What is the chemical formula for iron(III) chloride hexahydrate?

A 15.67 g sample of a hydrate of magnesium carbonate was heated to drive off the water. The mass was reduced to 7.58 g. What is the formula of the hydrate?

The word carbohydrate comes from the French term hydrate de carbone which means ______________.

Carbohydrates are sometimes called _____________.

It is the simplest carbohydrates or the simplest sugars.

A hydrate of magnesium chloride is present and the following data is collected:

mass of crucible = 22.05 grams

mass of crucible + hydrate = 25.95 grams

mass of crucible and contents after heating = 23.19 grams
