An electron in n = 5 level of an H atom emits a photon of wave length 1281nm. To what energy level does the electron make a transition from n = 5 to nf? Where nf

1. calculate the approximate enthalpy of the reaction in joules. estimate that 1.0 ml of vinegar has the same thermal mass as 1.0 ml of water. iqnore the thermal mass of th sodium bicarbonate. note: it takes about 4.2 joules () to change 1.0 gram (1.0ml) of water 1.0 c

Temperature is _related to the average kinetic energy of a gas. inversely directly not disproportionally
