Which macro nutrient is made up of carbon and hydrogen elements join together in long groups called hydrocarbons?

The study of chemicals and their bond is called chemistry.

The correct answer is lipid.

Those molecules which are present in the cell more than the amount of 800 daltons are called macromolecules.

According to the question, the correct answer is lipid because in lipid all the molecules are made up of a long chain of carbon and hydrogen join together.

For example, palmitic is made up of 16 carbon compounds.

Hence, the correct answer is lipid.

organic molecules made up of carbon and hydrogen elements joined together in long groups called hydrocarbons. The arrangement of these hydrocarbon chains, and their interaction with each other, determines fat type.

the atomic mass is the bottom number on the element.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
