Una muestra de vino tinto tiene una concentración de iones hidrogeno [H+] de 1.5×10^3, calcular la concentración de iones [OH-]

Arock can be broken down into different kinds of substances by physical processes. no chemical reactions are needed to separate different parts of a rock into pure substances. this is because a rock is a(n)

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?

Calculate the number of molecules present in 0.750 mol of mgo.
