Two forces of F =⟨75/√2 ,−75/√2⟩ N and F =⟨150/√2 ,−150/√2⟩ N act on an object. Find the third force F3 that is needed to balance the first two forces.
A steam turbine operates at a boiler temperature of 450 K and an exhaust temperature of 300 K. What is the maximum theoretical efficiency of this system?
What daughter nucleus is formed when 234 93 Np undegoes electron capture?

The energy from the combustion of Hydrazine, N2H4, is used to power rockets into space in the reaction:
N2H4(g)+O2(g)=N2(g)+2H2O(l) delta H degree= -627.6KJ
How many killograms of hydrazine would be necessary to produce 1.0 X 10^8 KJ of energy?
Hint: One mole of N2H4 produces 627.6KJ of energy. How many moles (and then grams) are required to produce 1.0 X 10^8 KJ of energy.
The standard heats of formation for CH4, CHCl3, and HCl are -74.8, -132, -92.0 KJ/mole, respectively. Use this information to calculate the heat of reaction for the following:
CH4+3Cl2=CHCl3+3HCl
Calculate delta H degree for the process
2Al(s)+Fe2O3(s)=Al2O3(s)+2Fe(s)
Given that delta Hf degree of Fe2O3=-813.0KJ/mole and delta Hf degree of Al2O3 is -1655.0KJ/mole
Using a table of thermochemical data, calculate Enthalpy for the reaction.
CO(g)+1/2O2(g)=CO2(g)
