Glucose dissolves in water but doesn’t produce ions during dissolution process. Two (positive and negative) electrodes that were hooked up to a light bulb and external source of power were placed in an aqueous solution of glucose. What was observed during experiment?

a force of 500                  

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
