Answer:

7.5 L

Explanation:

At constant temperature and number of moles, Using Boyle's law  

{P_1}\times {V_1}={P_2}\times {V_2}

Given ,  

V₁ = 3.00 L  

V₂ = ?

P₁ = 36.74 psi = 2.5 atm (Conversion factor, 1 psi = 0.068046 atm)

P₂ = 1 atm  (Atmospheric pressure as it comes to surface)

Using above equation as:

{P_1}\times {V_1}={P_2}\times {V_2}

{2.5\ atm}\times {3.00\ L}={1\ atm}\times {V_2}

{V_2}=\frac{{2.5}\times {3.00}}{1}\ L

{V_2}=7.5\ L

Nuclear power plants produce energy using fission. One common fuel, uranium-235, produces energy through the fission reaction 23
Vikentia [17]

Answer:

mass of U-235  = 15.9 g (3 sig. figures)

Explanation:

1 atom can produce -------------------------> 3.20 x 10^-11 J energy

x atoms can produce ----------------------> 1.30 x 10^12 J energy

x = 1.30 x 10^12 / 3.20 x 10^-11

x = 4.06 x 10^22 atoms

1 mol ----------------------> 6.023 x 10^23 atoms

y mol ----------------------> 4.06 x 10^22 atoms

y = 0.0675 moles

mass of U-235 = 0.0675 x 235 = 15.8625

mass of U-235  = 15.9 g (3 sig. figures)

At a given temperature, you have a mixture of benzene (vapor pressure of pure benzene = 745 torr) and toluene (vapor pressure of
swat32
Ideal solutions obey Raoult's law, which states that:

P_i = x_i*(P_pure)_i

where
P_i is the partial pressure of component i above a solution
x_i is the mole fraction of component i in the solution
(P_pure)_i is the vapor pressure of pure component i

In this case,

P_benzene = 0.59 * 745 torr = 439.6 torr
P_toluene = (1-0.59) * 290 torr = 118.9 torr

The total vapor pressure above the solution is the sum of the vapor pressures of the individual components:

P_total = (439.6 + 118.9) torr = 558.5 torr

Assuming the gas phase also behaves ideally, the partial pressure of each gas in the vapor phase is proportional to its molar concentration, so the mole fraction of toluene in the vapor phase is:

118.9 torr/558.5 torr = 0.213

2. If a machine produces 225 parts in an 8 hour day, how many minutes will it take to
vekshin1

21.28s

Explanation:

This is a rate problem.

Number of parts produced = 225

 Time taken to produce= 8hours

Rate of production is the amount of parts produced in a duration of time.

  Now convert  8 hours to minute;

   60 minutes = 1hr

    8 hours  = 60 x 8 = 480minutes

Now:

Rate of production = \frac{225 parts}{480min} = 0.47parts/minute

  Now, to produce 10 parts;

   It takes;

                 0.47 parts to be produced in 1 minute

                 10 parts would be produced in \frac{10}{047} = 21.28s

Which of the reagents listed below would efficiently accomplish the transformation of 2-methyl-3-cyclopentenol into 2-methyl-3-c
Anni [7]

The answer to this question would be CrO3 or H2SO4. These reagents would efficiently accomplish the transformation of 2-methyl-3-cyclopentenol into 2-methyl-3-cyclopentenone. The synthetic strategy is used for the bond forming and transformation of the molecule. The reagent required depends on the type of molecule.

Americium-242 has a half-life of 6 hours. If you started with 24 g and you now have 3 g, how much time
kogti [31]
How many times has it halved?

24/2 = 12
12/2 = 6
6/2 = 3

It halved three times.
It halves once every 6 hours.

18 hours have passed.
