Question

raj is trying to make a diagram to show what he has learned about nuclear fusion.
diagram: he + energy → h (two) + heat + pressure
is his diagram correct, and if not, how could he fix it?
(option 1: yes, he should leave it as is because one atom of he plus energy results in two atoms of h and heat and pressure)
(option 2: no, he should place energy on the right and heat and pressure on the left.)
(option 3: no, he should place the he atom and energy on the right, and the h atoms and heat and pressure on the left.)
(option 4: no, he should place the he atom on the right and the h atoms on the left.)

Explanation:

Nuclear fusion is a reaction where light hydrogen (H) nuclei combine into a heavier helium (He) nucleus. High heat and pressure are required as input conditions to initiate the fusion, and the reaction releases large amounts of energy as output. Raj's diagram reverses the reactants, products, and energy flow. The correct setup has H atoms + heat/pressure (inputs) on the left, and He + energy (outputs) on the right. The option that matches this correction swaps the positions of He and H, and also places energy on the right, heat/pressure on the left.

Answer:

No, he should place energy on the right and heat and pressure on the left.
No, he should place the He atom on the right and the H atoms on the left.
