Which equation represents a fission reaction? Superscript 14 subscript 7 upper N plus superscript 1 subscript 1 upper H right arrow superscript 15 subscript 8 upper O. Superscript 235 subscript 92 upper U plus superscript 1 subscript 0 n right arrow superscript 140 subscript 55 upper C s plus superscript 94 subscript 37 upper R b plus 2 superscript 1 subscript 0 n. Superscript 9 subscript 4 upper B e plus superscript 4 subscript 2 upper H e right arrow superscript 12 subscript 6 upper C plus superscript 1 subscript 0 n. Superscript 239 subscript 93 upper N p right arrow superscript 239 subscript 94 upper P u plus superscript 0 subscript negative 1 e.

Alpha particles have positive charge, beta particles have negative charge, and answer 4 just doesn’t make sense. thus, you are left with only one possible answer.

I’m pretty sure it’s false i’m not sure

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
