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.

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.

The correct order given below shows the changes that occurs in a mice population in response to changes in their environment:

  • The population of mice is in an environment with many black rocks
  • Mice with black for are more likely to survive and reproduce than mice with brown fur
  • After many generations, most of the mice in the population have black fur
  • A sandstorm covers most of the population's environment with brown sand
  • Mice with black fur are less likely to survive and reproduce than mice with brown fur
  • After many generations, most of the mice in the population have brown fur

<h3>What is the correct order for natural selection in the desert environment given?</h3>

Based on the process of natural selection due to envrionmental pressures, the population of the mice in the desert changes as follows before and after the environmental change:

  • The population of mice is in an environment with many black rocks
  • Mice with black for are more likely to survive and reproduce than mice with brown fur
  • After many generations, most of the mice in the population have black fur
  • A sandstorm covers most of the population's environment with brown sand
  • Mice with black fur are less likely to survive and reproduce than mice with brown fur
  • After many generations, most of the mice in the population have brown fur

Therefore, the correct order shows the changes that occurs in a mice population in response to changes in their environment.

The​ half-life of a certain tranquilizer in the bloodstream is 5050 hours. how long will it take for the drug to decay to 8686​%
Novosadov [1.4K]
Using the exponential decay model; we calculate "k"
We know that "A" is half of A0
A = A0 e^(k× 5050)
A/A0 = e^(5050k)
0.5 = e^(5055k)
In (0.5) = 5055k 
-0.69315 = 5055k
 k = -0.0001371
To calculate how long it will take to decay to 86% of the original mass
0.86 = e^(-0.0001371t)
In (0.86) = -0.0001371t
-0.150823 = -0.0001371 t
 t = 1100 hours

Draw the product formed when the compound shown below undergoes a reaction with hcl in ch2cl2.
Taya2010 [7]
 The product formed  when HCl and CH2Cl2 react  is   CH4
         H
     H-C- H    methane structure 
         H

  HCl    react with CH2Cl2  to form  methane (CH4) and chlorine gas(Cl2)
that is,

2HCl(g)  + CH2Cl2(l)  = CH4 (g) +2Cl2 (g)
