Answer:
C) Liquids and gases
Explanation:
<em>The correct answer would be liquids and gases.</em>
<u>The molecules of liquids and gases move randomly when held in a container. The random movement causes a collision between the molecules of the liquids/gases and between the walls of the container, creating pressure in the process. </u>This is unlike the molecules of solids that vibrate about fixed positions.
Hence, the correct option is C.
3Mg + N₂ → Mg₃N₂
n(Mg) = 12,2g÷24,4g/mol = 0,5mol - limiting reagente.
n(N₂) = 5,16g÷28g/mol = 0,18mol
n(Mg₃N₂):n(Mg) = 1:3, n(Mg₃N₂) = 0,166mol
m(Mg₃N₂) = 0,166mol·101,2g/mol = 16,8g.
%(N)= 2·Ar(N)÷Mr(Mg₃N₂) = 2·14÷101,2 = 27,66% = 0,2766
%(Mg) = 3·Ar(Mg)÷Mr(Mg₃N₂) = 3·24,4÷101,2 = 72,34%
or 100% - 27,66% = 72,34%.
hello, the answer to your question would be TRUE!
(this is because a phylum is "a principal taxonomic category that ranks above class and below kingdom.")

The answer is going to be C. Although producing at a fast rate, fossil fuel cannot be re-used or recycled. Wind can be re-used, geothermal energy can be re-used, and hydro energy can be re-used.
Hope this Helps! :)
Answer:
11625 miles
Explanation:
A second of light is the distance that light travels in a second. It has a value of 299792458 kilometers or if we do the unit conversion, 186,000 miles. A mile is 1.609 kilometers
Let's make a rule of three:
1 light s travels a distance of 186000 miles
0.062500 light s would travel a distance of (0.062500 . 186000) = 11625 miles
