Acetaminophen contains 8 carbon atoms, 9 Hydrogen atoms, 1 Nitrogen atom and 2 Oxygen atoms.
The molecular formular is given as; C8H9NO2
b. What is the hybridization state of each C, N, and O atom?
From the image attached;
All the carbon atoms in the benzene ring has hybridization of sp2.
The carbon that is doubly bonded (carbonyl) to the oxygen has hybridization of sp2
The last carbon to the right has hybridization of sp3
The hybridization of nitrogen in the compound is sp3 hbridized.
Oxygen atom in alcohol is sp3 hybridised
Oxgen in the carbonyl group is sp2 hybridized.
Answer:
e) intensity of precipitation f) location of precipitation.
Explanation:
Doppler radar can see not only the precipitation in a thunderstorm (through its ability to reflect microwave energy, or reflectivity), but motion of the precipitation along the radar beam. In other words, it can measure how fast rain or hail is moving toward or away from the radar. From a volume scan (a series of 360-degree sweeps, each tilting a little higher than the last), forecasters can get a detailed look at structures and movements in storms close to the radar. The farther away from the radar a storm is, the more coarse the view, because: 1) The radar beam spreads out with distance, like a flashlight beam, causing small features to be missed at a distance; and 2) The beam shoots straight as the earth curves away from beneath -- a horizon that forces the radar to miss more and more of the low and middle levels of a storm with distance.

Answer:
V=0.430 Liters
Explanation:
First off you need to convert ml to l and celsius to kelvin, in order for them to be in the S.I.
So, 350.0mL is 0.350 L and 23.0 C is (273.15+23=) 296.15 K (you can ignore the 0.15)
From the equation pV=nRT, lets name this equation (1), we can tell that the number of moles, pressure, and R, stay the same. The only thing changing is the volume, and temperature.
With the information given, let's figure out the pressure. From equation (1) if we solve it for the pressure of the gas, p=nRT/V => p=nR*296.15/0.350 => p=846.15 *nR
Now, we have to figure out the volume of the gas at 90.0 C (363.15 K), and solve equation (1) for volume, using the pressure we previously found.
v=nRT/p => v=nR*363.15/846.15*nR => (the nR's from top and bottom go away) v=0.429 L
Since we used 273.15 for the conversion of celsius to Kelvin, we could round up the number to
V=0.430 Liters
