Answer:
a contaminant concentration
Explanation:
The concentration of the ingested contaminant determines the toxicity potential of the contaminant. All chemicals are acute toxicants if they are ingested in large amounts. The target organs and mechanism of action of these toxicants may vary but their potential to become toxic depends entirely on their absorption concentration. For example, Ethanol causes CNS depression but may lead to Liver cirrhosis if the concentration in body is very high.
Significant drug interactions that occur with antiviral drugs arise most often when they are administered via systemic routes such as intravenously and orally.

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:
B. system
Explanation:
An example of a system would be the circulatory system helps circulate blood carrying nutrients to organs and waste material away from organs. It includes the organs - heart, blood vessels and lungs.
