Answer: 6 unpaired electrons

Explanation:

Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom.

Molybdenum is an element with atomic number of 42 and thus 42 electrons. The electrons are filled according to Afbau's rule in order of increasing energies and thus the electronic configuration in terms of noble gas is:

[Kr]4d^55s^1

The 5 electrons in d orbital and 1 electron in s orbital are unpaired. Thus there are 6 unpaired electrons

Francine makes several measurements of the mass of a metal block. The data set is shown in the table below.
BARSIC [14]

Answer:

Mean

Explanation:

The mean of a series of measurements is calculated when a<em>ll the measurements are added up and then divided by the number of measurements taken</em>, as follows:

  • Sum of Measurements = 20.73 + 20.76 + 20.68 + 20.75 = 82.92

As<u> there are 4 measurements</u>, the mean is:

  • Mean = 82.92 / 4 = 20.73

What happens when you grow the same crop over and over again in the same field
irinina [24]
Well there's a couple reasons why. First, the land itself can become “tired" and less fertile<span>. This is because the same type of </span>crop<span> planted repeatedly in the same area keeps draining the land of the same nutrients needed for that plant's growth. Pest can also plant their nest near the crop if the farmer continues to plant the same crop in the same place. 

Which is the reason why things such as "crop rotation" exist to keep things fresh, and prevent what I described above from happening.</span>

Which of these energy resources are renewable? Select all that apply.
xz_007 [3.2K]

The correct options are option B and D, that is, wind power and geothermal energy.  

The form of energy which is gathered from renewable resources is known as renewable energy. This form of energy gets restocked on a human timescale like wind, sunlight, tides, waves, rain, and geothermal heat.  

Renewable energy usually provides energy in four essential fields, that is, air and water heating/cooling, electricity generation, rural energy services, and transportation.
