Answer: Eating healthy is a postive way
Explanation:
Answer:
It works 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 out which is what the fire extinguisher does.

<u>Step 1: Define</u>
30 g SiO₂ (sand)
<u>Step 2: Identify Conversions</u>
Molar Mass of Si - 28.09 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of SiO₂ - 28.09 + 2(16.00) = 60.09 g/mol

0.499251 mol SiO₂ ≈ 0.50 mol SiO₂
Answer:
The answer is: Hydrolysis
Explanation:
Hydrolysis is the chemical method in which water molecule is added to a molecule, which leads to the cleavage of one or more chemical bonds in the molecule. In this reaction, the water molecule acts as a nucleophile and breaks down the large molecules like polymers into smaller molecules such as monomers. Hydrolysis reaction includes fragmentation, elimination substitution reactions.
