Which of the following is composed of organic compounds?

2 answers:

3 0

The best answer would be HUMANS.

This is because organic compounds are essentially carbon based compounds and the human body is made up of many such compounds such as the protein that makes up skin, hair, nails, hormones and enzymes; gylcoproteins that are essential for cell membrane; fat found in skin and other tissues.

Answer:

Humans

Explanation:

Organic compounds are molecules that are present in living systems. These are mainly characterised by the presence of carbon (C) atoms which are linked together in the form of linear chains or arranged in ring like structures. In addition to carbon, organic compounds also contain other atoms like hydrogen (H), oxygen (O), nitrogen(N) and sulfur (S).

The human body is mainly composed of organic compounds like proteins, lipids, amino acids, sugars and carbohydrates.

Based on the chemical equation, use the drop-down menu to choose the coefficients that will balance the chemical equation: ()zn

Bingel [31]

Based on the chemical equation, to balance the equation we use 2 as a coefficients of HCl on left hand side of reaction.

<h3>What is balanced equation?</h3>

Balanced chemical equations are those equation in which each entities are present in same amount on left side as well as on the right side of the chemical reaction.

Given chemical reaction is:

Zn + HCl → ZnCl₂ + H₂

Above reaction is not balanced equation as number of chlorine and hydrogen atoms are not same, so balanced equation will be:

Zn + 2HCl → ZnCl₂ + H₂

Hence we add 2 as a coefficient of HCl to balance the equation.

Which of these takes place when a chemical change occurs? option 1: Bonds connecting atoms in products and reactants form. optio

Tamiku [17]

Answer: Out of the given options bonds connecting atoms in reactants break, and bonds connecting atoms in products form are the changes which takes place when a chemical change occurs.

Explanation:

A change that leads to the change in chemical composition of a substance is called a chemical change.

For example, $2NH_{3} \rightarrow N_{2} + 3H_{2}$

Here, bond between the reactant atoms nitrogen and hydrogen is broken down.

On the other hand, bond connecting the products that is $N_{2}$ and $H_{2}$ is formed.

Thus,, we can conclude that out of the given options bonds connecting atoms in reactants break, and bonds connecting atoms in products form are the changes which takes place when a chemical change occurs.
