3.00 g of the hydrate CoCl2.xH2O was heated and after the water was driven off, 1.64 g of CoCl2 remained. (Use these atomic masses: Co = 59 Cl= 35.5 H = 1 O =16 ) You are required to find x by following the steps outlined below.
Find the following:
a. The mass of water driven off
b. The number of moles of H2O driven off
c. The number of moles of CoCl2 formed
d. The number of moles of H2O divide by the number of moles of CoCl2 = x (write as a whole number)
e. The full formula of the 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.
