Answer: Medicine is a scientific field whose subject of research is the health and well-being of living whips.
Explanation:
Primarily medicine deals with the study of man and the treatment of man, but also of some animal species. Two principles are founded: theoretical research and practical, or often called a clinical policy. The academic and research law will enable a specific area, disease, congenital disability, or condition to be defined, studied in detail, and after the conclusion of tests performed. Concluded medical theory is most often put into a usable form through various educational processes, which will lead to the ultimate goal - to improve the health of living forms on which this theory will be applied.
Answer:
higher
Explanation:
If it contains a impurity that is insoluble it won't dissolve completely, the solution would be smaller than it is supposed to be, when compared to a compound without such insoluble impurity. Molecular weight determination won't be accurate because the molecular weight obtained will be higher as a result of the fact that the mass of the solute would include the actual solute that is changing the temperature and the excess mass of the impurity.
Molar mass = 133.34 g/mol
Answer:
A.
Explanation:
The leading zeros in c, d, and e are not significant. There is no zero in b. Just one left and all it's zeros are significant.
Answer:
mass of benzene in the lungs = 28.8 g of benzene
Explanation:
Volume of air breathed per hour = 500 mL * 12 * 60 = 360000 ml = 360 Litres of air
In 8 hours, volume of breathed air = 360 L * 8 = 2880 Litres of air
Concentration of benzene in air = 10 ppm
Note: 1 ppm = 1 mg per liter (mg/L)
10 ppm = 10 mg/L
Therefore, mass of benzene in the lungs in an 8-hour shift = 10 mg/L * 2880 L
mass of benzene in the lungs = 28800 mg
Converting to grams = 28800/1000
mass of benzene in the lungs = 28.8 g of benzene
