If all the S2O32- (aq) in the solution in Part A is completely reacted with another substance over a 20.5 second period, what is the rate of decrease in M/s of the S2O32- (aq) in solution? (Assume no volume change.) Report your answer to 3 significant figures.

chemistry sucks a**

explanation:

the answer for sodium is 0.186

the answer for rubidium is 0.251

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.
