Calculate the mass per day (kg/d) of lime (Ca(OH)2) that will be required to precipitate phosphorus in a wastewater with 6.5 mg P/L. The wastewater flow rate is 10,000 m3 /d and the goal effluent P concentration is 0.1 mg P/L. Assume complete dissociation of lime in the wastewater and that the precipitation reaction proceeds at 100% efficiency according to the stoichiometric reaction below.
102+ +6P 3− +2H− ↔ (P ) (H) (s)

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?
