Which reaction takes place in a nuclear fission reactor?
Superscript 13 subscript 6 upper C plus superscript 1 subscript 1 upper H right arrow superscript 14 subscript 7 upper N.
Superscript 239 subscript 94 upper P u plus superscript 4 subscript 2 upper H e right arrow superscript 242 subscript 96 upper C m.
Superscript 59 subscript 27 upper C o plus superscript 4 subscript 2 upper H e right arrow superscript 60 subscript 27 upper C o plus superscript 1 subscript 0 n.
Superscript 235 subscript 90 upper U plus superscript 1 subscript 0 n right arrow superscript 94 subscript 36 upper K r plus superscript 139 subscript 56 upper B a plus 3 superscript 1 subscript 0 n.

It's B

Explanation:

In a fission reaction, a larger nucleus is split into two more stable nuclei.

Guys its D?

Explanation:

It is the one with U + n -> Kr + Ba + n

for me its D

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
