Yes MgF2 is a pure substance
If you mean m (subscript l) is (-2,-1,0,1,2)
its a 3d orbital so it can hold 2 electrons, however, like in an electron diagram a 3d orbital has 5 boxes can can hold 2 electrons that is how i got 10 total but if you mean just in box 2 then only 2 can share it.
Does that make sense?
A blue whale will have the largest Schwarzschild radius, as it has larger mass than the other. Thus option A is correct.
<h3>
What is Schwarzschild radius?</h3>
Schwarzschild radius is defined as the radius below which the gravitational pull between a body's particles causes it to collapse gravitationally.
It can also be defined as the radius of a collapsing astronomical object at which gravitational forces necessitate an escape velocity greater than the speed of light, resulting in a black hole.
The Schwarzschild radius is solely determined by the object's mass, hence the larger the mass, the larger the Schwarzschild radius.
Thus. a blue whale will have the largest Schwarzschild radius, as it has larger mass than the other. Thus option A is correct.

Answer:
Explanation:
Matter is anything that has weight and occupies space.
To prove that a bicycle is a matter, we need to show that it has weight and will occupy space.
When you put the bicycle on a weighing scale, you will see the weight of the bicycle. This a proof that bicycle is a matter.
To show that the bicycle can occupy space, place the device in a tank full of water. From the tank, the bicycle will displace some water. Substances that cannot occupy space will not behave in such manner.
