The most common element found in crayons would be carbon and hydrogen. Since crayons are made up of paraffin and other chemical pigments. Paraffin is wax like material, which is derived from petroleum, wood, or coal. All three contain large amounts of hydrocarbons, which is carbon and hydrogen compounds.
Hello!
Antifreeze says it in the name. This means that it helps prevent freezing. The liquid that would freeze if you wouldnt use the antifreeze is water. This means that the antifreeze has to have a higher freezing point then water, because otherwise it would only freeze faster!
Hope this helped you!
Here is the chemical equation for gun powder, in it’s simple form:
<span>2 KNO3 + S + 3 C → K2S + N2 + 3 CO2.</span>
This is the same simplified formula, only balanced:
<span>10 KNO3 + 3 S + 8 C → 2 K2CO3 + 3 K2SO4 + 6 CO2 + 5 N2.</span>
- <span>The </span>speed of light<span> is the </span>speed<span> electromagnetic waves travel. The </span>speed of light<span> is 3.0 x 108 m/s in space. The </span>speed of light<span> is the same in all matter. The </span>speed<span> of higher frequency </span>light <span>slows down more than lower frequency </span>light<span> in matter.</span>
