Ammonium nitrate can decompose into dinitrogen monoxide gas and water. Write complete thermochemical balanced equation. The ΔH for the decomposition releases 37.0 KJ.
Consider the following statements: "Heat is a form of energy, and energy is conserved. The heat lost by a system must be equal to the amount of heat gained by the surroundings.
The process produces a net amount of work equal to 4,500 J/mol and it exchanges an unknown amount of heat with the surroundings. Determine the amount of heat exchanged with the surroundings. Is this heat absorbed or rejected by the system?
find the other resistor values needed, and calculate the maximum analog output voltage, the minimum analog output voltage, and the smallest detectable analog output voltage if Vref = -15 V.
Find the width (in the x-direction) of the Rankine oval created by the flow, and the pressure difference between a point at infinite distance upstream and the point of coordinates (1,1).
Design a sieve plate column to perform this separation, for a feed rate of 10,000 kg/hour. Treat the feed as a binary mixture of ethanol and water. Take the feed temperature as 20 °C. The column will operate at 1 atmosphere.
Calculate the instantaneous and rms values of the voltage induced in a 150-turn coil on the armature, if the axial length of the armature and its inner diameter are both 100 mm.
One can now remove this codeword and apply the same decoding rule to the remaining, shorter concatenation of code words.
The standard enthalpy of formation of H2O(l) at 298 K is 285.8 kJ/mol. Calculate the change in internal energy for the following process at 298 K and 1 atm: H2O(l) yields H2(g)+12 O2(g);
Suppose that there are n identical chip producers, let D(p) be the demand function, and let p(a) be the competitive equilibrium price. Calculate (dplda) and its sign.
With a load of 0.8 power factor lagging, what kVA load can be supplied without exceeding the current rating of any winding? Determine the efficiency at this load.
To avoid such an undesirable state (because it causes the logic state of the circuit to fluctuate), an SRFF is placed between the switch and the circuit, as shown in Figure P6.1.50. Explain the operation as a buffer.
Volume of Air Required for Combustion of a Natural Gas Mixture, A natural gas has the following analysis by volume:
