Answer:

94.6% yield

Explanation:

$25.0 g CS2 (\frac{1 mol CS2}{76 g CS2}) (\frac{2 mol SO2}{1 mol CS2} ) (\frac{64 g SO2}{1 mol SO2} ) = 42.8 g SO2$

42.8 g SO2 -> 100% yield

40.5 g SO2 -> x

x= (40.5 g SO2 * 100)/42.8 g SO2 x=94.6%

Spell out the full name of the compound.

Talja [164]

Answer:

2–methyl–3–propylheptane.

Explanation:

The name of the compound can be obtained as follow:

1. Identify the functional group of the compound.

2. Determine the name of the compound by determining the longest continuous carbon chain.

3. Identify the substituent group attached.

4. Locate the position of the substituent group by giving it the lowest possible count. Where there are two or more different substitutent group attached to the compound, name them alphabetically.

5. Name the compound by combining

the above steps.

Thus, we can name the compound as follow:

1. The compound has only single bond. Therefore, the compound is an alkane.

2. The longest continuous carbon chain is 7. Therefore, the parent name of the compound is heptane.

3. The substitutent groups attached are:

Propyl i.e –C3H7

Methyl i.e –CH3

4. The substituent groups are located at:

Propyl i.e –C3H7 is located at carbon 3.

Methyl i.e –CH3 is located at carbon 2.

5. The name of the compound is:

2–methyl–3–propylheptane.

How many grams of material is lost in the aqueous phase if two extractions are carried out on 100 mL of a 5% (m/v) aqueous solut

san4es73 [151]

Answer:

4.94g of material

Explanation:

Partition coefficient (Kp) of a substance is defined as the ratio between concentration of organic solution and aqueous solution, that is:

Kp = 8 = Concentration in Ethyl acetate / Concentration in water

100mL of a 5% solution contains 5g of material in 100mL of water. Thus:

8 = X / 100mL / (5g-X) / 100mL

Where X is the amount of material in grams that comes to the organic phase.

8 = X / 100mL / (5g-X) / 100mL

8 = 100X / (500-100X)

4000 - 800X = 100X

4000 = 900X

4.44g = X

Thus, in the first extraction you will lost 4.44g of material from the aqueous phase.

And will remain 5g-4.44g = 0.56g.

In the second extraction:

8 = X / 100mL / (0.56g-X) / 100mL

8 = 100X / (56-100X)

448 - 800X = 100X

448 = 900X

0.50g = X

In the second extraction, you will extract 0.50g of material

Thus, after the two extraction you will lost:

4.44g + 0.50g = 4.94g of material

A (green), B (blue), and C (red) are structural isomers. The molecular filmstrip depicts them undergoing a chemical change as ti

agasfer [191]

The geometric arrangement of one of two or more compounds that have the same number and type of atoms but differ drastically from one another.

<h3>What is structural isomers?</h3>

The term "structural isomer," also known as a "constitutional isomer," refers to a group of two or more organic compounds that share the same chemical formula but have different structures. In spite of having the identical chemical formula, the two molecules below differ in where the methyl group is located.

The most extreme kind of isomerism is structural isomerism. As contrast to stereoisomerism, which merely differs in the relative spatial arrangement of the atoms while maintaining the identical atoms and bonding structure. The enantiomers, which have molecules that are mirror images of one another, and the cis and trans forms of 2-butene are examples of the latter.

Skeletal isomers, positional isomers (also known as regioisomers), functional isomers, tautomers, and structural topoisomers are some of the different classes of structural isomers.
