<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.
![_Z^A\textrm{X}\rightarrow _{Z-1}^A\textrm{Y}+_{+1}^0e](https://tex.z-dn.net/?f=_Z%5EA%5Ctextrm%7BX%7D%5Crightarrow%20_%7BZ-1%7D%5EA%5Ctextrm%7BY%7D%2B_%7B%2B1%7D%5E0e)
The chemical equation for the reaction of He-3 with a proton follows:
![_2^3\textrm{He}+_1^1\textrm{H}\rightarrow _2^4\textrm{He}+_{+1}^0e](https://tex.z-dn.net/?f=_2%5E3%5Ctextrm%7BHe%7D%2B_1%5E1%5Ctextrm%7BH%7D%5Crightarrow%20_2%5E4%5Ctextrm%7BHe%7D%2B_%7B%2B1%7D%5E0e)
Hence, the nuclear equation for the conversion of He-3 nuclide to He-4 nuclide is given above.
The specific heat capacity the substance is calculated using the below formula
Q(heat) = Mc delta T
Q =1560 cal
m(mass) 312 g
delta T (change in temperature ) = 15 c
C= specific heat capacity=?
by making c the subject of the formula
c=Q/m delta T
= 1560 cal/ 312g x 15 c = 0.33 cal/g/c (answer B)
The density of a 167.4 g sample of magnesium having a volume of 96.32 ml is <u>1.737 g/cm3.</u>
<h3>What is density?</h3>
The mass per unit volume is known as density. A scalar quantity, density. It is represented by the letter D, and the Greek letter rho is used as the sign for density. Mass divided by volume is how density is computed.
Mass is a physical body's total amount of matter. Mass is defined as the sum of the moles of the material and the compound's molar mass.
Given the mass is 167.4 g
The volume is 96.32 ml
mass / volume
167.4 / 96.32 = 1.737
Thus, the density of a 167.4 g sample of magnesium is 1.737 g/cm3.

Answer:
each of more than one hundred substances that cannot be chemically interconverted or broken down into simpler substances and are primary constituents of matter. Each element is distinguished by its atomic number, i.e. the number of protons in the nuclei of its atoms.
