Answer:
A. False
B. False
C. True
Explanation:
<em>A. The three quantum numbers (n, l, and ml) define an atomic orbital. If n, the principal quantum number, has a value of 6 the maximum value of l is 6.</em> FALSE. The first part is true. However, the maximum value of l is n-1. So, if n is 6, l can take values up to 5.
<em>B. The principal quantum number, n, can have any integer value from 0 to infinity. For electrons in s, p, and d orbitals, the d electrons are the most shielded.</em> FALSE. n can take positive integer values, that is, it cannot take the value 0. Usually, the d electrons are the most shielded.
<em>C. The magnetic quantum number, ml indicates the orientation of the orbital in the space around the nucleus.</em> TRUE. For instance, spheric s orbital has only 1 orientation (1 value for ml), whereas lobed p orbital can be oriented along the three axes (3 values for ml).
Salt dissolving into water is a physical change because it can be reversed as in chemical change cannot be reversed as in you can boil water and have the salt on the bottom
The definition in Volume is a the amount of space a substance or object occupies, or that is enclosed within a container, especially when great. For example "The sewer could not cope with the volume of rainwater" . You can say it in different ways, such as capacity, size, magnitude, mass, bulk, extent and more. I hope this helps :-).
