1 - A balanced equation for the reaction is 3NH4ClO4 + 3Al -------> Al2O3 + AlCl3 + 6H2O + 3NO
2 - Ammonium perchlorate is the oxidizing agent while aluminum powder is the reducing agent.
Molar mass of aluminum oxide = 102 g/mol;
The molar mass of ammonium perchlorate =117.5 g/mol.
From the equation of reaction 3 moles of ammonium perchlorate react with 3 moles of aluminum to produce 1 mole of aluminum oxide.
That is 3 x 7.5 g of ammonium perchlorate reacts with g of aluminum to produce 102 g/mol of aluminum oxide. Also 150g.
150 g of ammonium perchlorate produces (150 * 102)/(3*117.5) g of aluminum oxide = 43.4 g of aluminum oxide.

Let us assume that the oxygen behaves as an ideal gas such that we can use the ideal gas equation to solve for the number of moles of O2.
PV = nRT ; n = PV/RT
Substituting the known values,
n = (0.930 atm)(93/1000 L) / (0.0821 L.atm/mol.K)(10 + 273.15K)
n = 3.72 x 10^-3 mols
At STP, the volume of each mol of gas is equal to 22.4 L.
volume = (3.73 x 10^-3 mols) x (22.4 L/1 mol)
volume = 0.0833 L or 83.34 mL
The reaction CFCl3 + UV Light -> CFCl2 + Cl does not need another reactant as with CFCl3 because the reaction itself is reactive to light. Note that there are reactions that are sensitive to light to form products and when this type of reaction are not exposed to light, no reaction occurs.
Answer:
See below in bold.
Explanation:
a) Yes because it is an ionic compound. Forms ions in water solution.
b) This is an alcohol with covalent bonds it does not ionise in water - no.
c) Yes this forms ions in water solution.
d) This is a sugar and does not ionise so No.
