Compound A melts at 801o C and is soluble
Karo-lina-s [1.5K]

Explanation:

Organic compounds are defined as the compounds which contain carbon as their main element. For example, CH_{3}OH is an organic compound.

Generally, organic compounds are non-polar in nature and due to the presence of covalent bonding organic compounds have low melting point.

As compound A melts at 801^{o}C and is soluble  in water. This means it is an ionic compound as it has high melting point and it is also polar in nature.

Whereas compound B melts at 24^{o}C and is insoluble  in water. This means that this compound has covalent bonding and it is also non-polar in nature . Hence, it is more likely to be organic in nature.

Thus, we can conclude that compound B is more likely to be an organic

compound.

In 100 grams of sweet peas there are 14.5 carbohydrates,5.7 grams of sugars,5.1 grams of dietary fiber, 5.4 grams of protein and
Serjik [45]
Percent composition is the quantity or number of parts of a component contained in 100 parts of the total.

Given the the total is 100 g, the reported quantities for each component are the same percent.

Then, the percent composition of each as part of the entire sweet peas is:

Carb: 14.5%
Sugar: 5.7%
Diet. fiber: 5.1%
Prot: 5.4%
Fat: 0.4%

The rest to make the 100% is supposed to be water.

You could also find the percent composition in dry basis, which is done in this way (this is not what the question asks but it is good to know it).

Total components without water: 14.5 + 5.7 + 5.1 + 5.4 + 0.4 = 31.1 grams

Now divide each content by the total (31.1) and multiply by 100.

I will do one example:

Carbs: [14.5 / 31.1 ] * 100 = 46.6%
