Make a fizzing volcano with facts and pictures of a volcano
By binary codes or a whole image depending on the description of the image.
It would be a chemical change
<u>Answer:</u> The molecules of oxygen gas that will be reduced to water are 42 molecules
<u>Explanation:</u>
We are given:

The substance having highest positive
potential will always get reduced and will undergo reduction reaction. Here, oxygen will undergo reduction reaction will get reduced.
will undergo oxidation reaction and will get oxidized.
Substance getting oxidized always act as anode and the one getting reduced always act as cathode.
The half reactions follows:
<u>Oxidation half reaction:</u>
( × 4)
<u>Reduction half reaction:</u>
( × 6)
<u>Overall reaction:</u> 
We are given:
Molecules of
= 28
By Stoichiometry of the reaction:
4 molecules of
reacts with 6 molecules of oxygen gas
So, 28 molecules of
will react with =
molecules of oxygen gas
Hence, the molecules of oxygen gas that will be reduced to water are 42 molecules
The volume<span> of </span>gas<span> because of the </span>increase<span> and decrease in the speed in which the molecules bounce around. ... Boyle's Law states that if temperature stays the same, the </span>amount of<span> space a </span>gas takes up will increase<span> if the </span>pressure<span> decreases. The </span>amount of gas<span> will take up less space if the </span>pressure<span> is increased. this would be the correct answer </span>
