Answer:
c.
Explanation:
A serial dilution is a dilution that is made fractionated. The stock solution is diluted, then this now solution is diluted, and then successively. The final dilution is the multiplication of the steps dilutions.
The representation of the dilution is v/v (volume per volume) indicates how much of the stock solution is in the total volume of the solution. So 1/5 indicates 1 mL to 5 mL of the solution. If the final volume must be 1 mL, then the stock solution must be 0.2 mL (0.2/1 = 1/5), and the volume of the solvent is 1 mL - 0.2 = 0.8 mL.
The second solution is done with a dilution of 1/10 or 1 mL of the first solution in 10 mL of the total solution. Because the solution has 1 mL, then the volume of the first solution must be 0.1 mL (0.1/1 = 1/10), and the volume of the solvent that must be added is 1 mL - 0.1 mL = 0.9 mL.
Answer: Hydrochloric acid poses a various health risk
Answer:
2
Explanation:
In the equation, Cl is chlorine and there is a number "2" so that the correct answer is 2.
13.82 g / 180.16 g/mol = .07671 moles
.07671 moles / (86.18 g / 1000 g/kg) = .8901 molal

The substitution product that is suppose to be favoured is The product with retention of configuration is expected to predominate slightly, because the leaving group blocks the nucleophile.
<h3>What is substitution product?</h3>
Substitution product is a product that is gotten from a reaction in which a group of reactant is replaced by another group in the reaction.
Therefore,The substitution product that is suppose to be favoured is The product with retention of configuration is expected to predominate slightly, because the leaving group blocks the nucleophile.
