Use the percent as mass in g
Mass g) --> g/mol
K, B and H molar mass from periodic table
54.93 g K x (1 mol K/ 39.10 g K) = 1.405 mol K
38.73 g B x (1 mol B/ 10.81 g B) = 3.583 mol B
6.34 g H x (1 mol H/ 1.008 g H) = 6.290 mol H
Divide all three answers by the smallest value and you will get
1.000 mol K
2.550 mol B
4.477 mol H
now multiply these three answers by a number that will make all a whole number or (a number with a 9 as the first decimal point)
so multiply by 2
2 mol k
5 mol B
and 9 mol H
E.F. = K2B5H9
Answer is D
Sorry for bad explanation!!!!!!
The option that would be appropriate to model nuclear fission is disturbing a drop of water such that it breaks into smaller droplets
Nuclear fission refers to the splitting of a heavy nucleus into lighter nuclei owing to the bombardment of small particle.
The liquid drop model provides the most apt model for describing the concept of nuclear fission. In nuclear fission, the nucleus breaks due to the increase in repulsion between the nuclear charges.
As the size of the nucleus continues to increase, any little disruption will; result in the breaking up of the nucleus into smaller fragment called daughter nuclei.
Hence, the model of disturbing a drop of water such that it breaks into smaller droplets is the most apt description of nuclear fission.

I think is true not sure but it might be
Answer:
It will mess up the orbit around the sun
Explanation:
<span>The atom is the smallest unit of matter of a chemical element that maintains its identity or its properties in smaller particles. Atoms are indestructible and retain their identity in chemical changes. This happens in a chemical reaction and this element is a small particle that supports changes in chemical reactions.</span>
