When hydrated ferrous sulfate is heated, it loses its water molecules and undergoes thermal decomposition. The color change is from pale green (hydrated) to white (anhydrous).
When hydrated copper sulfate is heated, it loses its water molecules to form anhydrous copper sulfate. Since the molar ratio between the two forms is 1:1, if 6.4 moles of hydrated copper sulfate is heated, 6.4 moles of anhydrous copper sulfate will be produced.
No, NaCl (sodium chloride) does not decrease when heated to 90 degrees Celsius. Heating NaCl at this temperature will not cause it to decompose or decrease in quantity – it will remain the same compound, only in a different physical state (solid to liquid).
Pouring water on it because when it is heated it turns to an endothermic reaction and the hydrated part is boiled put of the compound it is then Anhydrous copper sulphate. When you add water it is hydrated again and this is an exothermic reaction. Which can get extremely hot so don't pour it on your hand and then hydrate it.
Yes, a continuous spectrum can be produced by a heated ionic compound. When an ionic compound is heated, electrons can be excited to higher energy levels, and as they return to their ground state, they emit light across a wide range of wavelengths, resulting in a continuous spectrum.

It decreases
when air is heated ,air pressure decreases because the molecules are
When copper is heated in oxygen, the compound formed is copper oxide.
its resistence considerably decreases
When hydrated copper sulfate is heated, it loses its water molecules to form anhydrous copper sulfate. Since the molar ratio between the two forms is 1:1, if 6.4 moles of hydrated copper sulfate is heated, 6.4 moles of anhydrous copper sulfate will be produced.
The compound formed when magnesium and sulfur are heated is magnesium sulfide (MgS).
Crystallised BaCl2·2H2O will be de-hydrated when heated, loozing 2H2O per mol BaCl2·2H2O

The color of an anhydrous compound is sometimes different from the hydrated compound.
Water vapors and sulfur dioxide are released.
