The correct answer is Thoracic Cavity
Explanation:
In the human body, the thoracic cavity is located above the abdomen and below the neck. This cavity includes vital organs such as the lungs and the heart. Moreover, this cavity is surrounded by bones such as the ribs. Besides this, while driving the thoracic cavity is expected to be in front of the steering wheel because the steering wheel is always in front of the chest of the driver. Due to this, if William's body slammed into the steering wheel during the accident is likely this cavity was the one most affected due to its position.
Answer:
There will be less animal life in lake Raymond in the next year.
Explanation:
In the year with heavy rain, this has caused the depth of Raymond lake to be increased. This will bring an increase in the growth and survival of more water plants and animal species.
In the second year where there is a decrease in the water level, the animals and water plants will face problems. The worst hit are those plants and animals species that lives at a much deeper path of the lake with the least sunlight or any external factors that are now going to be more exposed due to low water level..
Answer:
Symptoms of malaria include fever and flu-like illness, including shaking chills, headache, muscle aches, and tiredness. Nausea, vomiting, and diarrhea may also occur. Malaria may cause anemia and jaundice (yellow coloring of the skin and eyes) because of the loss of red blood cells.
Explanation:
Requires a medical diagnosis
Symptoms are chills, fever, and sweating, usually occurring a few weeks after being bitten.
People may experience:
Pain areas: in the abdomen or muscles
Whole body: chills, fatigue, fever, night sweats, shivering, or sweating
Gastrointestinal: diarrhea, nausea, or vomiting
Also common: fast heart rate, headache, mental confusion, or pallor
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>
