What is the mass measurement shown on the scales of this balance

a)73.925
b) 70.932
c) 73.92
d) 70.923

The correct answer is option C) 73.92

Explanation:

Hi!

Let's solve this!

On the scale we see:

In the first rule the number 70, in the second rule the 3 so we have 73.

In the third rule we see the 9 marked and run two places.

According my vision of the image, we conclude that the correct answer is option C) 73.92

A) 73.925

Explanation:

70+3=73, and when you look at the third ruler, the arrow is pointing after the 2nd mark after .9. Since the arrow is NOT directly on the 2nd mark, the answer is 73.923 instead of 73.92. But from your answer choices, it would be 73.925.

i believe that it is a exoplanet

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
