Which combination describes the flame color of the compound when heated?
Which combination describes the flame color of the compound when heated?
What is the formula for the hydrated compound sodium sulfate decahydrate?
Na2SO4.10H2O
What is a reversible chemical reaction for the heating of hydrated copper sulphate?
The reversible chemical reaction for the heating of hydrated copper sulfate (CuSO4·5H2O) is: CuSO4·5H2O (blue) ⇌ CuSO4 (white) + 5H2O The blue hydrated copper sulfate loses its water molecules when heated to form white anhydrous copper sulfate and water molecules are released. This reaction is reversible, meaning the white anhydrous copper sulfate can regain water molecules to reform the blue hydrated copper sulfate under appropriate conditions.
Does a compound melt when heated?
Yes
Is NaCl decreases when heated to 90 degree C?
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).
A heated metal block volume decreases or increases?
It decreases
When air is heated air pressure decreases because the molecules?
when air is heated ,air pressure decreases because the molecules are

What is the formula for the hydrated compound sodium sulfate decahydrate?
Na2SO4.10H2O
What happens to the resistance of a metal when it is heated?
its resistence considerably decreases
What is the term a hydrate with the water heated off?
Anhydrous is the term for a hydrate with water heated off. when a hydrated salt is heated, it loses water of crystallization leaving an anhydrous salt.
If 5.742g of hydrated magnesium sulfate is heated 2.801g of anhydrous magnesium sulfate remains Determine the formula of the hydrated form?
The formula of the hyrdrated from should be MgSO4 . 3H2O.
What is a reversible chemical reaction for the heating of hydrated copper sulphate?

Does a compound melt when heated?
Yes
Why did barium chloride lose mass after being heated?
Crystallised BaCl2·2H2O will be de-hydrated when heated, loozing 2H2O per mol BaCl2·2H2O
What compound does not decompose when it is heated with a Bunsen burner?
Many salts do not decompose when heated.
What happens to a colour of a solute molecules when the solvent evaporates or boils?
The color of an anhydrous compound is sometimes different from the hydrated compound.
