Answer:

Option D is the answer

D. a mixture of diastereomers formed in unequal amounts.

Explanation:

Chiral intermediates give chiral products

- form unequal mixtures of diastereomers

- transition states are now diastereotopic

• Optically active reactants leads to optically active products.

For the chemical reaction, Li + NaCl <-- --> Na + LiCl, the rate law would be...
Amiraneli [1.4K]

<u>Answer:</u> The rate law for the given chemical equation is \text{Rate}=k[Li][NaCl]

<u>Explanation:</u>

Rate law is defined as the expression that expresses the rate of the reaction in terms of the molar concentration of all the reactants each term raised to the power their stoichiometric coefficient in the given balanced chemical equation.

For the given balanced chemical equation:

Li+NaCl\rightleftharpoons Na+LiCl

Rate law expression for the reaction:

\text{Rate}=k[Li][NaCl]

Order with respect to Li = 1

Order with respect to NaCl = 1

Hence, the rate law for the given chemical equation is \text{Rate}=k[Li][NaCl]

Answer:

<h2>70.27 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L}  \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{4.23 \times  {10}^{25} }{6.02 \times  {10}^{23} }  \\  = 70.265780...

We have the final answer as

<h3>70.27 moles</h3>

Hope this helps you

a 9.56g sample of CuS is found to contain 6.35g of copper. What is the percent by mass of sulfur in this compound? Report your a
Volgvan

Answer:

33.58%

Explanation:

Data obtained from the question include:

Mass of CuS = 9.56g

Mass of Cu = 6.35g

Mass of S = Mass of CuS — Mass and Cu

Mass of S = 9.56 — 6.35

Mass of S = 3.21g

The percentage by mass of sulphur in CuS is given by:

Mass of S/mass of CuS x 100

Percentage by mass of S = 3.21/9.56 x 100 = 33.58%

IRINA_888 [86]

Answer:

A compound

Explanation:

The water is best classified as a compound. When a substance is broken down into elemental composition or units, they are said to be a compound.

  • An element is a distinct substance that cannot be split up into simpler substances.
  • Compound are substances composed of two or more kinds of atoms  joined together in a definite grouping.
  • The properties of compounds are distinct and different from those of the individual elements that are combined in its make - up.
  • So, the water when broken down to elements is a compound.
