Please Help Me Which is an important step in the alternate method for balancing equations in redox reactions?
a.) indicating the types of bonds found in the molecules
b.) determining the speed at which reactions take place
c.) determining the half reactions of chemical equations
d.) indicating the temperature at which the reaction occurs

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?
