Answer:
The rule states that for a given electron configuration, the lowest energy term is the one with the greatest value of spin multiplicity. This implies that if two or more orbitals of equal energy are available, electrons will occupy them singly before filling them in pair

What mass does 4.41 moles of cobalt have? Help!!!!
Answer:
260 g
Explanation:
Data obtained from the question include:
Mole of cobalt (Co) = 4.41 moles
Mass of cobalt (Co) =...?
The mole of a substance is related to its mass according to the following equation:
Mole = mass / Molar mass.
With the above formula, we can obtain the mass of 4.41 moles of cobalt as follow:
Mole of cobalt (Co) = 4.41 moles
Molar mass of cobalt = 59 g/mol
Mass of cobalt (Co) =...?
Mole = mass /Molar
4.41 = mass / 59
Cross multiply
Mass of cobalt = 4.41 × 59
Mass of cobalt = 260 g
Therefore, the mass of 4.41 moles of cobalt is 260 g

Express 749 000 000 in scientific notation,
Answer:
7.49 × 108
Explanation:
Scientific notation is a way to express numbers in a form that makes numbers that are too small or too large more convenient to write. It is commonly used in mathematics, engineering, and science, as it can help simplify arithmetic operations. In scientific notation, numbers are written as a base, b, referred to as the significant, multiplied by 10 raised to an integer exponent, n, which is referred to as the order of magnitude:

what happens to the molecules as water freezes PLS HELP THIS IS DO TODAY
During freezing, water molecules lose energy and do not vibrate or move around as vigorously. This allows more stable hydrogen-bonds to form between water molecules, as there is less energy to break the bonds. ... Thus water expands as it freezes, and ice floats atop water.
When water molecule freezes, the water molecules have slowed down enough that their attractions fixed them into fixed positions.
What do you mean by freezing ?The term freezing is defined as a phase transition where a liquid converted into a solid when its temperature is lowered below its freezing point.
The freezing point is the temperature at which a liquid turns solid. In the freezer, for example, water-filled ice cube trays.
Water molecules freeze in a hexagonal pattern, with molecules further apart than when the water was liquid. It is worth noting that the molecules in ice would be vibrating.
Thus, When water freezes, the water molecules slow down to the point where their attractions arrange them into fixed positions.

It is incorrect because it should have a total of eight electrons with two electrons between each H and O
Further explanationLewis structure shows the form of bonds that occur in the valence electrons of an element or compound
This bonding usually occurs in covalent bonds
Valence electrons are electrons used in a chemical bond
The main group elements usually have valence electron configurations in the ns and np subshells, While the transition elements in the subshells (n-1) d and ns.
Element O has 6 valence electrons
Element H has 1 valence electron
To achieve stability, the element O needs 2 more electrons which are obtained from 2 electrons from the H element, while the H element needs 1 electron to be stable
So that a covalent bond is formed

D.Gains energy by eating other living things
Answer:
Gains energy by eating other living things
The statement 'gains energy by eating other living things' is a characteristic shared by both primary and secondary consumers (Option D).
Producers (e.g. algae and plants) are autotrophic organisms that generate their own food.Primary consumers and secondary consumers are heterotrophs that need to eat other organisms to survive.Primary consumers can be, for example, herbivores, whereas secondary consumers can be carnivores.In conclusion, the statement 'gains energy by eating other living things' is a characteristic shared by both primary and secondary consumers (Option D).

If carbon monoxide (CO) leaked into your home, would you predict that if would float to the
top of the room or stay near the floor? Answer the same question for carbon dioxide (CO2),
would it float or sink?
Answer: It will sink
Explanation:
To solve this we must be knowing each and every concept related to carbon monoxide. Therefore, carbon monoxide float to the top of the room.
What is carbon monoxide?When the carbon in fuels burns inefficiently, a toxic gas known as carbon monoxide is created. It is emitted both naturally—from forest fires or volcanic eruptions, for example—and artificially—through procedures. It is lighter than the air.
By attaching to and removing oxygen from myoglobin, carbon monoxide reduces the oxygen storage capacity in muscle cells, which is another way it upsets the body's processes. If carbon monoxide (CO) leaked into your home, carbon monoxide float to the top of the room. Numerous manufacturing and medicinal items employ carbon monoxide.
Therefore, carbon monoxide float to the top of the room.
