rate 1 of the reaction = k [A]²
rate 2 of the reaction = k [A/2]² = k[A]² /4
We can see that rate of the reaction will be 4 times less.
Answer: Here's your answer: Therefore, the decimal number 0.0020 written in scientific notation is 2 × 10-3 and it has 2 significant figures. Here are some more examples of decimal to scientific notation 0.00200 in scientific notation
Explanation: Pls mark me brainiest pls
Wavelength = (planck’s constant) (speed of light) / Energy
6.2 (Energy) = (6.63 •10^-34) (3•10^8)
1.989•10^-25 / 6.2 =
3.2081 • 10^-26 is the answer
Answer:
I think it's answer would be A
Because some are photoreactive
