What is the empirical formula of a hydrocarbon which produces 2.703 g CO2 and 1.108 g H2O when combusted?
Calculate the number of grams of Fe formed when 0.100 kg Fe2O3 of reacts.
Four atoms of iron (Fe) are to be combined with three molecules of oxygen (O2). How many total iron atoms and oxygen molecules will be combined during the formation of Fe3O4?
Determine the delta H of decomposition of 1.000 mole of solid KCIO3 into solid KCI and gaseous oxygen.
Show your calculations and determine the half-life of Tc-99 (in hours). (b)The delivery of a sample of Tc-99 from the reactor to the nuclear medicine lab of the hospital takes 3h.
caclculate the number of grams of Fe formed when 0.300kg of Fe2O3 reacts.
Is the reaction spontaneous?
If 0.345 moles are produced during a reaction and collected at a temperature of 294K and pressire of .981 atm what volume will the gas occupy?
1.0 mol of CaCN2 and 1.0 mole of water are mixed together: CaCN2 + 3 H2O → CaCO3 + 2 NH3 How much NH3 could be produced?
You are given the following data. S(s) + 3/2 O2(g) → SO3(g) ΔH = -395.2 kJ 2 SO2(g) + O2(g) → 2 SO3(g) ΔH = -198.2 kJ Calculate ΔH
Further studies will refine how much water is needed for endangered species protection. States hope it will be the 130-150 KAF initially agreed upon rather than the 415 KAF the FWS thinks it is. What happen if cooperative agreement fails?
A compound contains only carbon, hydrogen, and oxygen. Combustion of 10.68 mg of the compound yields 16.01 mg CO2 and 4.37 mg H20.
In a gas mixture the partial pressures are nitrogen 425 torr, oxigen 115 torr, and hellium 225 torr. What is the total pressure (atm) exerted by the gas mixture?
