Answer 2

Answer:

Final answer:

Water (H₂O) is an example of a covalent bond, where hydrogen and oxygen atoms share electrons to form a molecule. It is also a polar molecule and commonly acts as a solvent. Water is central in various scales of biological and environmental structures and processes.

Explanation:

Water, or H₂O, is an example of a covalent bond formation. This occurs when hydrogen and oxygen atoms join together, sharing electrons to fill their outer shells and create stability. This sharing of electrons forms a water molecule.

Furthermore, water is considered a polar molecule. Aside from covalent bonding, another characteristic of water is its ability to act as a solvent. It can dissolve gases, liquids, and solids to create different solutions, which is vital in many biological and chemical processes.

A representation of this can be seen from a hydrogen atom, to a water molecule, skin cell, liver, larger organisms like an elephant, wolf pack, up to larger ecosystems like tropical rainforests and the entire planet Earth, indicating the wide scope where water plays a crucial role.

For any given reaction, which of the following will speed up the reaction rate? a)increase the temperature
b)add a catalyst
c)increase the surface area
d)All of the choices are correct.
e)None of the choices are correct.

Answers

All of the choices are correct. Catalysts increase reaction rate by lowering the activation energy of a reaction. When you increase both the temperature and surface area you are just increasing the number of collisions which also increases the reaction rate since the reaction happens when molecules or atoms collide in the correct orientation and with enough energy and you are increasing the number of times that happens in a given time period.

One problem with using pesticides to control insects on crops is that the insects can develop resistance to the chemicals. How is this similar to the overuse of antibiotics?

Answers

Answer:

Explanation:

Overuse of antibiotics leads to bacteria's resistance against our drugs. This is increasing at an alarming rate and the reason is that overuse of antibiotics kills bacteria that lack the "resistance" gene or gene that can help them survive the antibiotics (similar is the case for insects that die to insecticides). But, some bacteria can have random mutations in their gene that can help them survive the antibiotic (similar is the case for some insects that can survive the insecticide), thus the surviving bacteria give rise to next generation of bacteria that are resistant to the given antibiotic (similar to how insects that survive the insecticide give birth to new insects that are resistant to insecticide too). Soon, every generation adds new antibiotic resistant bacteria (or new insecticide resistant insects in the case of insects) which is dangerous for all of life on this planet. Therefore, both are similar in the sense that new generations of these organisms will be resistant to our weapons against them.

What is the total mass of oxygen in 1.00 mole of Al2(CrO4)3

Answers

1 mol of this atom would yield 12 moles of Oxygen, (using the number of atoms that they gave in 1 molecule of Al2(CrO4)3. Therefore, the atomic mass of Oxygen is 16, and there are 12 moles of Oxygen atoms. In total, the mass would be 12 * 16 = 192 grams of Oxygen.

Final answer:

The compound Al2(CrO4)3 contains 12 oxygen atoms per formula unit. Knowing that one mole of oxygen atoms has a mass of 16.00 grams, the total mass of oxygen in 1.00 mole of Al2(CrO4)3 is $12 * 16.00 = 192.00$ grams.

Explanation:

The primary task here is to find the total mass of oxygen in 1.00 mole of Al2(CrO4)3. This is a classic chemistry problem that involves understanding the composition and molar mass of compounds. In the compound Al2(CrO4)3, the subscript 3 after (CrO4) means there are three chrome tetraoxides in one formula unit of the compound.

Every CrO4 ion is composed of one chromium atom and four oxygen atoms. Therefore, three CrO4 ions will contain 3 * 4 = 12 oxygen atoms.

Knowing that one mole of oxygen atoms weighs approximately 16.00 grams, we can find the total mass of oxygen in the compound by multiplying this molar mass by the number of oxygen atoms. Again, in one mole of Al2(CrO4)3 we have 12 oxygen atoms, hence $12 * 16.00 g = 192.00$ grams.
