1. Calculate the energy needed to break all the bonds 0.0960g of oxygen gas, 2.If the energy required to break bonds is greater than the energy transferred to the surroundings when bonds are made, will the reaction be exothermic or endothermic
3. What is meant by the bond energy of a chemical bond?
4.Write the balanced symbol equations and calculate the energy changes for the following chemical reactions:
hydrogen + chlorine -> hydrogen chloride
hydrogen + oxygen -> water

For the following dehydrohalogenation (e2) reaction, draw the zaitsev product(s) resulting from elimination involving c3–c4 (i.e., the carbon atoms depicted with stereobonds). show the product stereochemistry clearly. if there is more than one organic product, both products may be drawn in the same box. ignore elimination involving c3 or c4 and any carbon atom other than c4 or c3.

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?
