The correct answer of the given question above would be option B. IRON 0.449. Based on the given details above about an unknown substance that has a mass of 14.7 g and the substance absorbs 1.323×102 J of heat, the temperature of the substance is raised from 25.0 ∘C to45.0 ∘C, most likely, the substance is IRON. Hope this answers the question.
Use the periodic table , it should be the long decimal if u look it up
For #1 the answer is dependent relationship . 2. answer is independent relationship . the last question the answer is dependent.
its B on plato .. ... . .. . . . . . . ..
<u>Answer:</u> The nuclear equation for the conversion of He-3 nuclide to He-4 nuclide is given above.
<u>Explanation:</u>
Nuclear reaction are defined as the reactions in which nucleus of an atom is involved.
Positron emission is defined as the emission process in which positron particle is emitted. In this process, a proton gets converted to neutron and an electron neutrino particle.

The chemical equation for the reaction of He-3 with a proton follows:

Hence, the nuclear equation for the conversion of He-3 nuclide to He-4 nuclide is given above.
