Why is the chemical formula magnesium sulfide written as mgs and not mg2s2?

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.

The radius of an atom is closest in size to a
