This method is reasonably accurate, but the cost of deploying this method is high, especially when a livestock building is provided with a large number of ventilation fans as may be the case in poultry livestock buildings. Here the CO2 mass balance method may provide...关键词:...
Calculate the volume of a unit cell and volume of atoms within a unit cell for FCC and BCC. After passing a current of 0.375 Amps for 1.2 hours through the cell below, calculate the mass of copper deposited. Pt, H_2(1 bar)| H^+ (1m)||Cu^+...

To set the scene: I performed a synthesis of copper oxalate complex, which I had to analyse by titration against [KMnO4] = 0.02024M to determine the percent by mass of oxalate in my sample. My calculation thus far: 2MnO4- + 5C2O42- +16H+ 2Mn2+ + 10CO2 + 8H2O ...
Calculate the density, in grams per liter, of carbon dioxide ({eq}CO_2 {/eq}) gas at STP. Density: The density is an intrinsic parameter. This would be a quantity that reflects the mass contained per unit volume of substances. This means that the expression of the density...
Molar Mass of H2O:18.02 g/mol ElementSymbolAtomsMass % HydrogenH211.2% OxygenO188.8% Relate the moles of standard solution to the moles of unknown solution. Because this is a neutralization reaction, assume that the standard solution is the base (OH- ions). You calculated the moles of base...
Calculate the mass of calcium hydrogen carbonate required to produce 2.0 x 103 L of gaseous carbon dioxide at NTP conditions. The equation for this reaction is: Ca(HCO3)2 + 2HCl to CaCl2 + 2H2O + 2CO2. a) 7.24 x 10 -3 g b) 2.74 x 103 g c) 7.42 x 103 g d) ...
Well, it's been a while sinve I've had to do one of these calculations. Does anyone know what the mass flow rate of CO2 is in lbs/hr if you have 15 MMSCFD flow rate? It's in gaseous form and somewhere near 100-150 F...thanks! Replies continue below Recommended for you Fluid...
