Verified Answer
The value of b for carbon dioxide is given as 42.69 x 10-6m3/mol. What...
From van der Waal’s equation (P – an2/V2)(V – nb) = nRT, we know that V = b/NA = 42.69 x 10-6m3/mol/6.023 x 1023 molecules/mol. That equals 7.09 m3/molecule. So the volume of a molecule is 7.09m3.

The chemical equation for fermentation is given below. Scientists study how to induce fermentation in yeast most effectively.C12H22O11 + H2O → 4C2H5OH + 4CO2Experiment 1Since yeast needs sucrose to ferment and molasses is 60% sucrose, scientists first study yeast grown in molasses.Five test tubes are filled with .4 grams of yeast and various molasses concentrations. Carbon dioxide levels are measured as an indication of fermentation for each test tube after one day and again after two days. These levels are shown in Table 1.Experiment 2Five different test tubes are filled with .4 grams of yeast and various pure sucrose dilutions. Carbon dioxide levels are then measured as an indication of fermentation after one and two days. These levels are shown in Table 2.Experiment 3Eight more test tubes were filled with .4 grams of yeast and a 15% sucrose solution. Various combinations of ammonium sulfate, potassium dihydrogen phosphate, minerals, and vitamins were added to the test tubes. Carbon dioxide levels were measured after one and two days. These levels are shown in Table 3.Q.Which of the following is a weakness in the design of Experiment 3?

Both gases and liquids are considered to be fluids that have individual molecules that move around with kinetic and potential energy. Kinetic energy, defined as the energy related to motion, takes three forms: translational energy that occurs as a molecule moves from position A to position B, rotational energy that occurs as a molecule spins around an imaginary axis at its center of mass, and vibrational energy that occurs as individual atoms in a molecular bond move towards and away from each other. Usually, molecules possess varying combinations of kinetic energy forms. In contrast, potential energy is defined as stored energy that could be released to become kinetic energy. The total energy of a molecule is fixed, meaning that a molecule has some combination of kinetic and potential energies.Varying amount of kinetic and potential energies define how molecules in a fluid interact with each other. For example, when the kinetic energy of a molecule is high (greater than 1000J), it can no longer interact with neighboring molecules strongly enough to remain a liquid. However, if the potential energies are too high (greater than 1000 J), molecules cannot escape a liquid to become a gas. If the kinetic energy is high and the potential energy is low, molecules tend to become a gas and can be modeled by an equation known as the Ideal Gas Law:PV=nRT Where P is the pressure of a gas, V is the volume, n is the number of moles of a gas, R is a constant, and T is temperature in degrees Kelvin.The Ideal Gas Law perfectly applies to particles with no mass, no intermolecular interactions, and no true volume. However, real molecules do not adhere perfectly to the Ideal Gas Law.Q. As the kinetic energy of a molecule increases, one would expect the potential energy to
