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:
you should say " IF YOU HAVE A PROBLEM WITH WHAT'S BEING SERVED MAKE YOUR OWN FOOD."
Explanation:
In developed countries, most individuals die at <u>hospitals</u>, whereas in developing countries most individuals die at <u>home</u>.
In excessive earnings nations the bulk of humans die of simply vast organizations of reasons: cardiovascular sickness and cancer. As cardiovascular sicknesses declined, extra humans died from cancer. The proportion of deaths from maximum different vast reasons of dying increased, too. This has brought about more range in reasons of dying. Generally, wealthier international locations have a better common existence expectancy than poorer international locations, which may be argued to be done via better requirements of living, extra powerful fitness systems, and extra assets invested in determinants of fitness (e.g. sanitation, housing, education).
Thus, option a is the correct choice.

Research on group processes suggests that if group members start with similar opinions, they will support an option that is more extreme.
<h3>What is Research?</h3>
Research may be defined as the process of methodical examination into and analysis of materials and references in order to demonstrate facts and reach new conclusions.
The complete question is as follows:
A group of five health care professionals is presented with a complex system-based problem in a large hospital and asked to generate multiple possible solutions. Research on group processes suggests that:
- If group members get along, more options will be discussed and considered.
- The group is more likely to come up with an effective solution if there is a strong group leader.
- If group members start with similar opinions, they will support an option that is more extreme.
- On average, individuals working alone will produce fewer options than when working in a group.
Due to Group polarization, group members start with similar opinions, they will support an option that is more extreme. Statement A and B illustrate the mechanism of group thinking, while statement D represents social loafing.
Therefore, the correct option for this question is C.
