List two sources of experimental error that might lead to a mass of reclaimed copper greater than that originally used. Correlate each error to a specific chemical reaction

Compared with the freezing-point depression of a 0.01 m c6h12o6 solution, the freezing-point depression of a 0.01 m nacl solution is

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.

What does the mass of 0.7891 mol of ferric oxide (fe2o3)
