7 0

Answer:

93%

Explanation:

First write the balanced reaction

C3H8 + 5O2 --> 3CO2 +4H2O

2nd, find the theoretical yield

2L C3H8 (1mol/22.4L) (3 mol CO2/1 molC3H8) (22.4 L/ 1mol) = 6L

3rd, Find percent yield

%yield = (actual / theoretical) x100 = (5.7/6) x 100 = 93%

Covalent solutes are considered non-electrolytes. What does this mean for the conductivity of the solution? A) Non-electrolytes
iogann1982 [59]

Electrolytes are those which dissociates in solution and produces ions.

Ions can carry current,so Electrolytes conduct electiricity.

And non electrolytes are those which do not dissociate in solution and doesnt produce ions.

Since non electrolytes do not produce ions they cannot conduct electricity.

<u>Hence the right option is:</u>

B) Non-electrolytes dissolve and do not dissociate in water providing no charged ions to conduct electricity.
