79. a block of silver (sh=0.057cal/gc) weighing 55.og was heated to a temperature of 98.4c. it was
transferred to a calorimeter containing 100.og of water. the maximum temperature experienced by the
calorimeter system was 26.5c. you realize you didn't take the initial temperature of the water. assuming
complete heat transfer, can you calculate the initial temperature of the water?

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
