Earlier in the lesson, you determined that the enthalphy for magnesium combustion could be computed using Hess’s law. The formula derived from the reaction equations was: Delta H shown in orange equals delta H 1 in green minus delta H 2 in purple plus delta h 3 in blue.

The enthalpy of the magnesium combustion is
kJ/mol.

What are the similarities of physical and chemical change ?

Plz mark brainliest 30 points1) 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?
