Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of the drawing referred to in the question.
However, each option refers to a particular respiratory system and with the organs and the tissues mentioned here one can eventually identify which option is correct when the drawing is available.
A) The system described here is the cardiovascular system (or the circulatory system). This system involves the heart, blood vessels and the blood (which are what help in the transport of the materials mentioned in the question).
B) The system described here is the digestive system. This system involves the gastrointestinal tract and organs (that assist in the production/secretion or storage of chemicals that breakdown food into smaller pieces) such as the mouth, esophagus, stomach, small intestine, large intestine, rectum and the anus.
C) The system described here is the skeletal system. This system involves all the bones and joint in the body (the skeleton) which also helps in protecting organs in the body.
D) The system described here is the Endocrine system. This system involves several internal glands (such as the thyroid gland and the adrenal glands) in the body.
NOTE: Identify which organ and/or tissue is present in the diagram and use that to select the appropriate option from the description of each of the options provided above.

Answer:
In conclussion, 0.60 moles of HCOOH contains the greatest mass of O
Explanation:
Let's make some rules of three, to solve this problem:
1 mol of ethanol has 2 moles of C, 6 moles of H, and 1 mol of oxygen
Therefore, 0.75 moles of ethanol must have 0.75 mol of oyxgen
Let's convert the moles to mass → 0.75 mol . 16 g/ 1 mol = 12 g
1 mol of formic acid has 2 moles of H, 1 mol of C and 2 mol of oxygen
0.60 moles of formic acid must have (0.6 .2) / 1 = 1.2 mol of O
If we convert the amount to mass → 1.2 mol . 16 g/ 1mol = 19.2 g
1 mol of water has 1 mol of oyxgen
Therefore, we have 1 mol of oxygen with a mass of 16 g.
In conclussion, 0.60 moles of HCOOH contains the greatest mass of O
A meteorologist predicts fog in the morning over lakes and river bottoms because of the atmospheric conditions and their interactions with the <span>hydrosphere. The hydrosphere is the region on the Earth's surface where the total water on the planet is found. The hydrosphere can be in the form of liquid, vapor, or ice.</span>
