Answer: nitrogen

Explanation:

Functional groups are specific group of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.

1. Amides have functional group $-O=C-NH_2$ .

Example: Ethanamide with molecular formula $CH_3CONH_2$

2. Amines have functional group $-NH_2$ .

Example: Ethanamine with molecular formula $CH_3CH_2NH_2$

Thus both amines and amides are organic compounds containing the element nitrogen.

Answer:

The key feature of an amine is a nitrogen atom bonded to a carbonyl carbon atom. Like esters, amides are formed in a condensation reaction. ... These polymers are formed from another organic nitrogen compound, the amino acid. These molecules contain both an amine group and a carboxyl group.

Which member of each pair is more soluble in water? Why?<br> (a) CH₃CH₂OCH₂CH₃(l) or CH₃CH₂OCH₂(g)

Anna [14]

CH₃CH₂OCH₂ is more soluble in water because it has shorter hydrocarbon chain.

<h3>What is hydrocarbon?</h3>

Hydrocarbon is defined as the compound which contain hydrocarbon and carbon atoms.

The carbon atom attached to each other to form framework and hydrogen atom attach to them in different ways to give different configuration. One of the most popular hydrocarbon compound is diamond.

<h3>Solubility of hydrocarbon in water</h3>

Hydrocarbon is non polar compound whereas water is polar compound. So, hydrocarbon is in soluble in water. But as they have weak intermolecular interactions known as London dispersion forces i.e. Instantaneous dipole-induced dipole interactions.

make them less soluble in water.

Greater the hydrocarbon chain lesser will be the solubility of ketone in water. On the other hand, lesser the hydrocarbon chain greater will be the solubility of ketone in water.

Thus, we concluded that the CH₃CH₂OCH₂ is more soluble in water because it has shorter hydrocarbon chain.

If 8.6 g of ch4 and 5.9 g of o2 react, what is the mass, in grams, of h2o that is produced?

Alenkasestr [34]

This may seem confusing because they give you two masses, but all you have to do is pick one to do the calculations. Personally, I would pick O2, since the molar mass is easier to calculate. The answer would be 3.3 g (rounded for sig figs). To get this, first take the 5.9 grams of O2 and convert it to moles by dividing by the molar mass of oxygen gas, which is 32. Then, multiply both by the mole-mole ratio, which is 2:2, or simply 1:1. After that, multiply that by 18g, which is the molar mass of water to get grams of water.

REMEMBER, you have to write and balance the chemical equation before you can do any of that work.
That happens to be CH4 + 2O2 => CO2 + 2H2O
