Please help i really need it?

Question 1)The space shuttle's solid rocket boosters use ammonium perchlorate and aluminum to create an explosive reactionThe unbalanced reaction can be seen belowNH4ClO4 (s) + Al (s) Al2O3 (g) + HCl (g) + N2 (g) + H2O (g) Which of the following statements correctly describes this reaction? Chlorine is being oxidizedAluminum is gaining electronsNitrogen is being reducedAluminum is a reducing agent.Question 2) Which of the following requires an oxidizing agent? Al -gt; Al3+ 2 O -gt; O2 Cl2 -gt; 2 Cl- Ag+-gt; AgQuestion 3) Which of the following reactions is not an example of an oxidation-reduction reaction? 3Br2 + 2Ga -gt; 2GaBr3 H2S + Cl2 -gt; 2HCl + S 2PbS + 3O2 -gt; 2PbO + 2SO2 K2Cr2O7 + KOH -gt; 2 K2CrO4 + H2OQuestion 4) Which of the following represents the salt produced when the base magnesium hydroxide, Mg(OH) 2, reacts with strong hydrochloric acid (HCl)? H2O MgCl MgCl2 H2O and MgCl2Please help i will greatly appreciate it

Answer:

use her stuff irritate her.i dont have a sister actually so i think i cant give good advice.sorry
