Which statement best describes balancing equations and the law of conservation of mass?
there are more atoms in the reactants than in the products, and the total mass is the same in the reactants and in the
products
the number of atoms is the same in the reactants and in the products, and the total mass is the same in the reactants and
in the products
there are fewer atoms in the reactants than in the products, and the total mass is less in the reactants than in the
products
there are more atoms in the reactants than in the products, and the total mass is higher in the reactants than in the
products

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
