The SI V-Scope is indeed a virtual microscope program that can stimulate the use of a compound light microscope so this is <u>TRUE</u>.
<h3>What is a SI V-Scope?</h3>
The SI V-Scope stands for a Science Interactive and then Virtual scope which is used simulate the way that a compound light microscope works.
These microscopes are very useful because they help people who don't have a physical microscope to access microscopes wherever they are.

Considering the definition of percentage by mass, the sample of pure lithium nitrate contains 7.99% lithium by mass.
<h3>Definition of percentage by mass</h3>
The percentage by mass expresses the concentration and indicates the amount of mass of solute present in 100 grams of solution.
In other words, the percentage by mass of a component of the solution is defined as the ratio of the mass of the solute to the mass of the solution, expressed as a percentage.
The percentage by mass is calculated as the mass of the solute divided by the mass of the solution, the result of which is multiplied by 100 to give a percentage. This is:

<h3>This case</h3>
Because percent by mass indicates the ratio of solute to solution based on mass, if the sample has twice the mass of the first sample, the ratio remains constant.
So the percentage by mass is the same.
That is, the sample of pure lithium nitrate contains 7.99% lithium by mass.

Explanation:
answer my latest question I beg you
Answer:
4pi/3
Explanation:
XY = YZ = XZ = 2
angle YXZ is pi/3
wxy is 2pi/3
Area of the circle = pi*r^2 = 4pi
Area of the shaded area = 4pi * (2pi/3)/(2pi) = 4pi/3
