How many gallons of canola oil would you need to use to fill up a 12 gallon tank for a diesel engine vehicle?
Assume the density of the biodiesel product is 0.88 g/mL and the density of canola oil is 0.92 g/mL. Use your % yield for the purposes of making this calculation 17.77 (-4 pts) Incorrect.

answer; economic order quantity;

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

the answer is c
