By looking at the uncertainty of the bacterium's position, did the student have a valid point?

a. the student has a point. the uncertainty of the bacterium's position is much larger than the bacterium itself.

b. the bacterium's size and the uncertainty of its position are about the same magnitude.

c. the student should have little trouble finding the bacterium in the microscope the student is wrong.

d. the uncertainty of the bacterium's position is tiny compared to the size of the bacterium itself.

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
