What is the volumetric flow rate in L/s of a stream of air (density = 1 kg/m3) at 1 kg/s?

Answers

Answer 1
Answer:

Answer:

Volumetric flow rate: Q = 1000 L/s

Explanation:

Volumetric flow rate, also called the rate of fluid flow, is described as volume of fluid that passes a particular point per unit time. The SI unit of volumetric flow rate is m³/s.  

Whereas, mass flow rate is defined as the mass of substance that passes through a point per unit of time. SI unit is kg/s.

Given- mass flow rate: ṁ = 1 kg/s and density: ρ = 1 kg/m³

Therefore, volumetric flow rate can be calculated by

Q = \frac{\dot{m}}{\rho } = (1 kg/s)/(1 kg/m^(3)) = 1 m^(3)/s

Since, 1 m³/s = 1000 L/s

Therefore, volumetric flow rate: Q = 1 m³/s = 1000 L/s

The Michael reaction is a conjugate addition process wherein a nucleophilic enolate anion (the donor) reacts with an α,β-unsaturated carbonyl compound (the acceptor). The best Michael reactions are those that take place when a particularly stable enolate anion is formed via treatment of the donor with a strong base. Alternatively, milder conditions can be used if an enamine is chosen as the donor, this variant is termed the Stork reaction. In the second step, the donor adds to the β-carbon of the acceptor in a conjugate addition, generating a new enolate. The enolate abstracts a proton from solvent or from a new donor molecule to give the conjugate addition product. Draw curved arrows to show the movement of electrons in this step of the mechanism.

What is the relationship between potential and kinetic energy?*As potential energy increases, kinetic energy increases.
O As potential energy increases, kinetic energy decreases.
As potential energy decreases, kinetic energy decreases.
O Potential and kinetic energy are two separate things and have no relationship.

Answers

Answer:

As potential energy increases, kinetic energy decreases

It's an inverse relationship

Final answer:

Potential energy and kinetic energy are related through the law of conservation of energy. When potential energy increases, kinetic energy decreases, and vice versa, as energy is simply converted between these two forms.

Explanation:

The relationship between kinetic energy and potential energy lies within the law of conservation of energy. This law states that energy cannot be created or destroyed, only converted from one form to another.

Potential energy is the energy stored in an object due to its position in a force field or due to its configuration. For example, when you lift a book off the ground, it gains potential energy because of the work done against the force of gravity.

On the other hand, kinetic energy is the energy of an object due to its motion. The same book, when dropped, loses potential energy and gains kinetic energy as it falls towards the ground.

Hence, when potential energy increases, kinetic energy decreases, and vice versa. This is because the total energy (potential + kinetic) must be conserved, assuming no energy is lost to other forms like heat or sound.

Suppose you have been given the task of distilling a mixture of hexane + toluene. Pure hexane has a refractive index of 1.375 and pure toluene has a refractive index of 1.497. You collect a distillate sample which has a refractive index of 1.441. Assuming that the refractive index of the hexane + toluene mixture varies linearly with mole fraction, what is the mole fraction of hexane in your sample?

Answers

Answer:

0.4590

Explanation:

How the refractive index of the hexane + toluene mixture varies linearly with mole fraction, it means that the mole fraction is the fraction that each pure index contribute for the mixture index, so, calling xh the mole fraction of hexane and xt the mole fraction of toluene:

1.375xh + 1.497xt = 1.441

And, xh + xt = 1 (because there are only hexane and toluene in the mixture), so xt = 1- xh

1.375xh + 1.497(1-xh) = 1.441

1.375xh + 1.497 - 1.497xh = 1.441

-0.122xh = -0.056

xh = -0.056/(-0.122)

xh = 0.4590

What is PH?

  • pH, historically denoting "potential of hydrogen" is a scale used to specify the acidity or basicity of an aqueous solution.
  • Acidic solutions are measured to have lower pH values than basic or alkaline solutions

The pH of the solution will be due to excessive acid left and the salt formed. Thus, it will form a buffer solution.

The pH of buffer solution is calculated from Henderson Hassalbalch's equation, which is:

pH= pka+log(salt)/(acid)

pka= -log(ka)

pka =-log(1.8*10^(-5)

The moles of acid are taken as:-

moles = M*V

0.5*50=5

The moles of the base are taken as:-

moles = M*V

0.1*45=4.5


moles of acid left is 0.5

Place all the values to the equation:-

pH=4.74+log(4.5)/(0.5) \n=5.69

Hence, the correct answer is 5.69.

Answer:

pH of soltion will be 5.69

Explanation:

The pH of the solution will be due to excessive acid left and the salt formed. Thus, it will form a buffer solution.

The pH of buffer solution is calculated from Henderson Hassalbalch's equation, which is:

pH=pKa+log(([salt])/([acid]) )

pKa=-log(Ka)

pKa=-log(1.8X10^(-5))=4.74

The moles of acid taken :

moles=molarityXvolume=0.1X50=5mmol

The moles of base taken:

moles=molarityXvolume=0.1X45=4.5mmol

The moles of acid left after reaction :

5-4.5=05mmol

The moles of salt formed = 4.5mmol

Putting values in equation

pH=pKa+log(([salt])/([acid]) )=4.74+log((4.5)/(0.5))=5.69
