Explanation:
Would you rather get tips or a commission for your wages? Why?
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.

How many protons are in the nucleus of one atom of neon based on this information found in the Periodic Table?
Answer:
10 protons
Explanation:
The atomic number of an element is equal to the number of protons of the element. The atomic number of neon is 10. Therefore, neon contains 10 protons.
10 protons are in the nucleus of one atom of neon based on this information found in the Periodic Table.
What is periodic table ?The chemical elements are arranged in rows and columns in the periodic table, sometimes referred to as the periodic table of the elements. It is frequently used in physics, chemistry, and other disciplines and is frequently regarded as a symbol of chemistry.
The elements are organized in what is known as the periodic table. Columns and rows are used to organize the table. The horizontal rows are referred to as "periods," while the vertical columns are known as "groups."
Thus, The atomic number of an element is similar to the number of protons of the element. The atomic number of an element neon is 10. So, neon contains 10 protons.

give me examples of everyday problems you think involve the green substances copper acetate or copper sulfate.
Answer: Copper sulfate is also called blue vitriol, Roman vitriol, Salzburg vitriol, blue copperas or bluestone, which is an inorganic or chemical compound comprised of Copper, Sulphur and Oxygen. It is an odorless crystalline substance, electric blue and highly toxic, which is produced in industries by treating the copper metal with hot concentrated sulfuric acid or treating its oxides with dilute sulfuric acid. It can be produced by slowly leaching low-grade copper ore in air and bacteria may be used to hasten the process.

In the quantum mechanical model, what two words do they use to describe
particles?
Answer:
This question is incomplete
Explanation:
This question is incomplete but one can assume the answer from the definition of quantum mechanics. Quantum mechanics is the science that describes particles in nature at the atomic and subatomic particle (electron, proton and neutron) level. Thus it can be assumed that atoms and subatomic particles are used to broadly describe particles.

Thermal energy is a form of... A. kinetic energy. B. electrical energy. C. potential energy. D. chemical energy.
Answer:
A. Kinetic Energy
Explanation:
Thermal energy is when the molecules and atoms are vibrating faster due to higher temperatures.
Kinetic energy fits this because the meaning of it is the energy of a moving object.
Since thermal energy comes from moving molecules and atoms, it is therefore a for of kinetic energy.

2. Which state of matter will take both the volume
and shape of the container that holds it?
A. gas
B. ice
C.liquid
D. Solid
Answer:
The answer would be C) a liquid.
Explanation:
If you were to pour a glass of water into a rectangular container, the water would fill up the container and be in the same shape as the container. That is becuase water flows and it doesn't harden up or take its own shape until it's frozen. The molecules are not tightly secure to each other so they are able to move freely.

In another experiment, the student titrated 50.0mL of 0.100MHC2H3O2 with 0.100MNaOH(aq) . Calculate the pH of the solution at the equivalence point.
pH=8.87
Further explanationReaction
C₂H₄O₂+NaOH⇒CH₃COONa+H₂O
at the equivalence point = mol C₂H₄O₂= mol NaOH
mol C₂H₄O₂ : 50 x 0.1 = 0.5 mlmol=5.10⁻⁴ mol
The two reactants have completely reacted, and there is only salt(CH₃COONa) and water(H₂O), there will be hydrolysis
For acids from weak acids and strong bases (the solution is alkaline) then the calculation:
[tex]\tt [OH^-]=\sqrt{\dfrac{Kw}{Ka}\times M }[/tex]
M=anion concentration=CH₃COO⁻
Ka=acid constant(for CH₃COOH,Ka=1.8.10⁻⁵)
[tex]\tt [OH^-]=\sqrt{\dfrac{10^{-14}}{1.8.10^{-5}}\times 0.1 }[/tex]
[tex]\tt [OH^-]=\sqrt{5.6.10^{-11}}=7.483\times 10^{-6}[/tex]
pOH=6-log 7.483=5.13
pH= 14 - 5.13=8.87
The pH of the solution is the negative log [H] concentration. The pH of the given solution is 8.87 at the equivalence point.
pH:The given Reaction is:
C₂H₄O₂+ NaOH ⇒ CH₃COON + H₂O
The pH of the solution can be calculated by,
[tex]\bold{pH = 14 - pOH}[/tex]................1
So first, calculate for pOH
[tex]\bold {pOH = \sqrt {\dfrac {Kw}{Ka} \times M}}[/tex]
Where,
Ka - dissociatioon constant = 50 x 0.1 = 0.5 ml = 5x10⁻⁴ mol
Kw - concentaion water ionic products = [tex]\bold {10^{-14}}[/tex]
M - anion concentration( CH₃COO⁻) = 0.1 M
Put the values in the formula,
[tex]\bold {pOH = \sqrt {\dfrac {\bold {10^{-14}}}{5\times 10^{-4} mol} \times 0.1}}\\\\\bold {pOH = 7.483 \times 10^{-6}}[/tex]
Since the pOH is the negative log of [OH⁻] concentration,
pOH = 6 -ln 7.483
pOH = 5.13
Put the value of pOH in the first equation,
pH= 14 - 5.13
pH = 8.87
Therefore, the pH of the given solution is 8.87 at the equivalence point.
