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:
a. True
Explanation:
Cardiac plexus is a network of nerves present at the base of the heart. Sympathetic fibers of cardiac plexus originate from the cardiac nerves and they arise from the sympathetic trunk. Parasympathetic fibers arise from the vagus nerve's cardiac branches. In this way the heart is innervated by both sympathetic and parasympathetic fibers. Medulla in brain controls both the branches.
Answer:
Enhanced Injury and Reinjury Prevention: Sports medicine physicians have an in-depth understanding of how athletes use their bodies during practice and play; as such, they provide patients with expert advice and instructions on preventing injuries and avoiding re-injuring a previously damaged area.
A sports medicine specialist can provide athletes and active people with specific guidance regarding posture, performance, nutrition, and overall health. Sports doctors and physical therapists can help you learn about how to engage your muscles without injuring them.
Athletes look to sports medicine professionals for guidance regarding training techniques, injury prevention, diagnosis, and treatment of sports-related problems. Sports medicine professionals also treat some workplace injuries due to the similarity to sports injuries. Check out the latest professional opportunities.
