12. A 50.0 g sample of ice well below its freezing point, at an initial temperature of -30.09
C, is slowly heated until it is a gas well above its boiling point, to a final temperature of
130° C. Data is gathered where the independent variable is the time of heating and
the dependent variable is the temperature,

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

did anyone actually do this? like if anyone has submitted this i rly need .

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

a chemical change results in a new substance being formed; whereas a physical change will result in a different state of matter
