5.00 moles of N2 and 8.00 moles of H2 are placed in an empty container, the container is heated to 887 degrees Celsius, and a catalyst is added that catalyzes the rxn. of these gases to form NH3 as the only product. At equilibrium 1.00 mole of NH3 is found to be present. Find number of moles N2 and moles H2 present at equilibrium.
* I think that the concentrations of the reactants changes by 1 mole but I'm not enitrely sure if that is correct.

Research on performance measurement in service businesses, reported in Management Accounting, found that ‘performance measurement often focuses on easily quantifiable aspects such as cost and productivity whilst neglecting other dimensions which are important to competitive success’.
You are required:
(a) To explain what ‘other dimensions’ you think are important measures of performance;
(b) To describe what changes would be required to traditional information systems to deal with these ‘other dimensions’

A triangular concrete (n=0.013) channel having a side slopes 2H:1V is designed to carry a flowrate of 200 cfs at a normal depth. The channel bed slope is 0.1%.
a) Determine the state of flow (regime).
b) Farther downstream the channel slope changes to 0.9%. Determine the new state of flow. c) Classify channel slope. Sketch the water surface profile from upstream to downstream sections.

Write about why caring for our common home is the following: 1) a moral issue that requires knowledge, an examination of conscience, and changes in how we exercise free-will and evaluate actions; and 2) an issue that requires efforts aimed at social justice, that is, altering prevailing structures and ways of acting.
In addition, explain how the global lack of care for the world/environment could become a personal sin a

How to size an I section under shear bending? Stress calculation should be done at which points, why? Which of the parameters that affect stress are more critical? What changes when the section is L, rectangular, or U? What additional inspections should be made for a safe design or what principles should be used for the check? How to choose the section or point to be checked? Explain with formulas, figures, and equations.
