<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.
Answer: -
81.03 g magnesium oxide is formed when 48.62g of magnesium is reacted with excess oxygen
Explanation: -
Atomic mass of Mg = 24 g
Molar mass of MgO = 24 x 1 + 16 x 1
= 40 g
The balanced chemical equation for this reaction is
2 Mg + O₂ → 2MgO
From the balanced chemical equation we see
2 mol of Mg gives 2 mol of MgO.
2 x 24 g of Mg gives 2 x 40g of MgO.
48.62 g of Mg gives x Mg
= 81.03g of MgO
