5 0

Answer:

We will have zero bonds

Explanation:

In this case, we have to start with the structure of 4,5-diethyloctane. This name ends with the suffix "ane" therefore we have an alkane. All the alkanes are made with single bonds between carbons and single bonds between carbon and hydrogen.

The molecule will have a carbon chain of eight carbons and we will have 2 branches, one ethyl on carbon 4 and another ethyl on carbon 5. (see figure 1)

Answer:

1455.6

Explanation: you first convert 2250ml to l by dividing by 1000 so you get 2.25l then you use Boyles law which is p1v1=p2v2 then insert values

35.75*100=p2*2.25 then divide both sides by 2.25 then you get 1455.6

Naya [18.7K]

Answer:

Part A: 36 MBq; Part B: 18 MBq

Explanation:

The half-life is the time it takes for half the substance to disappear.

The activity decreases by half every half-life

A =Ao(½)^n, where n is the number of half-lives.

Part A

3.0 da = 1 half-life

A = Ao(½) = ½ × 72 MBq = 36 MBq

Part B

6.0 da = 2 half-lives

A = Ao(½)^2 = ¼ × 72 MBq = 18 MBq

Name the following compound. Group of answer choices 2-methyl-4-pentyne 4-methyl-3-propyl-1-pentyne 3-isopropyl-1-hexyne 1-nonyn

Fynjy0 [20]

The question is incomplete, the complete question is shown in the image attached

Answer:

3-isopropyl-1-hexyne

Explanation:

Organic compounds can be named from the structure of the compound. The name reveals the arrangement of atoms and bonds in the molecule.

If we look at the compound in the question, we will notice that the parent chain contains six carbon atoms, the triple bond is located at position 1 and the isopropyl substituent is attached to carbon 3.

Hence the proper name of the compound becomes, 3-isopropyl-1-hexyne.
