Elements with eight valence electrons are unreactive.

The force it would take to accelerate an 900-kg car at the rate of 6m/s2

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.

An element becomes a positively charged ion when itloses protons.loses electrons.gains electrons.gains neutrons.
