Answer:
isn't it erosion

if i am wrong sorry have a good day
Answer:
Hydrogen Peroxide is known as a dental “debriding agent”. But when used on skin for minor wounds it will foam and turn surrounding tissue white. ... H2O2 decomposes easily to make water (H2O) and a single free oxygen atom which is looking for something to react with - like your skin.
Explanation:
Okay, to explain this you might have to grab a periodic table.
Do you have one? Good. Look at the most left side of the periodic table. The first group is the largest atoms in the periodic table. If you go to the right of the periodic table, the atoms get progressively smaller and smaller.
Why is this? Don't atoms get more electrons, and so become significantly bigger as they move to the right?
Although atoms do get more electrons as they go to the right, they also get more protons too. Protons pull on electrons and make atoms smaller. Because of this, going from left to right in a periodic table makes the atoms smaller and smaller, since more and more protons are added.
In this scenario, Aluminum is more to the right than Sodium, which means that it has more protons. Because of this, the protons in Aluminum pull more strongly on electrons than sodium, thus making aluminum smaller.
(Just a side note, going down in a periodic table makes the atoms bigger, since new shells are added every time)
Good luck! If you need any help, just ask :))

When we balance the given equation
POCl₃(g) ⇄ PCl₃(g) + O₂(g)
We will get
2POCl₃(g) ⇄ 2PCl₃(g) + O₂(g)
Solution:
Balancing the given equation
POCl₃(g) ⇄ PCl₃(g) + O₂(g)
Balancing the number of O
2POCl₃(g) ⇄ PCl₃(g) + O₂(g)
Balancing the number of P and Cl
2POCl₃(g) ⇄ 2PCl₃(g) + O₂(g)
We get the balanced equation
2POCl₃(g) ⇄ 2PCl₃(g) + O₂(g)
The reaction quotient will be
Qc = [product] / [reactant]
Qc = [PCl₃(g) + O₂(g)] / [POCl₃(g) ]

A change which would remove the source of this error is to: Test a fourth group, in which participants do not receive the mineral supplements.
<h3>What is a scientific method?</h3>
A scientific method can be defined as the various techniques that are adopted to observe, investigate, examine and study a particular thing while giving explanations on the basis of the evidence, theory, proof, hypothesis, or factual information they derived from the research work.
In this scenario, a claim was made by the company its mineral supplements can effectively prevent common cold. However, this claim was disputed by a scientist because there exist an error in the group setup.
<h3>How to remove an error in science</h3>
For this investigation, an effective and efficient way to remove this source of error would be by testing a fourth group, in which the mineral supplements is not administered to any of the participants.
