Asphere has a mass of 64 g, and a density of 2.0 g/cm3 . what is the radius of the sphere

Consider the reaction: n2(g) + o2(g) ? 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

According to coulomb's law, how would the electrical force between particles change if the product of their electrical charge increased?
