Answer:

Chromium oxidation state is 3.

Formula Cr2(SO4)3

Explanation:

At the beggining of the exercise, the chromium sulfate, says the oxidation state of chromium in romans numbers (III). This number usually indicates the oxidation state of any element. In this case the Chromium shouldhave an oxidation state of 3.

Now, in order to form the chromium(III) sulfate we need to make a reaction between the sulfuric acid and chromium. In this case:

Cr + H2SO4 ---------> Cr2(SO4)3 + H2O

That's why the chromium sulfate has that formula.

Explain why a propane torch is lit inside a hot air balloon during preflight preparations. Which gas law applies?
Olegator [25]

Propane torch is lit inside a hot air balloon during pre-flight preparation because the heat from the touch is needed to heat the cold air inside the balloon, so that the air will expand and become less dense and rise, thus providing a lift for the balloon. This is line with charle's law, which states that, the volume of a fixed mass of ideal gas is directly proportional to the absolute temperature. This law implies that, as the temperature of the air inside the balloon increase, the volume of the balloon also increases.
