Question

multiple choice 1 point
select the equation that shows fusion.
{}_{92}^{235}u + n \to {}_{56}^{141}ba + {}_{36}^{92}kr + 3n + energy
{}_{1}^{1}h + {}_{1}^{1}n \to {}_{1}^{3}h + energy
{}_{11}^{23}na + cl_{2} \to 2nacl
{}_{11}^{23}na + {}_{1}^{1}h + {}_{1}^{1}h \to 2nah
matching 3 points
match each letter in the diagram with the correct label.

Explanation:

Step1: Understand nuclear fusion

Nuclear fusion is the process where two or more light - nuclei combine to form a heavier nucleus.

Step2: Analyze each equation

• For \(_{1}^{1}H+_{1}^{1}H

ightarrow_{1}^{2}H + energy\), it is a nuclear fusion reaction as two hydrogen - 1 nuclei combine.

• \(_{92}^{235}U + n

ightarrow_{56}^{141}Ba+_{36}^{92}Kr + 3n+energy\) is a nuclear fission reaction (a heavy nucleus splits).

• \(_{11}^{23}Na+_{1}^{1}H

ightarrow2_{6}^{12}C\) is a nuclear reaction, but not the typical simple fusion shown in basic examples.

• \(_{11}^{23}Na+Cl_{2}

ightarrow2NaCl\) is a chemical reaction (not a nuclear reaction).

Answer:

\(_{1}^{1}H+_{1}^{1}H
ightarrow_{1}^{2}H + energy\)
