The kinetics of decomposition of dinitrogen pentaoxide is studied at 50 degrees c and at 75 degrees c. which of the following statements concerning the studies is correct?
a. the rate at 75 will be greater thatn the rate at 50 because the activation energy will be lower at 75.
b> the rate at 75 will be greater thant the rate at 50 because the activation energy will be higher at 75.
c. the rate at 75 will be less than the rate at 50 because the molecules at higher speeds do not interact as well as those at lower speeds.
d. the rate at 75 will be greater than at 50 because the concentration of a gas increases with increasing temp.
e. the rate at 75 will be greater than the rate at 50 because the number of molecules with enought energy to react increases with increasing temp.

Which of the following will cause an increase in the acceleration of an object? increase force decrease force increase mass decrease mass

Which characteristics affect ocean water’s temperature? check all that apply. depth location mass salinity waves

Astudent made the lewis dot diagram of a compound as shown. mg is written with two dots shown on its top. an o is written on each side of mg. each o has six dots around it. an arrow is shown from one dot on mg toward the vacant space around the o on the right. another arrow is shown from the other dot on mg toward the vacant space around the o on the left. the title of the art is students lewis dot model. what is the error in the lewis dot diagram? an o atom should transfer all its six electrons to mg because the formula is mgo. both electrons of mg should be transferred to one o atom because the formula is mgo. the electrons should be transferred from each o atom to mg because mg has fewer electrons. the number of dots around mg should be four because it has to transfer two electrons to each o.
