Yes, it was open at the top, but the column was very tall, thin and the water cooling the condenser was at a considerable low temperature: 10-11 oC. I'm not sure whether i have to use ethanol volatility or Schmidt Number to express why ethanol evaporated more.
Hi, i just perfomed a differential distillation experiment, the initial solution cointaned ethanol-water solution with 4.9% in mass it weighted 399.63g
Water Mass:381.25
Ethanol Mass:19.96
We distilliled the solution for 20 minutes and obtained two solutions, the distilled had 35.87g and the...
I found some information on what i needed to find the angles and i think i did it right, but i have one question, but first i'll explain my approach:
When the ball reaches its maximum height:(t1 seconds have passed)
Vy(t)=0=Vo*senb-gt==> vsenb=gt ==> t1=vsenb/g
also...
1. A basketball will be launched of height h and will hit the hoop that has a height of H. The horizontal distance between the ball and the hoop is d. Given an initial velocity Vo write both possible launch angles in function of h, H, Vo and d
2.
theta=tg^-1(Vy/Vx) (1)...
