Calculate the values of δg, δf and δsuniv for:
a) vaporization of 39 g of benzene at its boiling temperature (80.1 °c, 1 bar);
b) adiabatic expansion of 0.100 mol of an ideal gas, in vacuo (joule's experiment), with an initial temperature of 300 k, if the initial volume is 2.00 dm3 and the final volume is 6.00 dm3.
note: process a) is reversible, isothermal and isobaric.
data:
r = 8.314 j mol-1 k-1
1bar = 105 pa
m (c6h6) = 78.66 g mol-1

the answer is b. dilution

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
