When ammonia gas, NH3, is passed over hot liquid sodium metal, hydrogen gas, H2, is released and sodium amide, NaNH2, is formed as a solid product. What is the balancing Equation?
Determine the percent yield for the reaction between 3.74g of Na and excess O2 if 5.35g of Na2O2 is recovered
If a reaction mixture contains only N2O and NO2 at partial pressures of 1.0 atm each, the reaction will be spontaneous until some NO forms in the mixture.
The reaction of CrCl3 with liquid NH3 to give yellow [Cr(NH3)6]Cl3 often has a low yield, since the reaction tends to stop with the production of pink [Cr(NH3)5Cl]Cl2
What is the maximum mass of S8 that can be produced by combining 80.0g of each reactant? 8SO2+16H2S -> 3S8 + 16H2O
Determine the following characteristics of the titration curve for 25.0 mL of 0.400 M NH3(aq) titrated with 0.335 M HI(aq). (For NH3, Kb = 1.8x10-5.) Enter scientific notation as 1.23E4
kcl has the same structure as nacl face-centered. the length of the unit cell is 628 pm. the density of kcl is 1.984
The energy of a photo is 3.16 times 10^-19J. what is the wavelength of the corresponding light what is the color of this light
If the pressure is increased to 120 bar, the melting temperature increases to 375.88 K. Calculate DeltaHo fusion and Delta So fusion for this substance
Use satndard enthalpies of formation to calculate standard enthalpies of reaction for the reactions: a) C(graphic) + 2H2O(l) ---> CO2(g) +2H2(g) b) 2CH4(g) + O2(g) ---> 2CO (g) + 4H2(g) c) 2CO(g) + 2Cl2(g) ---> 2COCl2(g) d) Na2SO4 (s) +4CO(g) --->..
In solution in 6EB in Atkins 9th edition is not clear to me. The equation for the location of partile in the box is different from the one that is in the book.
a 81 l sample of dry air cools from 145c to -22c while the pressure is maintained at 2.85 atm. what is the final
At high pressures, real gases do not behave ideally. Use the van der waals equation and data in the text to calculate the pressure exerted by 18 gram of H2 at 20C in a 1.00L container.
