Answer:
t = 1862 s
Explanation:
To do this, we need first to determine the theorical detention time, which can be determined with the following expression:
t₀ = ∀/Q (1)
Where:
t₀: detention time
∀: Volume of the fluid in the reactor
Q: Flow rate in the reactor
With this time, we must use the following expression to determine the time that the workers will take to vent the tank:
C = C₀ e^(-t/t₀) (2)
From here, we must solve for time t, and the expression will be:
t = ln(C₀/C) * t₀ (3)
Now that we know the expression to use, let's solve for t. Using (1) to determine the detention time, ∀ is 1900 m³, and Q is 2.35 m³/s so:
t₀ = 1900 / 2.35 = 808.51 s
Now, let's solve for the time t. C will be 0.0015 mg/L (or 1.5 mg/m³ cause in 1 m³ we have 1000 L) and C₀ 15 mg/m³:
t = ln(15/1.5) * 808.51
t = 1861.66 s or simply 1862 sHope this helps
Draw the organic product(s) of the reaction of acetophenone with H2NNH2, KOH.
If no reaction occurs, tell OWL by drawing ethane (CH3CH3).
Do not separate two structures with a + sign.
Answer:
From Wolff Kishner Reduction we can say that the product thus formed will be ethylbenzene.
Explanation:We know that acetophenone has (COCH3) attach to it as a functional group. When it reacts with hydrazine that is (NH2NH2) in the presence of a strong base such as KOH and heat, an intermediate known as hydrazone is formed. Hydrazone are a cousin of imines. Here the oxygen gets replaced with hydrazine and water is released. Then after deprotonation of NH we have protonation at carbon of the functional group. Then we again have deprotonation of NH and finally N2 is released and we have a protonation of carbon which results in ethylbenzene.

Calculate the volume in milliliters of a 0.595M iron(II) bromide solution that contains 100. g of iron(II) bromide . Round your answer to significant digits.
The volume, in milliliters of 0.595 M iron (II) bromide that will contain 100 g of the substance will be 779.3 mL.
Molarity problemThe molarity of a solution is the ratio of the mole of solutes to the volume of the solution. Mathematically:
Molarity = mole/volume
Also, mole = mass/molar mass
Thus, 100 g of iron (II) bromide (molar mass = 215.65 g/mol) would be:
100/215.65 = 0.4637 mol
Making the volume of the subject from the equation above:
Volume = mole/molarity
= 0.4637/0.595
= 0.7793 liters
In milliliters, 0.7793 liters = 0.7793 x 1000 = 779.3 mL
Thus, the volume of the solution would be 779.3 mL.

The molality of a solution is defined as the number of moles of a solute per kilogram of solvent. It depends on the mass of the solvent. It is denoted by m. It is also called Molal Concentration.
What is Molality?Molarity (M), which is determined by dividing the solute's mass in moles by the volume of the solution in litres, is the most widely used unit to express solution concentration: litres of solution/moles of solute equals M.
The following equation can be used to determine the molality: m = (Number of moles of the solute)/ (Mass of the solution in litres.) Molality is measured in kg/mol. The terms molality and molal concentration are interchangeable. The equation for calculating molality,
m = (Moles of the Solute, in Number)/ (Mass of the solution in litres.)

You have 100 mL of a 6 M solution of NaCI and you need to dilute it to 400 mL. What is the molarity of the new solution?
Answer: 1.5 M
Explanation:
In order to find the molarity of the new solution, we need to use the formula M1V1 = M2V2, where M1 is the initial molarity, V1 is the initial volume, M2 is the final molarity, and V2 is the final volume.
Given that the initial volume is 100 mL and the initial molarity is 6 M, we can plug in the values and solve for M2:
6 M x 100 mL = M2 x 400 mL
M2 = (6 M x 100 mL) / 400 mL
M2 = 1.5 M
So the new solution will have a molarity of 1.5 M.

Determine the average rate of change of B from t=0 to t=362 s.
A yields 2B
time(s): 0, 181, 362
Concentration of A (M): 0.170, 0.425, 0.140
Answer must be in M/s
The average rate of change of B from t=0 to t=362 s is [tex]0.001883 M/s.[/tex]
How to find the average rate of change?The average rate of change of B can be determined using the formula:
rate = (change in concentration of B) / (change in time)
We can calculate the change in concentration of B by subtracting the initial concentration of B from the final concentration of B:
change in concentration of B = final concentration of B - initial concentration of B
We can calculate the change in time by subtracting the initial time from the final time:
change in time = final time - initial time
We can use the stoichiometry of the reaction to convert the concentration of A to the concentration of B:
2A -> B
change in concentration of B = (2 * change in concentration of A)
We can use this information to calculate the average rate of change of B from t=0 to t=362 s:
change in concentration of B = [tex](2 * (0.425 M - 0.170 M)) = 0.680 M[/tex]
