Question

7. Organie vs. Inorganic Compounds (10 points total) Given the compounds provided below, match each compound with the number and organic/inorganic characteristics listed in the table below.(10 points) correct oxidation Oxidation Number +4 Compounds to write in above: CoH120s, COs2, CH4, CHOCHO, HCO 8. Seismograph Data Analysis (6 points total) A seismograph detects the arrival of a P wave at 3:30 AM one morning followed by the arrival of an S wave at 3:33 AM. Assuming that the P wave travels at 8 km s and the S wave travels at 4 km s', estimate how far away the epicenter of the earthquake is from your location.

Explanation / Answer

Q7 ) [to solve for oxidation number of C, use oxidation numbers for H= +1 , O = -2]

C6H12O6 oxidation number = 0...........Organic

C03-2 oxidation number = +4.................Organic

CH4 oxidation number= -4.......................Organic

CHOCHO= +1........................organic

HCO2-= +2....................organic

Q8) Let the epicentre be d km away. and P waves takes t seconds to travel d kms,

so time taken by S waves = t+ 180 seconds

so

for P wave

Speed = Distance / Time

8= d/t

=> d= 8t---------------------------- equation 1

for S wave

Speed = Distance/ time

4= d/ t+180

using d from equation 1

4t + 720 = 8t

4t= 720

t= 180 seconds

therefore d= 8t = 180 * 8 = 1440 kms

therefore the epicentre is 1440 kms away.
