Question

To Mrs. PhD (or anyone in chemistry), Can someone please help me answer these chemistry questions?
1. Identify and discuss the differences between the terms ‘theories,’ ‘laws,’ and ‘hypotheses.’ Describe ‘controlled conditions.’
2. Every measurement has a measurement uncertainty. Discuss how precise and accurate measurement can be achieved in spite of the inherent measurement uncertainty. You could use either of these two options:
•Take a ruler and measure the height of the textbook three times. Record the three measurements, and discuss the uncertainty in your measurements. Remember to report the smallest markings on your ruler.
•Take an egg and a measure the weight of the egg three times. Record the three measurements, and discuss the uncertainty in your measurements. Remember to report the smallest markings or “resolution” on your scale.
3. Respond to this problem statement: A robust first grader goes for swimming lessons three times a week, and he enjoys it thoroughly. During the first week of December, he develops an upper respiratory infection, starts coughing continuously, and has a high fever of 39°C. His condition remains the same even after five days of bed rest and conservative measures. Eventually, his mother decides to take him to the doctor who diagnoses it as an acute case of middle ear infection (otitis media), and prescribes amoxicillin for his treatment. He weighs 44lb, and the daily dose of amoxicillin for the treatment of the ear infection is 30mg/kg per day in divided doses every 12 hours.

• Determine the patient’s body temperature in Fahrenheit.
• Determine his dosage of amoxicillin in mg. per single dose.

Format

Response should be in a Word document, with details of the problem statement, the worked out calculation of the patient’s body temperature in Fahrenheit, and his daily dose of amoxicillin in mg. per single dose.
