a chemist has a 75.0 gram sample of magnesium fluoride (MgF2). how many moles of this compound does the chemist have

Which material burns faster? metal aluminum

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?

From the choices provided below, list the reagent(s) in order that will react with cyclopentanone to form the compound shown below.
