3Ca + 2H3PO, Caz(PO4)2 + 3H2 When 35.5 g of calcium is reacted with 52.3 g phosphoric acid, what volume, in liters, of hydrogen gas will be produced at STP? How much excess reactant will remain?

Determine the energy released per kilogram of fuel used. given mev per reaction, calculate energy in joules per kilogram of reactants. consider 1 mole of tritium plus 1 mole of deuterium to be a mole of “reactions” (total molar mass = 5 grams).

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.

Identify a strong intermolecular force of attraction between an alcohol
