How many moles of sulfur dioxide are produced when 4.38 moles of oxygen completely react with iron (iv) sulfide

What happens to the temperature of a substance when the average kinetic energy of its particles increases?

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
