Increasing temperatures in a reaction increases the kinetic energy of the reactant molecules. This causes them to move fast and hence collide with a higher frequency. The higher the rate of collision between the molecules, the faster the reaction.
Answer:
answer is A. a saturated hydrocarbon that has more than 35 carbons in its chain
Explanation:

Answer:
V=?
S=25m
t=2.5s
V=S/t
V=25/2.5
V=10m/s
So, the ball was traveling with the speed of 10m/s.
The combination of seatbelts and airbags can reduce the risk of death in a collision by up to 80%.
The seatbelts help to keep the person in one position and prevent impact with the vehicle as the vehicle comes to a sudden stop. Moreover, the airbag increases the time of collision to reduce the impact experienced by the person. An increased time of collision greatly reduces the damage that is done to the body.
When iron loses the 2 4s electrons, it attains a valency of +2. Sometimes, iron will also lose one of the paired electrons from 3d orbital, leaving the entire 3d orbital filled with unpaired electrons (which provides a more stable configuration). In this case, its valency will be +3.
