The Kj of heat that are needed to completely vaporize 1.30 moles of H2O if the heat of vaporization for water is 40.6 Kj/mole is calculated as below
Q(heat) = moles x heat of vaporization)
=1.30 mol x40.6 kj/mol= 52.78 Kj is needed
They can distill the muddy water. This can be done by placing it in a can, covered with pipes to collect the boiling water, and then collecting the distillate. The fuel will be used to provide energy for distillation and the solid particles in from the muddy water will remain in the can as residue.

<u>Answer:</u> The average rate of disappearance of A is
<u>Explanation:</u>
The given chemical reaction follows:
The average rate of the reaction for disappearance of A is given as:
Or,
where,
= final concentration of A = 0.11 M
= initial concentration of A = 0.91 M
= final time = 90 minutes
= initial time = 0 minutes
Putting values in above equation, we get:
Hence, the average rate of disappearance of A is
Answer:
A
Explanation:
because they are non polar so would not conduct electricity :)
