What does activation energy has to do with a chemical reaction.
asambeis [7]

Explanation:

Activation energy and reaction rate

The activation energy of a chemical reaction is closely related to its rate. Specifically, the higher the activation energy, the slower the chemical reaction will be. ... The released energy helps other fuel molecules get over the energy barrier as well, leading to a chain reaction.

Which is not a characteristic of chemical energy? A. chemical change B. breaking bonds C. splitting nuclei D. reacting substance
Delvig [45]

The correct answer is C. Splitting Nuclei.

Splitting nuclei is not a characteristics of chemical energy.

Chemical energy is termed as the energy which results when there is chemical reaction. Chemical energy is being stored in molecules which makes substance and bonds of atoms.

In order for our bodies to function well they need chemical energy. During photosynthesis plants perform chemical reaction each and every day.

A race car starting from rest accelerates uniformly at a rate of 3.90 m/s^2 what is the cars speed after it has traveled 200 m.
snow_tiger [21]
The formula for accelerational displacement is at^2/2, so we know that 3.9t^2/2 = 200, or 3.9t^2 = 400. t = \sqrt{400/3.9} \approx 10.12739367, at = v, so 3.9 * 10.12739367 \approx 39.5  m/s

In the future, people will only enjoy one sport: Electrodes. In this sport, you gain points when you cause metallic discs hoveri
pochemuha

Answer:

  • Disk C and Disk D

Explanation:

The total charge in the disks

q_1 + q_2 = q_{total}

must be conserved before and after bringing them together.

Lets equate the sum of the initial charge with the sum of the final for the disk:

q_{1_i} + q_{2_i} = q_{1_f} + q_{2_f} = 2 * (+8.5) \mu C

q_{1_i} + q_{2_i} = +17 \mu C

So, the initial charges must sum +17 μC.

Now, as there are no charges over +17 μC, this means that both charges must be positive.

As the only positive charges are q_C and q_D, this disk must be the ones we are looking for. And, as we can see, they sum 17 μC:

q_{C} + q_{D} = 5 \mu C + 12 \mu C = 17 \mu C
