Which of the following generally speed up a reaction? check all that apply. a. increasing the activation energy b. removing any catalysts c. adding more heat d. shaking the container holding the reaction

C and D

Explanation:

A. When you increase the activation energy, the reaction will be slowed down.

The energies that a certain number of molecules have to be equal to or greater than the activation energy so that a chemical reaction can occur. If we increase the activation energy, it is harder for the reaction to occur.

B. Catalysts play a role in lowering activation energy for a reaction to occur more easily. Hence, removing catalysts is not a way to speed up a reaction.

C. Adding more heat or D. Shaking the container holding the reaction are two options that can help the molecules contact one another more frequently, thereby facilitating the occurrence of reactions.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.
