Calculate the work done in kilojoules when 17.58 grams of copper reacts with excess nitric acid to form copper(ii) nitrate, nitrogen dioxide gas and liquid water in (a) a closed 200ml vessel and (b) an open beaker at 30oc. in addition, indicate if the system is doing work on the surroundings or the surroundings are doing work on the system. assume ideal gas conditions.

The atoms of a solid aluminum can are close together, vibrating in a rigid structure. if the can is warmed up on a hot plate, what happens to the atoms?

Suppose that a certain fortunate person has a net worth of $71.0 billion ($7.10×1010). if her stock has a good year and gains $3.20 billion (3.20×109) in value, what is her new net worth?
