Chapter 2: Q2.1-1ITD. (page 29)

Given the makeup of the human body, what compound do you think accounts for the high percentage of oxygen?

Short Answer

Expert verified

Water is a compound responsible for accounting for high oxygen percentage in the human body. This compound can be found in all three states (vapor, solid, as well as liquid).

Step by step solution

01

Compound

The compound is also referred to as a mixture as it consists of two or more elements combined in a particular ratio. One of the examples of compounds is sodium chloride. The common name of sodium chloride is salt.

It is one of the organic compounds that is required by the human body in an essential manner. One of the functions played by sodium chloride (NaCl) in the body is maintaining blood pressure.

02

Water

Water refers to a compound containing a hydrogen atom and an oxygen atom in a particular ratio. These elements are present in a ratio of 2:1, which means that water contains two hydrogen atoms and a single oxygen atom.

The human body is mainly composed of water with a percentage of approximately 60%.The chemical formula associated with water is H2O.

03

Oxygen percentage

Water is composed of two hydrogen atoms and one oxygen atom; however, the mass number of oxygens is comparatively greater than hydrogen. Oxygen is responsible for contributing more to body mass. Thus, water is the main compound that has a high percentage of oxygen.

In Figure 2.7, if two or more elements are in the same row, what do they have in common? If two or more elements are in the same column, what do they have in common?

Female luna moths (Actias luna) attract males by emitting chemical signals that spread through the air. Male hundreds of meters away can detect these molecules and fly towards their source. The sensory organs visible in the photograph are shown here. Each filament of an antenna is equipped with thousands of receptor cells that detect the sex attractant. Based on what you learned in this chapter, propose a hypothesis to account for the ability of a male moth to detect a specific molecule in the presence of many other molecules in the air. What predictions does your hypothesis make? Design an experiment to test one of these predictions.
