Serious answers only! In the reaction of 1 mole of solid carbon with oxygen gas, the energy of the carbon dioxide gas produced is 393
kJ lower than the energy of the reactants.
1. Write out a balanced equation for the reaction - include the heat of the reaction
2. Is this reaction endothermic or exothermic, explain why.
3. Assuming there is an endless supply of C, how would increasing the amount of O2 molecules change the
rate of the reaction?
4. How would lowering the temperature affect the rate of reaction?

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?
