The overall reaction in a commercial heat pack can be represented as: 4Fe(s)+ 3O2(g) yields 2Fe2O3(s); delta H=1652 kJ
a. How much heat is released when 4.00 mol iron is reacted with excess O2?
b. How much heat is released when 1.00 mol Fe2O3 is produced?
c. How much heat is released when 1.00 g iron is reacted with excess O2?
d. How much heat is released when 10.0 g Fe and 2.00 g O2 are reacted?
Estimate the heat exchange area required for an evaporator that concentrates 4000 kg/h of apple juice by removing 40% of the water content. Low pressure steam at 120 °C is available as a heat source.
Under these conditions, what is the depreciation cost during the sixth year of the total life if straight-line depreciation is used?
1. It is desired to use 28.32 m 3 /min of air (metered at a pressure of 101.3 kPa and 294.1 K) in a process. This amount of air which is at rest enters the fan suction at a pressure of 741.7 mm Hg and a temperature of 366.3 K and is discharged at a p..
Develop the four equations and describe the meaning of each term.
Assume you have gas in a cylinder equipped with a piston. There are weights on the piston creating pressure down on the gas.
Assume that the absorption coefficient is 0:1 cm-1, the scattering coefficient of a 5-cm thick tissue is 100 cm-1, the scattering anisotropy is 0.9, and the wavelength of light is 0:5 mm. Calculate the light fluence rate 5 cm from the source.
Show the implementation of the same synchronous counter using D flip-flops.
A factory is producing tablets. It is required to design a system such that: The bottles moves till it reach the position shown (A) and 50 tablets are dropped in
Following a procedure analogous to that in Example 5.2, obtain an expression for the coefficient of thermal expansion based on the van der Waals equation of state. Use the result to calculate the value of β for oxygen at 20 °C, 30 bar.
Determine the current I through the 10-Ω resistor of the circuit of Figure P2.2.5 by employing the node-voltage method. Check by mesh analysis.
