It will probably absorb water out of the air since it is hydrophilic. This will affect its molar mass.
Nothing will happen unless it evaporates. If left uncovered at 100C Sulfuric acid will dehydrate to form Sulfur trioxide and water.
The hydrated forms of these compounds are lower energy thermodynamically than the anhydrous forms. It takes heat energy to drive the water out of these salts to make them anhydrous. If left in the open, the anhydrous forms will take up water from the atmosphere and re-hydrate themselves. This process releases heat energy, so it "runs downhill" energy-wise.
CaCl2 is a hygroscopic substance that, if left open with oxygen, will absorb all the H2O from the atmosphere.
There is a bit of water left with some dissolvedsugar in it, therefore that stops the sugar crystals forming
BECAUSE it IS mostly sugar!

The product that is left after heating a hydrate is an anhydrous compound. This means that the water molecules in the hydrate have been removed through the process of heating, leaving behind the anhydrous form of the compound.
no
They may be unsafe to eat if left out overnight and should be thrown out.
does squash spoil if left overnight or two days

No. It is not safe to eat turkey left out overnight in any container.
No, it may not be safe to eat after being left out overnight.
it will burn
No. Stew left out overnight would not be safe to eat, covered or not - unless where it was left out was as cold as a refrigerator.
No.
It wouldn't be safe to eat salad that's been left out overnight.
