Answer:
14.8% of H2O2
Explanation:
Based on the redox reaction of H2O2/MnO4- is:
2MnO4- + 5H2O2 + 6H+ ⇄ 2Mn2+ + 5O2 + 8H2O
<em>2 moles of KMnO4 react with 5 moles of H2O2</em>
<em />
To solve this question we need to find the moles of KMnO4 until reach the endpoint. Using the balanced reaction, we can find the moles of H2O2 that must be converted to grams using its molar mass -Molar mass H2O2: 34.015g/mol-:
<em>Moles KMnO4:</em>
0.0297L * (1.4686eq/L) = 0.04362eq MnO4- * (1mol / 5eq) = 0.008723 moles MnO4-
<em>Moles H2O2:</em>
0.008723 moles MnO4- * (5mol H2O2 / 2mol MnO4-) = 0.02181 moles H2O2
<em>Mass H2O2:</em>
0.02181 moles H2O2 * (34.015g/mol) = 0.7418g H2O2
<em>%:</em>
0.7418g H2O2 / 5.0mL * 100
<h3>14.8% of H2O2</h3>
I don’t have two things I have one I would lower prices because someone people are not that wealthy as others so when they get sick or catch something they can’t go get help because they can’t afford it they want to say help every body but won’t help people because you want get money out of it that is just totally wrong.
Answer:
forensic linguist
Explanation:
From the available options provided the only individual position that does this would be a forensic linguist. The responsibilities of this position include analyzing language on text or recorded documents. They do this in order to understand and uncover different details within the document that may help law enforcement solve a crime. This also involves studying abbreviations used in text messages to identify the author, what the abbreviation means, in what context it is being used, hidden meanings, etc. All of which can be highly valuable in a criminal case.
