Answer:
Bonding in chemistry is known as chemical bonding which means the interaction or attraction between molecules.
Chemical bonds are of different type such as ionic, covalent, hydrogen, and metallic. Ionic bonds are formed by the transfer of valence electron from one atom to other and there is unequal distribution of electrons between two or more atoms. Ionic bonds forms two oppositely charges ions positively charged (loses electron) or negatively charged (gains electron).
Covalent bond are the strong chemical bonds that form due to equal sharing of electron pairs between atoms. They form a stable element and have stable attraction or repulsive forces.
The reason people describe water as a universal solvent is because it dissolves almost anything.
75.0 mL in liters:
75.0 / 1000 => 0.075 L
1 mole -------------------- 22.4 L ( at STP)
( moles Hg) ------------- 0.075 L
moles Hg = 0.075 x 1 / 22.4
moles = 0.075 / 22.4
= 0.00334 moles of Hg
Hg => 200.59 u
1 mole Hg ----------------- 200.59 g
<span>0.00334 moles Hg ----- ( mass Hg )
</span>
mass Hg = 200.59 x 0.00334 / 1
mass Hg = 0.6699 / 1
= 0.6699 g of Hg
<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.
H is positive 1 and o is negative 2 so 3+b-6=0 and solve for b to get b=3
