Redox Reaction is an ionic bond
Percent composition of a molecule is found through the molecular formula (Mass of each element found in a single mole of the molecule ÷ total molar mass of the molecule). This tells you how much of a specific element makes up the molecule.
Also be aware that 2 molecules can have the same % composition but different formulas.
Answer:
8800 cm / s
Explanation:
There are 100 cm / m
so: 88 m/s * 100 cm / m = 8800 cm/s
( see how the 'm' cancels out and you are left with cm /s ?)
Answer:
<em>Most fire extinguishers work by separating the fuel from the oxygen. The oxygen comes from the air. It is the same oxygen we breathe. Since the oxygen has to be in contact with the fuel, if you can coat the fuel with something that keeps the oxygen away, the fire will go </em><em>out.</em><em> </em><em>S</em><em>ome </em><em>ways </em><em>of </em><em>using </em><em>fire </em><em>extinguisher </em><em>are:</em>
- <em> Water extinguishers work mainly by cooling (removing heat), but a dense spray of water droplets also helps to cut off oxygen. </em>
- <em> Dry powder extinguishers soak up heat, melt on the fuel, and cut off oxygen, but they also neutralize the </em><em>fuel</em><em> (cutting it off from the </em><em>fire)</em><em> </em><em>.</em>
