Answer:
commission
Explanation:
Employers benefit from paying a commission to their employees because it means that they only pay the employee if there is a sale. ... It also improves the cash flows of the business because it means that employees are only paid when money is coming in from a sale.
If i were a maneger I would love commision For the reason that is stated above, but if I was just an employe I would rather work from tips.

why do gases behave least like ideal gases at low temperature and high pressure?
The ideal gas law fails at low temperature and high-pressure because the volume occupied by the gas is small, therefore the inter-molecular distance between the molecules falls. And hence, an attractive force can be seen between them.
What is ideal gas law ?The ideal gas law states that the pressure, volume, and temperature of a gas are directly proportional to each other, as long as the number of particles and the mass of the gas remain constant. So long as the number of particles and gas mass remain constant.
The ideal gas law can be utilized to calculate the volume of gases produced. The ideal-gas equation often is used to interconvert between volumes and molar amounts in chemical equations.
At high pressures, the molecules of a gas are crowded closer together, and the amount of vacant space between the molecules is reduced.
Thus, gases behave least like ideal gases at low temperature and high pressure.

Answer:
F= -1 (group 7A)
Ca= +2 (group 2)
Explanation:
oxidation #= # electrons atom gains/loses to form chemical bond
>assigned to atoms in oxidation-reduction rxn to indicate ability to donate/ gain e-
> positive oxidation #= loss of e-, negative= gain of e-
rules:
all group 2 elements (ca) have an oxidation state of 2+

If a sample of gas occupies a volume of 6.80 L at 325°C, what will its volume be at
25.0°C if the pressure does not change?
Answer:
3.4L
Explanation:
Given parameters:
Initial Volume of gas = 6.8L
Initial temperature of gas = 325°C = 325 + 273 = 598K
Final temperature = 25°C = 25 + 273 = 298K
Unknown:
Final volume = ?
Solution:
To solve this problem, we apply the Charles's law. It can be expressed as;
[tex]\frac{V1}{T1}[/tex] = [tex]\frac{V2}{T2}[/tex]
V and T are volume and temperature
1 and 2 are initial and final states
Now insert the parameters and solve;
[tex]\frac{6.8}{598}[/tex] = [tex]\frac{V2}{298}[/tex]
2026.4 = 598V2
V2 = 3.4L

The reaction of iron ore with carbon follows the equation: 2 Fe2O3 + 3 C 4 Fe + 3 CO2.
How many grams of Fe can be produced from a mixture of 200. g of Fe2O3 and 300. g of C?
In the above problem, which reactant is limiting and which is in excess?
Answer:
The person writes a coefficient of 2 in front of Fe2O3 but then writes a 4 for the number of iron (Fe) atoms. Explain this difference.
Explanation:
The iron oxide Fe₂O₃ is the limiting reagent while carbon (C) is the excess in the given reaction.
What is the limiting reagent?A limiting reagent can be described as a reactant that is completely exhausted from the reaction mixture at the completion of a reaction and is also named a limiting reactant.
When reactants in the chemical reaction are not taken in stoichiometric quantities, the limiting reactant will determine the maximum amount of product that can be formed in a chemical reaction from the reactants.
Given, a balanced chemical equation of the reaction between iron oxide and carbon is:
[tex]2 Fe_2O_3 + 3 C\longrightarrow 4 Fe + 3 CO_2[/tex]
Given, the amount of the iron oxide = 200 g
The molecular mass of the iron oxide = 159.69 g/mol
The number of moles of iron oxide = 200/159.69 = 1.252
Given the mass of the carbon, = 300 g
The number of moles of carbon = 300/12 = 25
If 2 moles of iron oxide react with carbon moles = 3
1.252 moles of Fe₂O₃ will react with carbon = (3/2) × 1.252 = 1.878 mol
Therefore, Fe₂O₃ is the limiting reactant and carbon is the excess reactant.

Explanation:
Solar energy does not warm Earth’s surface evenly. For example, during the day, land areas warm up faster than nearby bodies of water. How does this uneven warming affect the movement of air over land and water?
Answer:
Land and sea breeze
Explanation:
This uneven warming of the land during the day results in the phenomenon called land and sea breeze.
During the day, the land heats up faster than the nearby ocean. Ocean is made up of water with a high specific heat capacity. This derives pressurized air near the surface of the land to the ocean. At night, the ocean does not easily lose heat after the land has lost its own. Pressurized air moves from the ocean to the land. This causes the warming of the land during the night.Two students were doing an experiment which involved adding potassium sulfate powder to water. They added one teaspoon of potassium sulfate to the water and stirred it, and all the powder dissolved. They continued to do this until, after the fourth teaspoon, no more potassium sulfate would dissolve.
As more potassium sulfate dissolves in the water, the mixture becomes
a. more concentrated.
b. less concentrated.
c. dilute.
d. more cloudy.
Answer:

Explanation:
because it will get dissociated into more ions
what is the name for C3Cl8 and is it a covalent or polar covalent bond?
Answer:
Propane, octachloro- | C3Cl8 - PubChem
The name of C3Cl8 is octachloropropane. It is a covalent bond.
What are covalent bonds ?Covalent bonds are formed when two atoms share electrons. In the case of octachloropropane, the carbon atoms share electrons with the chlorine atoms. The electrons are shared unequally, so the bond is polar covalent.
The name octachloropropane is derived from the Greek words "octo" (eight) and "chloro" (chlorine). The prefix "octa" refers to the number of chlorine atoms in the molecule. The suffix "propane" refers to the three carbon atoms in the molecule.

Three reasons why friction is needed
Answer:
1:Without friction, we would not be able to stop walking since we would just keep slipping like on ice.
2:Without friction, objects would just slip and fall with a simple blow of air
3:And finally, without friction, we wouldn't be able to use machinery like cars and etc since they would just fly off
Explanation:
Friction can be a useful force because it prevents our shoes from slipping on the pavement when we walk and stops car tires skidding on the road. When you walk, friction is caused between the tread on shoes and the ground. This friction acts to grip the ground and prevent sliding. Sometimes we want to reduce friction.

As you move from left to right across the second period of the periodic table
A. Ionization energy increases
B. Atomic mass decreases
C. Electronegativity decreases
D. Atomic radii increase
Answer:
A. ionizing energy increases
A tabular form in which the chemical elements are positioned according to the chemical and physical attributes is called the periodic table. The horizontal rows from left to right is referred as periods in the table.
The correct option is:
Option A. Ionization energy increases
This can be explained as:
The ionization energy raises from left to right because of valence shell resilience.The nuclear charge on the atom expands and protons in the nucleus lure the electrons more strongly.Therefore due to the high proton number, the ionization increases across the period.
