Consider the balanced equation: 2 N2H4 (g) N2O4 (g) --> 3 N2(g) 4 H2O(g) How many moles of H2O would form if 9.75 moles of N2H4 completely react

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.

How many moles is 14.5 cm^3 of platinum? the density of platinum is 21.45 g/cm^3.
