Decide which of the following statements are true and which are false.
Decide which of the following statements are true and which are false. At constant temperature, the lighter the gas molecules, the larger the average kinetic energy. Real gas molecules behave most ideally at low temperature and high pressure. As temperature decreases, the average kinetic energy of a sample of gas molecules increases In order for two separate 1.0 L samples of O2(g) and H2(g) to have the same average velocity, the H2(g) sample must be at a higher temperature than the O2(g) sample At constant...

Which of the following statements is FALSE?
Group of answer choices A large stock is typically more volatile
than a portfolio of large stocks. Investors would not choose to
hold a portfolio that is more volatile unless they expected to earn
a higher return. Smaller stocks have lower volatility than larger
stocks.

Decide which of the following statements are true and which are false. True Real gas molecules have a volume and exert attractive forces on one another. False As temperature increases, the average kinetic energy of a sample of gas molecules decreases. False In order for two separate 1.0 L samples of O2(g) and H2(g) to have the same average velocity, the O2(g) sample must be at a higher temperature than the H2(g) sample.

Which of the following statements is FALSE ? Atoms undergo electronic transitions but not rotational or vibrational transitions B Typically, IR radiation causes vibrational transitions of molecules O c Compared to IR, UV radiations have longer wavelengths and less energy D Shorter the wavelength of a radiation higher the frequency
Which of the following statements about activation energy is correct? Reactions may have negative activation energies....
Which of the following statements about activation energy is correct? Reactions may have negative activation energies. It is the minimum energy required for colliding reacting particles to react. It is the maximum energy a reacting molecule may possess. In general, reactions with higher activation energies are faster. Question 35 2 pts Characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true false status of the statements using the choices. (1) Oxidation and...

Which of the following statements concerning lattice energy is false? It is often defined as the energy released when an ionic compound forms from its ions. MgO has a higher lattice energy than NaF. In the Lewis structure for elemental nitrogen, there is (are) a single bond between the nitrogen atoms a double bond between the nitrogen atoms a triple bond between the nitrogen atoms three unpaired electrons two unpaired electrons, one on each nitrogen What is the geometry of...

3. Which of the following statements best explains why nitrogen gas at STP is less dense than Xe Has at STP? a) Because Xe is a noble gas, there is less tendency for the Xe atoms to repel one another, so they pack more densely in the gas state. b) Xe atoms have a higher mass than N2 molecules, Because both gases at STP have the same number of molecules per unit volume, the Xe gas must be denser, c)...

B) The temperature a The temperature and pressure determine the physical state in which a sample of matter will exist C) The solid state of matter is more organized than the liquid state of matter. D) Gases will assume the volume and shape of their containers. 41) How many moles of gas are present in...

q1 Which of the following statements is false about health savings accounts (HSAs)? a. Distributions from HSAs which are used for qualifying medical expenses are not subject to tax or penalty. b. Deductible contributions to HSAs are unlimited. c. Taxpayers qualifying for Medicare do not qualify to make HSA contributions. d. Distributions from HSAs which are not used for medical expenses are generally subject to a 20 percent penalty and income taxes. e. HSAs must be paired with qualifying high-deductible...
