How do the energy and the most probable location of an electron in the third shell of an atom compare to the energy and the most probable location of an electron in the first shell of the same atom?(1) In the third shell, an electron has more energy and is closer to the nucleus.
(2) In the third shell, an electron has more energy and is farther from the nucleus.
(3) In the third shell, an electron has less energy and is closer to the nucleus.
(4) In the third shell, an electron has less energy and is farther from the nucleus.

Answer 1

Answer: The answer is (2). You can think about this question in terms of the Bohr's model of the atom or in terms of quantum chemistry. In the Bohr model, electrons exist in discrete "shells," each respresenting a fixed spherical distance from the nucleus in which electrons of certain energy levels orbit the nucleus. The larger the shell (the greater the "orbit" radius), the greater the energy of the "orbiting" electron (I use quotations because electrons don't actually orbit the nucleus in the traditional sense, as you may know). Thus, according to the Bohr model, a third shell electron should be farther from the nucleus and have greater energy than an electron in the first shell.The quantum model is differs drastically from the Bohr model in many ways, but the essence is the same. A larger principal quantum number indicates 1) greater overall energy and 2) a probability distribution spread a bit more outward.

A 10.0 mL syringe contains 0.10 g of nitrogen gas at 0.0 degrees Celsius. What is the pressure inside the syringe?

Answers

Since the sample inside the syringe is a gas, we assume that it is an ideal gas that is we use the expression PV = nRT. We can easily calculate the pressure as follows:

n = m /MM = 0.10 / 28 = 0.0036 mol

P = nRT / V = 0.0036(0.08206)(273.15) / 0.010
P = 8 atm

Answer:

The correct answer is 8.0 atm.

A. The reaction will stop.
B. The reaction will slow down.
C. The reaction will speed up.

Answers

C. the reaction will speed up, as the role of a catalyst is to increase the rate of reaction
