Kinda long but I really need your opinions thank you.....

See I am currently a third year Chemical Engineering student(incoming 4th year this coming semester but because I failed a crucial subject I'll be delayed). I don't know if I should shift course now or what. I am actually thinking of shifting to Mechanical Engineering.I am really confused now. Well I have already repeated several subjects due to some failures but everytime I repeat a subject, I find out that I could really do it because during my second take I could get more than a passing mark in those subjects even without studying the lessons again. People (who graduated from chemical engineering and others too) say that Chemical Engineering is one of the toughest courses there is but I shouldn't shift courses anymore because I have a bright future there .But because I have failed a subject again I don't know if I should shift already. I don't really like some of the people in our department including some faculty too. I guess I am being intimidated. My mother says that she will support me in whatever decision I will make but my father doesn't seem to support me both ways. I fail he gets mad, I shift he gets mad its making me more confused though.

I really don't want to fail anymore. But repeating my subjects, I know I can do it. If I shift I'll have to adjust again. If I don't I might get more delayed because of failures. I don't really even know what a Chemical engineer does.... What if I don't like the future I'll be? If I shift, what if it is not what I really want??? PLEASE HELP ME DECIDE.. enrollment is just a few days and I really don't know what to do.. I just feel so lost

By absorption in silica gel, you are able to remove all .72 lb of the H2O from moist air at 60 deg F and 29.92 inHg. The same air measures 1000 ft^3 at 70 deg F and 32.0 inHg when dry. What was the relative humidity of moist air? Saturated air at 60 deg F has a vapor pressure of .52 inHg...

** I found the no. of moles of H2O which was .04 lbmol and the mol of dry air which is 2.7663 I don't then found their respective pressures.. what do I do next? thanks

How can I find the current in each of the branch of the circuit?? I'm just a bit confused thanks :)) Here's the circuit link http://img832.imageshack.us/img832/4049/2013031719... (sorry for the wrong orientation -_-)

A 16-ohm resistor is connected in series with a parallel combination of 2 resistors, one of which has an ohmic value of 48 ohms, the other one R , being unknown. What is R if the power taken by the 16-ohm unit is equal to the power in the parallel-connected pair of resistors?

How can I get the total resistance and the missing resistance of this circuit given the following data:

R1=18 R2=9

R3= 16

R4= 14

R5= 7

I2= 2.5A

And E=97.5v

How would I solve 2 unknowns in 3 equations? For instance in a Ramsay-Shields equation 3 conditions are given and the unknown are k and tc

***Ramsay Shields equation= (M/P1)^2/3=k(tc-t1-6) 3 conditions are given and we have to solve for the value of k and tc

A copper wire whose diameter is .162 in has a resistance of .4 ohm. If the wire is drawn through a series of dies until its diameter is reduced to .032 in, what is the resistance of the lengthened conductor? Assuming that the resistivity stays constant

5. At 0 deg celcius under a pressure of 1000 mmHg, a given weight of N2 occupies a volume of 1 Liter. At -100 deg celcius the same weight of gas under the same pressure occupies a volume of .6313 Liter. Calculate the absolute zero in degrees centigrade (I don't really know absolute zero means)

Assuming that dry air contains 79% N2 and 21% O2 by volume, calculate the density of moist air at 25 deg. celsius and 1 atm pressure when the relative humidity is 60%. The vapor pressure of water at 25 deg celcius is 23.76 mmHg

At 27 deg. celcius, 500 cc of H2, measured under a pressure of 400 mmHg and 1000 cc of N2, measured under a pressure of 600 mmHg, are introduced into an evacuated 2-L flask. Calculate the resulting pressure ( I'm really lost here -_- )

How can I get the centroid of a circular segment and can someone give me an example??? ( I don't know when I would use the angle in radians and in degrees) thanks a lot :D

A .500g of pure CaCO3 is dissolved in water to which 50 mL of HCl solution have been added. The solution then requires 6.20 mL of NaOH solution of which 1.000 mL can titrate ( I guess that's what the symbol meant) 1.010 mL of the HCl. What is the normality of each of the two solutions? (MM CaCO3=100 g/mol)

1. Of the two general types of acetylene derivatives, R-C=C-H and R-C=C-R which would be expected to give a positive test when the reagents Ammoniacal Cuprous Chloride and Ammoniacal Silver nitrate are used?

b. What structural effect or feature is required for the reaction?

c. What is the function of ammonia in these reactions?

2. (Just verifying) What volume of acetylene measured at standard conditions could be obtained from 10 grams of calcium carbide?

*I got the answer 3.8690L... I used .1560mol for n... I'm not sure if I was on the right track xD

thanks :D

1. 800 kg/h of halibut livers containing 23% oil is extracted with 570 kg/h of pure ether. The extracted liners is analyzed and found to contain 1.12% oil, 32.96% ether and 65.92% oil free liners. Find the composition and the weight of extract and percentage recovery of oil

2. Soybean which is used for making textured vegetable proteins contains 15% by weight oil. Suppose that 300lb of solvent containing 2 oil is used to extract oil from 500 lb soybean. The solvent and the soybean flakes are mixed thoroughly and the solution is drained. The flakes are still wet with solution and the oil in the solution is 2lbs. Find the weight composition (% oil ) of the solution

The tow truck's front wheels will be lifted off the ground if the moment of the load W about the rear axle exceeds the moments of the 31,000-N weight of the block. Determine the largest W that may be safely applied

the book says the answer is 3007.9 N but I can't come up with the answer. I keep on geting 24,000+ N

thanks

What are organic compounds found in the household that changes when heated....for example sugar. thanks :)

how do I find the inverse laplace of 1?? thanks :D
