The acid in a battery is an electrolyte.
Answer:
The volume of a gas approaches zero as the temperature approaches absolute zero.
Step-by-step explanation:
You may have done a <em>Charles' Law experiment</em> in the lab, in which you measured the volumes of a gas at various temperatures.
You plotted them on a graph, and perhaps you were asked to extrapolate the graph to lower temperatures.
Your graph probably looked something like the one below.
There is clearly an x-intercept at some low temperature.
Inference: The volume of a gas approaches zero as the temperature approaches absolute zero.
Answer:
31 moles
Explanation:
The balanced combustion reaction of the wax,
is shown below as:

As seen from the reaction,
1 mole of wax,
on combustion produces 31 moles of carbon dioxide, 
<u>Hence, moles of
when 1 mole of wax,
is burnt = 31 moles</u>
Two moles of potassium react with 2 moles of water to form two moles of potassium hydroxide and 1 mole of hydrogen gas. The number of moles of hydrogen gas produced is half the number of moles of water and potassium that react together.
The molar mass of...
