If 15.60 g of a hydrated compound is heated in an oven for several hours, its mass drops to 8.63 g. assuming that the reduction in mass is due to loss of water, what is the percentage of water in the original hydrate?

16. why must the number of electrons lost equal the number of electrons gained in every redox reaction? use 3 – 4 sentences in your own words to address this question. 18. what type of radiation is emitted when chromium-51 decays into manganese-51? show the nuclear equation that leads you to this answer. 19. a radioactive nucleus alpha decays to yield a sodium-24 nucleus in 14.8 hours. what was the identity of the original nucleus? show the nuclear equation that leads you to this answer.

What are the major types of a chemical compound

Iwould appreciate if someone could me.
