A lot of these words are derived from the Greek or Latin roots that mean what the word is used to mean in English. It's helpful to look up the etymology or understand what these roots mean because they come up all the time and in different combinations. This way you can look at a word you've never seen before and know what it means by breaking it down into its component parts.
1. Surgical puncture to remove fluid = centesis
2. Inflammation = itis
3. Abnormal hardening = sclerosis
4. Surgical removal = ectomy
5. Vomit = emesis
6. Infection = sepsis
7. Involuntary contraction = spasm
8. Surgical opening = stomy
9. Specialist in = ologist
10. Process of recording = graphy
11. Instrument that records = graph
12. Oxygen = oxia
13. Seizure attack = ictal
14. Paralysis = plegia
15. Surgical repair = plasty
16. Disease = pathy
17. Study of = logy
18. Tumor = oma
19. Enlargement = megaly
20. Breathing = pnea
21. Malignant tumor = sarcoma

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>
