Answer:
Carbon is a chemical element, like hydrogen, oxygen, lead or any of the others in the periodic table. Carbon is a very abundant element. It exists in pure or nearly pure forms – such as diamonds and graphite – but can also combine with other elements to form molecules.
The student needs to dilute the stock to get the proper concentration. And during the dilution, the molar number of solute will not change. So the volume of stock needed is 2*0.1/1.75=0.114 L. Then dilute to 2.00 L.
It is<u> true</u> that the moment of inertia of a hoop that has a mass and a radius is greater than the moment of inertia of a disk that has the same mass and radius.
Lower moments of inertia signify that only small forces are required to create a rotation, whereas higher moments of inertia mean that greater force must be used. The masses with the largest moment of inertia are those that reside furthest from the axis of rotation.
Due to the fact that a ring's center of mass is located on an axis that is perpendicular to its plane and passes through it, a ring has a higher moment of inertia than that of a circular disc of equal mass and radius. Because all of a ring's mass has been concentrated at the rim, which is furthest from the axis, which has a greater moment of inertia.
Therefore, the given statement is true.

It is the same because it's ratio is still the same between all three, and it is the same material.
Answer:
0.369M
Explanation:
☆ Volume has to be in litres
Molarity of solution
= 0.99 ÷2.5
= 0.369 M
