Explanation:

Whenever you have an binary compound such as this, you can look at the individual elements for the name. The first word will simply be the prefix + the name of the element.

*** Notice you don't need to put a prefix if theres only 1. This is understood as mono. Only on the first word.

For the second word, its simply the root + ide.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

the answer is minerals.
