Diamond is composed of hexagonal rings in which sp3 hybridized carbon atoms are linked together.
Hybridization refers to the mixing of atomic orbitals to yield hybrid orbitals that are suitable for bonding. The energy of orbitals that combine to form hybrid orbitals must be close enough for such combination to take place.
Diamond is composed of hexagonal rings in which sp3 hbridized carbon atoms are linked together. Each carbon atom in diamond is tetrahedral.

The reaction that should be followed is
Na2SO4 + C<span>a(NO3)2 --> CaSO4 + 2NaNO3</span>
first calculate the limiting reactant
mol Na2SO4 = 0.075 L (<span>1.54×10−2 mol / L) = 1.155x10-3 mol
mol Ca(NO3)2 = 0.075 L (</span><span>1.22×10−2 mol / L) = 9.15x10-4 mol
so the limiting reactant is the Ca(NO3)2
so all of the Ca2+ will be precipitated, percentage unprecipitated = 0.00 % </span>
Answer:
chlorine gas, sodium hydroxide, and hydrogen gas
Explanation:
The electrolysis of the sodium chloride NaCl solution (brine) will produce chlorine Cl₂ gas and solid sodium Na.
After that, because the reaction takes place in water solution, metallic sodium will react with water forming sodium hydroxide and hydrogen gas.
Na + H₂O → NaOH + H₂
2Na(g) + Cl2(g) 2NaCl(s) is the redox reaction. Na atoms lose electrons and Cl atoms gain electrons, thereby getting oxidized and reduced respectively and fulfilling the requirement of a redox reaction.
