6NaN3+Fe2O3----->3Na2O+2Fe+9N2 a) What is the number of moles of iron produced if only 4 moles of NaN3 are consumed? b)Determine the mass of Na2O produced if only 25g of iron (iii) oxide are available. c)how many grams of sodium nitride are required to inflate an air bag with nitrogen gas to a volume of 46.0 Liters at 298k and 1.0atm d) How would the amount of sodium nitride change if the same airbag were to inflate at ta much higher elevation? more, less, same:?
34.62 mL sample of .1510 molar NaOH was needed to completely neutralize 50 mL of an H2SO4 solution. what is the concentration of the origional sulfuric acid solution?
The molar heart of neutralization from hydrochloric acid and sodium hydroxide is -57.3 kJ/mol. Use this accepted value to predict the heat evolved during the neutralization of 655mL of 1.00 M hydrochloric acid by 1.00 M sodium hydroxide
