When NaCl dissolves in water, the ΔHsol = +3.9 kJ/mol. Predict the volume of a NaCl solution with molarity = 2.5 mol/L that would experience an energy change of 45.6 kJ? Note: specific heat capacity H20 = 4.18 J/goC

Your answer should follow the format:

a) mols of NaCl to experience 45.6 kJ energy change

b) volume of 2.5M NaCl required (with units)

In a spacecraft, the following reaction occurs: co2(g) + 2lioh(s) -> lico3(s) + h2o(i) (i attached picture of equation) how many liters of carbon dioxide will 4 moles of lithium hydroxide (lioh) absorb? (one mole of any gads occupies 22.4 l under certain conditions of temperature and pressure. assume those conditions for this equation.) 45l 6.0l 3.0l 34l

Plz mark brainliest 30 points 1) find the momentum of a 12 kg snowball that is rolling with a velocity of 9 m/s. 2) an 8 ball with a mass of .5 kg is sitting at rest. it is hit by the cue ball (1 kg) traveling at 2.5 m/s. if the cue ball is at rest after the collision, how fast is the 8 ball traveling after the collision? 3) two football players are running toward each other. if the offensive player is 75 kg and is running 8 m/s, how fast must the 60 kg defensive player run in order for the two players to hit and stop?
