What happens to water molecules when they are heated?

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

Achange in the number of neutrons in an atom will change an blank . when the number of protons changes in an atom, a new element will form.
