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:
All medicines must be stored in a cool, dry place, away from sunlight and moisture. Some medicines require special storage conditions such as in the refrigerator, or even the freezer. Such medicines can expire quickly if they are improperly stored at room temperature, becoming toxic or less effective.
Explanation:
Yes ur right omg thanks i like it
Answer:
Heat is transfered via solid material (conduction), liquids and gases (convection), and electromagnetical waves (radiation). Heat is usually transfered in a combination of these three types and seldomly occurs on its own.
Explanation:
The reported complication rate associated with traditional blind, or landmark-based, techniques for central venous catheter insertion is : 15% .
<h3>
What is Venus Catheter ?</h3>
A thin, flexible tube called a central venous catheter is inserted into the superior vena cava which is a large vein above the right side of the heart that is often found below the right collarbone. It is used to provide chemotherapy, injectable fluids, blood transfusions and other drugs.
In order to acquire central venous access for many patients who are suffering from critical conditions in Emergency, central venous catheterization, or CVC, is a crucial component of clinical therapy.
