Covalent solutes are considered non-electrolytes. What does this mean for the conductivity of the solution?
Non-electrolytes dissolve and completely dissociate in water providing
charged ions to conduct electricity.
Non-electrolytes dissolve and do not dissociate in water providing no
charged ions to conduct electricity.
Being a non-electrolyte refers the type of bonding and has no bearing on
conducting electricity
D)
Non-electrolytes do not dissolve in water and can not conduct electricity.

Can someone me with questions 15 to 17 plz.

Astudent is trying to create a table that compares hypotheses, theories, and laws. hypothesis theory law do scientific researchers formulate it? yes yes yes does it explain why things happen? yes yes no yes yes yes is it used to make predictions? no yes yes which of the following questions would most likely fill the blank in the table? is it an intelligent guess? is it newly formulated? is it based on observations? has it been proved?

Answer asap need to be answered by wednesday morning explain how a buffer works, using an ethanoic acid / sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
