What is the importance of surface area (particle size), nucleation, and diffusion rate in terms of solid state reactions?
which of the following is not a representative particle?-atom-cation-anion-all of the
For the reaction [NH3] + [H3O+] draw the conjugate acid and base products of each reaction. Also determine whether the acid-base equilibrium would lie on the left or the right.
why doen't the mass number decrease? (because there is one less neutron). But the atomic number increases due. What happens to the electrons?
A student sets up two reactions. Reaction 1 uses 0.290 of reactant, and Reaction 2 uses 0.580 of reactant. How many times faster is Reaction 2 compared to Reaction 1. Express your answer as a multiple of the rate for Reaction 1 to three significan..
