signifies standard temperature and pressure. This conditions are at 1
atmospheric pressure and 0 degrees Celsius. It has been said that at these
conditions, one mole of a gas molecule is equivalent to 22.4 liters of volume.
Therefore, the correct answer is option B. </span>
<u>3.04 </u> liters of propane(C₃H₈) are needed to react with 15.2 liters of oxygen to produce water and carbon dioxide
Explanation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
The mole ratio between the propane and oxygen in the equation is 1 : 5 as can be seen in the equation.
If the amount of O₂ reacting is 15.2 L then the amount of propane required is;
1 : 5
X : 15.2
We cross multiply the ration
5x = 15.2 * 1
X = 15.2/5
X = 3.04
= 3.04 L
Sugar is considered an organic compound,
Because it is made up a long chain of carbon atoms.
The fire triangle is composed of
1) heat
2) fuel
3) oxidizing agent (oxygen)
Types of fire extinguishers:
1) Water and Foam - <span> extinguish the fire by taking away the </span>heat<span> element of the fire triangle. Foam agents separate the </span>oxygen<span> element from the other elements.</span>
2) Carbon dioxide - <span>extinguish fire by taking away the </span>oxygen<span> element of the fire triangle and also be removing the </span>heat<span> with a very cold discharge.</span>
3) Dry Chemical - <span>extinguish the fire primarily by interrupting the </span>chemical reaction<span> of the fire triangle.</span>
4) Wet Chemical - <span>extinguishes the fire by removing the heat of the fire triangle and prevents re-ignition by creating a barrier between the </span>oxygen<span> and </span>fuel<span> elements</span>
5) Clean Agent - <span>extinguish the fire by interrupting the </span>chemical reaction<span> of the fire triangle</span>
6) Dry Powder - extinguish the fire by separating thefuel<span> from the </span>oxygen<span> element or by removing the </span>heat<span> element of the fire triangle</span>
7) Water Mist - <span>extinguish the fire by taking away the </span>heatelement of the fire triangle
8) Cartridge Operated Dry Chemical - extinguish the fire primarily by interrupting the chemical reaction<span> of the fire triangle</span>
