The electronic configuration of the carbon atom is written as: 1s²2s²2p². Each s orbital can hold up to 2 electrons, while each p orbital hold up to 6 electrons. That means that the first two shells are closed, while the 4 electrons in the p-orbital is open. The 4 valence electrons of the carbon can bond with many other element, including carbon itself. This unique property is called catenation. That is why one borad field of chemistry, called organic chemistry, is dedicated solely to compounds containing carbon.

Explanation:
Triglycerides are special type of lipids. They are formed by glycerol with three fatty acid chains. The fatty acid chains can vary in length, they can be saturated or unsaturated with varying composition. It is the most abundant lipid in diet. It is available in plant as well as animal based foods. In case of mammals the triglycerides are stored in the adipose tissue in which they are broken to release energy.
Answer:
See explanation
Explanation:
Potassium is a metal. Remember that metals are electropositive in nature. This implies that they give out electrons when they undergo ionic bonding with nonmetals.
Chlorine is a nonmetal. So the bond between chlorine and potassium is ionic. Potassium gives out one electron to chlorine and the both ions now attain a stable octet.
The electronic configuration of potassium is [Ar]4s1. After giving out an electron to chlorine in an ionic bond, its electronic configuration is now [Ar].
The density of the carbon tetrachloride is 1.59 g/mL.
Mass of CCl₄ = 703.55 g – 345.8 g = 357.75 g
Density = mass/volume = 357.75 g/225 mL = 1.59 g/mL
