1) (6 points total) Report your results including: a) volume collected and % ethanol for each fraction (2 points), b) % yield of ethanol from molasses (2 points), and c) % yield ethanol from sugars, assuming approximately half of molasses is reactive sugars (2 points). Show at least one representative calculation for each part (a, b, and c). The relevant reaction is: C12H22O11 (sucrose) -> 4 CH3CH2OH 4 CO2

where's the diagram?

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.

metric time was an attempt to create a standard unit of time based off of 10, but it never took off an is not included in the metric system (si)

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
