When a 2.00 g sample of RbBr is dissolved in water in a calorimeter that has a total heat capacity of 0.854 kJ⋅K−1, the temperature decreases by 0.310 K. Calculate the molar heat of solution of RbBr.

The minerals found in bones are deposited by living cells called

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.

The volume of helium in a blimp is 6.28 x 10^9 millimeters. the density of helium in the blimp is .1786 kilogram/meter^3. find the mass of the helium in the blimp.
