The normal boiling point of fingernail polish remover is 56℃  the vapor pressure of fingernail polish remover at the salon 0.027 atmospheric pressure

<h3>What is atmospheric pressure?</h3>

The pressure exerted by the vapors due to the atmosphere as it is surrounded by it only is known as vapor pressure and its unit is atm.

As air have small molecules which forms multiple layers and create pressure.

vapor pressure = {1/T1 - 1/T2}

T1 = 56 c

T2 = 22 c

substituting the values,

vapor pressure = [ 1/ 56 - 1 / 22 ]

                         = 0.027 atm.

Therefore, the vapor pressure of nail paint remover is 0.027 atm

Give the number of protons and electrons in each of these ions or atoms (show your work) Cs. Ba , .s
Morgarella [4.7K]

Explanation:

The sum of total number of protons present in an element is known as atomic number of the element.

  • As atomic number of Cs is 55.

And, it is known that for a neutral atom the number of protons equal to the number of electrons.

Since, no charge in present on given Cs atom it means that it is neutral in nature. Hence, number of protons and electrons present in Cs are 55.

  • For Ba, it is also neutral in nature and atomic number of barium is 56. Hence, number of protons and electrons present in Ba are 56.
  • For S, there is no charge on it so it is also neutral in nature. Atomic number of S is 16. Hence, number of protons and electrons present in S are 16.

TRUE/FALSE. the profit-maximizing rule leaves room for cases where it is both possible and reasonable for a firm to operate at a
SCORPION-xisa [38]

The statement was false as it mentioned, the profit-maximizing rule leaves room for cases where it is both possible and reasonable for a firm to operate at a loss over the long run

What is profit-maximizing rule ?

According to the Profit Maximization Rule, if a corporation want to maximise its profits, it must select the level of output where Marginal Cost (MC) equals Marginal Revenue (MR) and the Marginal Cost curve is increasing. To put it another way, it must generate at a level where MC = MR.

The profit maximization rule formula is as follows:

MC = MR

The marginal cost is the cost increase caused by manufacturing one extra unit of an item.

The difference in total revenue as a result of altering the rate of sales by one unit is referred to as marginal revenue. The slope of Total Revenue is also known as Marginal Revenue.

Total Revenue - Total Costs = Profit

Profit maximisation happens when there is a considerable gap or disparity between total revenue and total cost.

so the given statement the profit-maximizing rule leaves room for cases where it is both possible and reasonable for a firm to operate at a loss over the long run. was a false statement.

The double replacement reaction between calcium nitrate (Ca(NO​3​)​2)​ and potassium oxide (K​2O​ ) is shown below:
Llana [10]

Answer:

Mass = 2.355 g

Explanation:

Given data:

Mass of K₂O needed = ?

Mass of KNO₃ produced = 5.00 g

Solution:

Chemical equation:

K₂O + Ca(NO₃)₂     →   CaO +  2KNO₃

Number of moles of KNO₃:

Number of moles = mass/molar mass

Number of moles = 5.00 g/ 101.1 g/mol

Number of moles = 0.05 mol

now we will compare the moles of KNO₃ and K₂O.

               KNO₃           :             K₂O

                  2                :               1

                 0.05           :           1/2×0.05 = 0.025 mol

Mass of potassium oxide needed in gram:

Mass =  number of moles × molar mass

Mass = 0.025 mol × 94.2 g/mol

Mass = 2.355 g
