Question

choose which statements are true and which statements are false regarding water and its unique characteristics: water is the most abundant molecule in living organisms water is an inorganic molecule because it does not contain hydrogen atoms. in water, electrons spend more time circling the oxygen atom. water makes up about 40 - 50% of the total body weight.

Explanation:

1. Water is indeed the most abundant molecule in living organisms, making up a large - part of cells and bodily fluids.
2. Water is an inorganic molecule but it contains hydrogen atoms (its formula is H₂O). So the statement about it not containing hydrogen atoms is false.
3. In a water molecule, oxygen is more electronegative than hydrogen, so electrons spend more time around the oxygen atom, creating a polar molecule.
4. Water makes up about 60% of the total body weight in adults on average, not 40 - 50%. So this statement is false.

Answer:

TRUE: Water is the most abundant molecule in living organisms; In water, electrons spend more time circling the oxygen atom.
FALSE: Water is an inorganic molecule because it does not contain hydrogen atoms; Water makes up about 40 - 50% of the total body weight.
