Solve for t In(A/B) -kt where B-1.65 x 102 M A 1.00 x 10 M. k-4.80 x 104s* and t=

myrzilka [38]

Answer:

$t=5.84\times 10^{-5}s$

Explanation:

First rearrange the whole equation by keeping t in one side and rest parameters in another side of equation
Then plug-in all the given values for each parameters and get the solution

$ln(\frac{A}{B})=-kt$

or, $t=\frac{1}{-k}\times ln(\frac{A}{B})$

Now plug-in all given values:

$t=\frac{1}{-4.80\times 10^{4}s^{-1}}\times ln(\frac{1.00\times 10M}{1.65\times 10^{2}M})$

So, $t=5.84\times 10^{-5}s$

Which of the following best describes a fission reaction involving lithium? (1 point)

Feliz [49]

Answer:

D. The nucleus of an atom of lithium splits, resulting in smaller fragments and the release of a large amount of energy.

Explanation:

Fission is the splitting of a nucleus, so this is the only option that involves fission.

A is wrong. Li atoms do not bond to form molecules. Instead, the nuclei are immersed in a sea of electrons.

B is wrong. The joining of two nuclei is fusion.

C is wrong. Adding an electron to an atom of lithium is not a nuclear reaction.
