1) What dishes & substances are needed to find the molecular formula of CoCl2 · nH2O crystal hydrate? If possible, outline what the process might look like; 2) It is known that 32.5 g of anhydrous CoCl2 was obtained by heating 50 g of CoCl2 · nH2O crystal hydrate. What will be the molecular formula of the crystal hydrate?

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.

there are two significant figures.
