after Equilibrium NH3 gives 50% mole fraction(Means that after reaction is complete, the number of moles of NH3 formed from reaction occupies 50% of the total number of moles of all gases in the container) , the total volume of H2 and N2 in container before reaction is 3L. 1. Find mol...
Al alloys are widely used in automobiles, ships, and airplanes1,2, with rapidly growing relevance for weight reduction of (electrical) vehicles, to lower fuel consumption and environmental impact3. Besides their excellent strength-to-weight ratio, they are attractive for their high resistance when ...
How do you convert a pressure of 1.75 atm to kPa and to mmHg? Pressure Measurement Units The set of units of measurement used to measure pressure is relatively broad, ranging from the English system ({eq}psi= \frac{pounds}{inch^{2}} {/eq}) to the international system (Pascal)...

Hi Ktm! “The science is solid that greenhouse gases can intercept escaping heat” is correct. But “re-direct a portion of that heat back to earth” is not. To understand this, consider that at resonant CO2 frequencies around 667 cm^-1, complete saturation occurs within metres or hundreds...
To calculate the molecular mass of a compound, you need to know two things. The first is the molecular formula, and the second is the atomic mass number of each of the elements that comprise it. The atomic mass number for each element is listed in atomic mass units under its symbol in...
A simple example calculation will give you a feel for how to calculateQfor a reaction. Take the reaction: With the molarities: [CO] = 1 M, [H2O] = 1 M, [CO2] = 2M and [H2] = 2 M, and the equilibrium constantK= 1. Note that the stoichiometric constants for each of the compo...
The third confusion? That's not confusion, it's a lack of data. The fourth Cp = Cv + R; R is a constant for ideal gases. Ammonia, for example, is far from an ideal gas. hirschaplin(Petroleum) (OP) 8 Aug 23 13:53 Thank you guys, I think I have a solution to calculate Cp ...
To calculate the energy required to raise the temperature of a known mass of a substance, you use the specific heat formula: Q = m × c ×ΔT Qis the energy transferred in joules,mis the mass of the substances in kg,cis the specific heat capacity in J/kg degrees C, andΔTis the ...
You can also use the fraction of the gas that is distilled as a mole fraction to plot a graph of the temperature of the liquid, the liquid-vapor mixture and the vapor itself to determine the boiling point of the two or more components of the compound. Many distillation apparatus setups ...
