The rate of reaction (reaction rate) is the
time it takes for a chemical reaction to
occur. the reaction rate is controlled by
many factors, including the
concentration of the reactants, the
temperature, the surface area, pressure,
and the presence of the catalyst.
many people are familiar with the rate of
reaction as a result of using sugar to
sweeten either hot or cold tea. sugar
dissolves faster in a warm liquid than in
a cold liquid – this is an example of how
temperature influences the reaction rate

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?
