Please help with just 4 multiple choice questions?

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) -gt; Al2O3 (g) + HCl (g) + N2 (g) + H2O (g) Which of the following statements correctly describes this reaction?Chlorine is being oxidized.Aluminum is gaining electrons.Nitrogen is being reduced.Aluminum is a reducing agent.Question 2) Which of the following requires an oxidizing agent?Al -gt; Al3+2 O -gt; O2Cl2 -gt; 2 Cl-Ag+-gt; AgQuestion 3) Which of the following reactions is not an example of an oxidation-reduction reaction?3Br2 + 2Ga -gt; 2GaBr3H2S + Cl2 -gt; 2HCl + S2PbS + 3O2 -gt; 2PbO + 2SO2K2Cr2O7 + 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)?H2OMgClMgCl2H2O and MgCl2Please help i will greatly appreciate it

Answer:

it's your deodorant mixed with sweatyou just have to bleach the spots to get rid of them, there's not really a way to prevent them.
way too many ?s for one question - break 'em up Question 1)The space shuttle's solid rocket boosters use ammonium perchlorate and aluminum to create an explosive reactionThe unbalanced reaction can be seen below NH4ClO4 (s) + Al (s) - Al2O3 (g) + HCl (g) + N2 (g) + H2O (g) Which of the following statements correctly describes this reaction? Nitrogen is being reduced Question 2) Which of the following requires an oxidizing agent? Al - Al3+ Question 3) Which of the following reactions is not an example of an oxidation-reduction reaction? 3B 2PbS + 3O2 - 2PbO + 2SO2 Question 4) Which of the following represents the salt produced when the base magnesium hydroxide, Mg(OH) 2, reacts with strong hydrochloric acid (HCl)? MgCl2
