Chemical analysis of a reaction mass resulting from the reaction of 2.000 grams of chromium ( molar mass= 52.0 g/mole) with pure oxygen (molar mass= 16.0 g/mole) yielded a material with a weight of 3.846 grams
which of the following was prepared? cr0, cr203,cr02 or cro3?

An empty fuel tank can still contain and therefore can be even more dangerous than one full of liquid fuel.

Explain why pure hydrogen cyanide does not conduct electricity, but become a conductor when it is dissolved in water? (at room temp, pure hcn exists as a volatile liquid)

The diagram below shows a cell placed in a solution.a cell is shown placed inside a beaker. it is labeled cell. the solution inside the beaker is labeled 40% salt solution and the solution inside the cell is labeled 20% salt solution.only water is allowed to move in and out of the cell. what will most likely happen to the cell? it will expand as water moves out of it. it will shrink as water moves out of it.it will expand as water moves into it. it will shrink as water moves into it.
