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:
In interphase cell grow in size, DNA and protein synthesis takes place.
Explanation:
Interphase is the longest phase in the cell cycle and contain three sub phases and one checkpoint at the end of every checkpoint.
G₁ phase: In this phase the size of the cell increases and nearly becomes double, the raw material for DNA synthesis is synthesised e.g: mRNA and proteins(histone).
S phase: In synthesis phase replication of DNA takes place and amount of DNA become double so that it can be evenly distributed between daughter cells.
G₂ phase: In this phase cell continues to grow and synthesize proteins. cell prepare itself to move in mitotic phase so it can divide.
