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>
<u>Insufficient </u><u>lung </u><u>capacity</u> is scba limitation would a firefighter be able to overcome through physical fitness and regular medical evaluations.
<h3>What are the limitations of respirator?</h3>
Full-face respirators are bulkier than half-masks and are frequently less pleasant to use. Full-face air purifying respirators cannot be utilized for all sorts of air contaminants because the type and capacity of the filters and cartridges used limit their use.
<h3>What is the capacity of SCBA?</h3>
SCBA Cylinders are available in five sizes to accommodate all <em>Self Contained Breathing Apparatus</em> (SCBA) and Emergency Escape Breathing Devices: 2L, 3L, 6.8L, 9L, and 10L. (EEBD).
The SCBA delivers compressed oxygen from the oxygen cylinder to the wearer via cylinder valves, pressure reducers, demand valves, and other components. The absorbing canister absorbs carbon dioxide from exhaled air, and the breathing bag resupplies oxygen.
