Answer:

Lower End

Explanation:

An engine’s lower end, sometimes called the bottom end, contains the engine block, the cylinders, the piston, the connecting rods, and the crankshaft assemblies. The basic function of the lower end components is to convert the up-and-down motion of the pistons into rotary motion that can be used to power a vehicle.

Answer:

You should install a personal firewall, a program that protects your computer from unauthorized access by blocking certain types of communications.

Explanation:

In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted internal network and untrusted external network, such as the Internet.

Given a sorted list of integers, output the middle integer. assume the number of integers is always odd.
Svetllana [295]

integer userInput

integer i

integer mid

integer array(20) number

userInput = 1

for i = 0; userInput >= 0; i = i + 1

  if number[i] > -1

     userInput = Get next input

     number[i] = userInput

i = i - 1

mid = i / 2

if i > 9

  Put "Too many inputs" to output

elseif i % 2 == 0

  Put number[mid - 1] to output

else

  Put number[mid] to output

four quantum numbers that could represent the last electron added (using the Aufbau principle) to the Argon atom. A n = 2, l =0,
marshall27 [118]

Answer:

  • n = 3
  • l  = 1
  • m_l = 1
  • m_s=+1/2

Explanation:

Argon atom has atomic number 18. Then, it has 18 protons and 18 electrons.

To determine the quantum numbers you must do the electron configuration.

Aufbau's principle is a mnemonic rule to remember the rank of the orbitals in increasing order of energy.

The rank of energy is:

1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p < 5s < 4d < 5p < 6s < 4f < 5d < 6p < 7s < 5f < 6d < 7d

You must fill the orbitals in order until you have 18 electrons:

  • 1s² 2s² 2p⁶ 3s² 3p⁶   : 2 + 2 + 6 + 2 + 6 = 18 electrons.

The last electron is in the 3p orbital.

The quantum numbers associated with the 3p orbitals are:

  • n = 3

  • l = 1 (orbitals s correspond to l = 0, orbitals p correspond to l  = 1, orbitals d, correspond to l  = 2 , and orbitals f correspond to  l = 3)

  • m_l can be -1, 0, or 1 (from - l  to + l )

  • the fourth quantum number, the spin can be +1/2 or -1/2

Thus, the six possibilities for the last six electrons are:

  • (3, 1, -1 +1/2)
  • (3, 1, -1, -1/2)
  • (3, 1, 0, +1/2)
  • (3, 1, 0, -1/2)
  • (3, 1, 1, +1/2)
  • (3, 1, 1, -1/2)

Hence, the correct choice is:

  • n = 3
  • l  = 1
  • m_l = 1
  • m_s=+1/2
