ASAP One renewable energy source is Ethanol.
Regular gas contains up to 10% ethanol
E-85 for Flex Fuel vehicles is 85% ethanol
Most ethanol in the U. S. comes from corn
Problem:
To make ethanol you need to dissolve 6kg of sugar in 21L of water, mix.
Then add 260g of yeast to mixture. Wait 7-10 days and then distill the ethanol.
How much sugar and yeast do you need to mix with 250ml of water? You must show
your work.

An example of technology is the a. addition of a side group to an organic molecule during synthesis. b. use of a new antibiotic to fight an infection. c. measurement of iron concentration in a water sample. d. study of atomic fusion reactions

Which is a chemical property of iron? a. it forms iron oxide (rust) when exposed to moisture and air. b. it is a gray–black metal that is hard to the touch. c. it has a melting point of 2795°f (1536°c). d. it is a good conductor of heat

The ozone molecule o3 has a permanent dipole moment of 1.8×10−30 cm. although the molecule is very slightly bent-which is why it has a dipole moment-it can be modeled as a uniform rod of length 2.5×10−10 m with the dipole moment perpendicular to the axis of the rod. suppose an ozone molecule is in a 8000 n/c uniform electric field. in equilibrium, the dipole moment is aligned with the electric field. but if the molecule is rotated by a small angle and released, it will oscillate back and forth in simple harmonic motion.what is the frequency f of oscillation?
