Answer:

It is a triglyceride

Explanation:

A triglyceride is a molecule that contains a glycerol group and three fatty acids linked by an ester linkage. A fatty acid is a molecule formed by a long linear hydrocarbon chain, of different length or number of carbon atoms, at the end of which is a carboxyl group. These chains can be saturated (with hydrogen) or when there are double bonds in the chain this reduces the available places of hydrogen that's why it's called unsaturated.

In the image you can see on the right the glycerol group. And the three fatty acids extending to the left. The top one is an example of a saturated fatty acid, and the two below unsaturated.

Triglycerides are generally solid at room temperature and are therefore called fats. For example, the fat that constitutes us is mostly formed by triglycerides.

What kind of bonds involve a transfer of electrons? what kind of bond involves sharing of electrons?

Ray Of Light [21]

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

If an acid is made from the anion SO42-, what would it's formula be?

KatRina [158]

Answer: The chemical formula of the compound formed is $H_2SO_4$

Explanation:

Acids are defined as the chemical species which donate hydrogen ions when dissolved in water.

$HA(aq.)\rightarrow H^+(aq.)+A^-(aq.)$

Ionic compound is formed by the complete transfer of electrons from 1 atom to another atom. The cation is formed by the loss of electrons by metals and anions are formed by gain of electrons by non metals.

We are given:

An anion having chemical formula $SO_4^{2-}$ named as sulfate ion

This will combine with 2 hydrogen ions to form a neutral compound. The neutral compound formed is sulfuric acid.

Hence, the chemical formula of the compound formed is $H_2SO_4$
