Understanding and using the ideal gas law

Calculate the work done when 50 g of iron dissolves in hydrochloric acid in (a) a closed vessel and (b) an open beaker.

Hint: Use the ideal gas law and equations to determine amount of work done when a gas expands.

Solution Preview

Step 1: Write a balanced chemical equation to describe the reaction

Fe (s) + 2HCl (aq) --> FeCl2 (aq) + H2 (g)

From the above equation, we know that one mole of gas is generated for each mole of ...
