a fixed amount of gas at 25.0 degrees Celsius occupies a volume of 10.0 L when the pressure is 629 torr. Use Charles law to calc

kirill [66]

Explanation:

Since pressure remained constant, we can eliminate P from the equation

$\frac{pv }{t} = \frac{pv}{t}$

Doing some algebra and converting temperature to Kevin by adding 273, you should obtain the same result.

A student is working with four beakers that each contains a clear liquid. Which set of procedures would be best to use to determ

telo118 [61]

Answer:

Observe odor, determine pH, determine density, determine boiling point

Explanation:

The correct procedures that would be best to use to determine whether a beaker contains only distilled water would be to observe the odor of the liquid in the beaker, determine the pH of the liquid, determine the density, and then determine the boiling point of the liquid.

<em>Water is generally odorless and has a pH of approximately 7 with a density of 1 kg/m3 and a boiling point of 100 </em> $^oC$ <em>. If the liquid in the beaker ticks all these conditions, then it can be established to be only distilled water.</em>
