It is often possible to change a hydrate into an anhydrous compound by heating it to drive off the water (dehydration).
A 30.36 gram sample of a hydrate of MnSO4 was heated thoroughly in a porcelain crucible, until its weight remained constant. After heating, 27.12 grams of the anhydrous compound remained. What is the formula of the hydrate?
Use a period instead of a dot in the formula of the hydrate.
To an open beaker containing 500ml of water at 298k, 20g of sodium metal is added. the reaction proceeds quite rigorously but ultimately comes to rest after consuming all of the sodium metal and thermally reequilibrating with the surroundings. The..
