Answer:
Explanation:
Hello!
In this case, since the molarity of magnesium chloride (molar mass = 95.211 g/mol) is 1.672 mol/L and we know the density of the solution, we can first compute the concentration in g/L as shown below:
Next, since the density of the solution is 1.137 g/mL, we can compute the concentration in g/g as shown below:
Which is also the by-mass fraction and in percent it turns out:
Best regards!

Answer:
When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.
Answer:
SN2 mechanism
Explanation:
This is a situation were substitution occurs with inversion of configuration at the chiral centers which proceed through concerted backside attack where nucleophile approaches the alkyl halides 180° from c-br bond, as c-(nucleophile) bond forms , the c -(leaving group) bond breaks.
