They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

4. Which of the following statements accurately compares the wavelengths of the waves shown below?
A) wave 1 has a smaller wavelength than wave 2
B) wave 1 has a larger wavelength than wave 2
C) wave 2 has a larger wavelength than wave 1
D) wave 1 and wave 2 have the same wavelength
Answer:
B. wave 1 has a larger wavelength than wave 2
Wave 1 has larger wavelength than wave 2. Hence, option B is correct.
What is Wavelength?Wavelength is defined as "the difference between two successive crests and troughs of the wave. The wavelength described the how long wave is. It is measure in the direction of wave.
Wavelength is usually denoted by the Greek letter ( λ ).
Wavelength is equal to the speed ( V ) of wave train to divided by frequency ( F ). It is given as,
λ = V ÷ F
Here,
λ = wavelength
V = speed
F = frequency
The distance between one crests (top) to another crests is a Wavelength. Alternately the distance between one troughs (bottom) to another troughs is wavelength.
The distance between two crests in wave 1 is more comparatively wave 2 so , wave 1 will have larger wavelength than wave 2.
Therefore, wavelength is used for measuring the radiation.

True or false? In giant covalent structures the atoms form strong bonds by sharing electrons.
Answer:
True
Explanation:
its true don't lie on here please
In giant covalent structures such as graphite or diamond, the atoms form strong bonds by sharing electrons. Therefore, the given statement is true.
What is a covalent bond?A covalent bond can be defined as a chemical connection formed by the sharing of electron sets between particles. A covalent bond can be created by the mutual sharing of electrons from both atoms.
The pair of electrons that are shared in this kind of bonding is known as the shared or bonding pair. Covalent bonds are the sharing of bonding pairs of electrons that will provide the stability of the atom in its outer shell.
Elements that have very high ionization energies are incapable of exchanging electrons or elements having low electron affinity cannot accept electrons. Covalent bonding between two non-metallic atoms is characterized by the equal sharing of electrons between the atoms and covalent bonds with an electronegativity difference of participating atoms is more than 2.0.
Therefore, a giant structure like a diamond has strong covalent bonds that require a lot of energy to break.

Which elements are the most reactive and why?
Answer:
Fluorine is identified as the most reactive nonmetal and the most electro-negative element in the periodic table, making it the strongest oxidizing agent. Caesium is the most reactive metal in the periodic table, so much that working with this metal often ends in explosions!
Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.

A. 1 mole of any element contains 6.0221 x 1023 _____
B. 1 mole of any compound contains 6.0221 x 1023 ______
Answer:
Explanation:
Taking into account the definition of Avogadro's Number, the correct answers are:
1 mole of any element contains 6.023×10²³ atoms
1 mole of any compound contains 6.023×10²³ molecules
You have to know that Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole.
Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression.
Avogadro's number applies to any substance, because the number of elementary units in a mole of a substance is, by definition, a constant that does not depend on the material or the type of particle considered.
So, in this case, the correct answers are:
1 mole of any element contains 6.023×10²³ atoms
1 mole of any compound contains 6.023×10²³ molecules
