If 1.00 mol of argon is placed in a 0.500-L container at 22.0 ∘C , what is the difference between the ideal pressure (as predict

ed by the ideal gas law) and the real pressure (as predicted by the van der Waals equation)? For argon, a=1.345(L2⋅atm)/mol2 and b=0.03219L/mo

Answer:

The answer to your question is ΔP = 1.57 atm

Explanation:

Data

moles = 1

volume = 0.5 L

Temperature = 22°C  or 295°K

Pressure = ?

a) Ideal Gas

                      PV = nRT          R = 0.082 atm L / mol°K

-Solve for P

                     P = nRT/V

                     P = (1)(0.082)(295)/ 0.5

                     P = 23.944/ 0.5

                    P = 47.9 atm

b) Van der Waals

                     (P + a/v²)(v - b) = RT

- Substitution

                     (P + 1.345/0.5²)(0.5 - 0.03219) = (0.082)(295)

- Simplification

                     (P + 5.38)(0.46781) = 24.19

                     P + 5.38 = 24.19/0.46781

                     P + 5.38 = 51.71

-Solve for P

                      P = 51.71 - 5.38

                      P = 46.33 atm

c) The difference between both Pressures is

        ΔP = 47.9 - 46.33

             = 1.57 atm

physics During exercise, a person may give off 753,480 J of heat in 30 minutes by evaporation of water from the skin. How much w
Tju [1.3M]

Answer : The amount of water lost was, 333.4 grams.

Explanation : Given,

Heat released = 753480 J

Formula used :

Q=mL

where,

Q = heat released  = 753480 J

m = mass  = ?

L = latent heat vaporization of water = 2260J/g

Now put all the given values in the above formula, we get:

753480J=m\times (2260J/g)

m=333.4g

Thus, the amount of water lost was, 333.4 grams.

A sample of gas occurs 9.0mL at a pressure of 500mmHg. A new volume of the same sample is at 750mmHg. Use two significant figure
Rufina [12.5K]

Answer:

\large \boxed{\text{6.0 mL} }

Explanation:

The temperature and amount of gas are constant, so we can use Boyle’s Law.

p_{1}V_{1} = p_{2}V_{2}

Data:

\begin{array}{rcrrcl}p_{1}& =& \text{500 mmHg}\qquad & V_{1} &= & \text{9.0 mL} \\p_{2}& =& \text{750 mmHg}\qquad & V_{2} &= & ?\\\end{array}

Calculations:  

\begin{array}{rcl}500 \times 9.0 & =& 750V_{2}\\4500 & = & 750V_{2}\\V_{2} & = &\dfrac{4500}{750}\\\\& = & \textbf{6.0 mL}\\\end{array}\\\text{The volume of the gas is } \large \boxed{\textbf{6.0 mL}}

Viefleur [7K]

<u>Answer:</u> The chemical formula of the given compound will be S_2O_2

<u>Explanation:</u>

The compound formed is disulfur dioxide.

Covalent compound is defined as the compound which is formed by the sharing of electrons between the atoms forming a compound. These are usually formed when two non-metals react.

Disulfur dioxide is a covalent compound because sharing of electrons takes place between sulfur and oxygen. Both the elements are non-metals and hence, will form covalent bond.

The nomenclature of covalent compound is given by:

  • The less electronegative element is written first.
  • The more electronegative element is written then, and a suffix is added with it. The suffix added is '-ide'.
  • If atoms of an element is greater than 1, then prefixes are added which are 'mono' for 1 atom, 'di' for 2 atoms, 'tri' for 3 atoms and so on..

Hence, the chemical formula of the given compound will be S_2O_2

How many grams of glucose, C6H12O6, in 2.47 mole?
statuscvo [17]
First, we need to find the atomic mass of C_{6}H_{12}O_{6}.

According to the periodic table:
The atomic mass of Carbon = C = 12.01
The atomic mass of Hydrogen = H = 1.008
The atomic mass of Oxygen = O = 16

As there are 6 Carbons, 12 Hydrogens and 6 Oxygens, therefore:
The molar mass of  C_{6}H_{12}O_{6} = 6 * 12.01 + 12 * 1.008 + 6 * 16

The molar mass of  C_{6}H_{12}O_{6} = 180.156 grams/mole

Now that we have the molar mass of  C_{6}H_{12}O_{6}, we can find the grams of glucose by using:

mass(of glucose in grams) = moles(of glucose given in moles) * molar mass(in grams/mole)

Therefore,
mass(of glucose in grams) = 2.47 * 180.156
mass(of glucose in grams = 444.99 grams

Ans: Mass of glucose in grams in 2.47 moles = 444.99 grams
