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>

Answer: Broca's area
Explanation:
Broca's area is primarily responsible for producing speech. It controls motor functions involved with speech production. It is a region in the frontal lobe of the dominant hemisphere, usually the left, of the brain.
People who have damage to this area of the brain can understand words but struggle to put them together in speech. Tony clearly has no problem processing what is being said but because of the damage he can't put his thoughts to words.
2 pints are equal to 64 U.S tablespoons so with that in mind we can get our answer.
There is 24 hours in a day and 24 divided by 6 hours means that the patient is taking the antacid 4 times a day.
2 tablespoons multiplied by 4 is equal to 8 tablespoons a day.
8 tablespoons multiplied by 8 days gets us to our magic number of 64 which is equivalent to the amount of 2 pints.
Answer= 8 days
