Determine the heat of mixing AH of sulfuric acid in water and the partial specific enthalpies of H2SO4 and H2O for a solution containing 65 mass-% H2SO4 at 298.15 K (25°C)
Also find the source voltage that would yield I = -8µA.
The overall reaction in a commercial heat pack can be represented as: 4Fe(s)+ 3O2(g) yields 2Fe2O3(s); delta H=1652 kJ
to find the force between the wires. Discuss the nature of the force when the wires carry currents in the same direction, and in opposite directions.
Under what circumstances and for what kinds of disabilities would the CLI be superior to or be preferred over the GUI?
__________ is the response curve for a step input signal from a reactor. 1. S-curve 2. C-curve
Hydrogen gives off 120. J/g of energy when burned in oxygen, and methane gives off 50. J/g under the same circumstances. If a mixture of 5.0 g of hydrogen and 10. g of methane is burned, and the heat released is transferred to 50.0 g of water at 2..
The heat of formation of (NH4)2SO3 (aq) at 25°C is -890.0kJ/mol, and that of NH4HSO3 (aq) is -760 kJ/mol. The heat capacities of all liquid solutions may be taken to be 4.0 J/(g*°C) and that of the flue gas may be that of nitrogen. Evaporation of ..
