Use the values given in the textbook (Appendix B) for the following question. Click here for a similar table. The reusable booster rockets of the space shuttle use a mixture of aluminum and ammonium perchlorate as fuel. A possible reaction is: 3 Al(s) + 3 NH4CIO4 (s) → Al2O3(s) + AlCl3(s) + 3 NO(g) + 6H20 (9) Given that the reaction enthalpy (as written above) is AH° = -2675.3 kJ, What is the standard enthalpy of formation (AHrº) for NH4CIO4(s)?...

2. The launch of the Space Shuttle was assisted by solid propellant rockets containing aluminum as the fuel and ammonium perchlorate, NH4CIO4, as the oxidizer; the two powders were bound together by a rubbery polybutadiene binder. Neglecting the binder (which is also a fuel) a balanced reaction equation is shown below. Use the listed values of the formation enthalpies to calculate Δ,H° for this reaction. 2A1(s) + 2 NH4Clo,(s) Al2O3(s) + N2(g) + → 3H2O(g) + 2HCl(g) +O2(g) -295.3 -1675.7...

step by step clearly
The solid-fuel rockets of the space shuttle are based on the following reaction between ammonium perchlorate and aluminum: 3 NH4CIO4(s) + 3 Al(s) = Al2O3(s) + AlCl3(g) + 3 NO(g) + 6 H2O(g) If either reactant is in excess, unnecessary mass will be added to the shuttle, so a stoichiometric mixture is desired. What mass of each reactant should be used for every kilogram of the fuel mixture?

The reaction that takes place in the reusable solid rocket booster for the space shuttle is shown by the following balanced equation: 3 Al (s) + 3 NH4ClO4 (s) 6 Al2O3 (s) + AlCl3 (s) + 3 NO (g) + 6 H2O (g) What volume of NO gas is formed from the reaction of 100 kg of Al (s) if the reaction is run at 1.03 atm and 300EC? What is the mass, in kg, of water (MM = 18.015...

The solid rocket boosters of the space shuttle employed the following oxidation/reduction reaction: 10 Al (s) +6NH4CLO4 (s) --> 4Al2O3 (s) +2AlCl3 (s) + 12 H2o (g) + 3N2 (g) ?Hf 0 for NH4ClO4= -295.3 KJ/mol Al=0 KJ/mol Al2O3= -1676 KJ/mol AlCl3= -704.2 KJ/mol H2O= -241.82 KJ/mol N2= 0 KJ/mol Calculate the standard enthalpy of this reaction. How much energy is released when 100,000 kg of ammonium perchlorate (and excess aluminum) is burned?
