Some salts make hydrates when there is moisture around. Some hydrate samples can absorb lights in visible legion. Therefore,
they show some colors. Thus, hydrates can be used to detect the moisture in the environment.
Let's say you are working in a laboratory with a group and you are the only student who has taken chemistry courses. Your
laboratory received a sample of cobalt(iI) chloride which has the formula CoCl2xH20. Let's say your boss asked you to find the
formula of this hydrate salt sample since you are the only chemist there. From your laboratory experience, simply explain the
experimental procedure you would follow to find the formula of this unknown sample.
Then, use the given data for the calculation part.
Mass of crucible: 32.27g
Mass of crucible + unknown hydrate: 33.92 g
Color of unknown hydrate: purple
Mass of crucible + anhydrous form of hydrate: 33.41 g
Color of anhydrous form: sky blue
The physical and chemical properties of a molecule depend on its structure. Here are two ball-and-stick models for two compounds that have the
same molecular formula but different structures and different chemical properties.
Ethanol
Dimethyl ether
How many of the following are ionic? NiCl 2 CaCl 2 Mg(OH) 2 SO 2 BaCl 2 C 6H 12O 6 O 2 CaCO 3

Since that time, however, important uses have been found for a number of noble gas compounds.

One reason it is preferred over certain other fluorinating agents is that the products of its fluorinating reactions are easily separated from the gaseous xenon. The following unbalanced equation represents one such reaction: S3O9 + XeF2 → S2O6F2 + Xe Balance this equation. What is the minimum number of moles of XeF2 necessary to react with 4 moles of S3O9?
