01:44:44 If a gas is moved from a large container to a small container but its temperature and number of moles remain the same, what would happen to the pressure of the gas? O It would increase. It would be halved.

Calculate the molarity of a solution containing 50.0g of CaBr2 in a 750.0mL solution?

Why sodium chloride is a neutral compound even though it is made up of ions that have positive and negative charges?

A student monitored the reaction rate of a 0.600M sucrose solution, at 25 oC, and determined that the reaction is first order with respect to sucrose. If at 25.0 oC it takes 3.33-hours for the concentration of the 0.600M solution to drop to 0.300M.
