Beyond simple thermal decomposition, an even more effective means of obtaining energy from NH4ClO4(s) \rm NH_4ClO_4(s) is to mix

this oxidizer with a fuel. When NH4ClO4(s) is employed in solid-fuel booster rockets, it is packed with powdered aluminum. The powdered aluminum is the fuel, and the ammonium perchlorate is the oxidizer. Two of the reactions occurring on ignition are
6NH4ClO4(s)+10Al(s)2NH4ClO4(s)+2Al(s)??5Al2O3(s)+6HCl(g)+9H2O(g)+3N2(g),?H1=?4392.5 kJ

Al2O3(s)+2HCl(g)+3H2O(g)+2NO(g),?H2=?1172.6 k

Which of the following statements are correct?

Check all that apply.

a.All nitrogen atoms lose three electrons in both reactions.

b.Chlorine is reduced from + +7 to ? -1 in both reactions.

c.Reaction 2 produces more energy per gram of Al \rm Al.

d.The thrust produced by the formation of gaseous products is greater per mole of ammonium perchlorate in Reaction 2.

Answer:

b.Chlorine is reduced from + +7 to ? -1 in both reactions.

Explanation:

From the reactions shown, the reaction equations are redox. It is clear that in both reactions, chlorine has oxidation numbers of +7 on the lefthand side of the reaction equation and -1 on the right hand side of the reaction equation. This buttresses the point that the reactions are redox as earlier stated.

Hence this is the only true statement is that;.Chlorine is reduced from + +7 to ? -1 in both reactions.

Plz someone help, really struggling
frez [133]

Answer:

22.9 Liters CO(g) needed

Explanation:

2CO(g)     +   O₂(g)    =>    2CO₂(g)

? Liters          32.65g

                 = 32.65g/32g/mol

                 =   1.02 moles O₂

Rxn ratio for CO to O₂ = 2 mole CO(g) to 1 mole O₂(g)

∴moles CO(g) needed = 2 x 1.02 moles CO(g) = 2.04 moles CO(g)

Conditions of standard equation* is STP (0°C & 1atm) => 1 mole any gas occupies 22.4 Liters.

∴Volume of CO(g) = 1.02mole x 22.4Liters/mole = 22.9 Liters CO(g) needed

___________________

*Standard Equation => molecular rxn balanced to smallest whole number ratio coefficients is assumed to be at STP conditions (0°C & 1atm).

When adjusted for any changes in δh and δs with temperature, the standard free energy change δg∘t at 2400 k is equal to 1.22×105
rosijanka [135]
When adjusted for any changes in δh and δs with temperature, the standard free energy change δg∘t at 2400 k is equal to 1.22×105j/mol, then the equilibrium constant at 2400 k is 2.21×10−3. The answer to the statement is 2.21×10−3.
