Question

14 classify each description or equation as either fusion or fission. (4) drag & drop the answer fusion fission in the sun, nuclei of hydrogen atoms are pushed together to form larger helium atoms. in a nuclear power plant, large uranium - 235 nuclei are broken down into smaller elements, and the energy that is released is harnessed for electricity.

$$

Explanation:

Step1: Analyze the first description

In a nuclear power plant, large uranium nuclei are broken down into smaller elements. This is nuclear fission as fission is the splitting of a large nucleus into smaller ones.

Step2: Analyze the first equation

The equation \(_{92}^{235}U+\frac{1}{0}n
ightarrow_{56}^{141}Ba+_{36}^{92}Kr+\frac{1}{0}n\) shows a large uranium nucleus splitting into smaller nuclei (barium and krypton). This is fission.

Step3: Analyze the second description

In the sun, hydrogen atoms are pushed together to form larger helium atoms. This is nuclear fusion as fusion is the combining of small nuclei into a larger one.

Step4: Analyze the second equation

The equation \(_{1}^{2}H + _{1}^{1}H
ightarrow_{2}^{3}He\) shows small hydrogen nuclei combining to form a helium nucleus. This is fusion.

Answer:

Fusion: In the sun, hydrogen atoms are pushed together to form larger helium atoms; \(_{1}^{2}H + _{1}^{1}H
ightarrow_{2}^{3}He\)
Fission: In a nuclear power plant, large uranium nuclei are broken down into smaller elements; \(_{92}^{235}U+\frac{1}{0}n
ightarrow_{56}^{141}Ba+_{36}^{92}Kr+\frac{1}{0}n\)
