Need help with science-classifying chemical reactions?

i need help badly i tired and i cant do it. this is what its asking classify each of the following chemical reactions as a synthesis(S), decomposition(D), single replacement(SR), double Replacement(DR), or neutralization(N).Then WRITE A BALANCED EQUATION for each of the word equations. these are the... show more i need help badly i tired and i cant do it. this is what its asking
classify each of the following chemical reactions as a synthesis(S), decomposition(D), single replacement(SR), double Replacement(DR), or neutralization(N).Then WRITE A BALANCED EQUATION for each of the word equations.
these are the questions
5.lead(II) nitrate + ammonium sulphide = cadmium(II)sulphide+ammonium nitrate
6.magnesium+silver nitrate = silver+magnesium nitrate
7.cadmium(II)nitrate+ammonium sulphide = cadmium(II)sulphide+ammonium nitrate
8.tin(IV)hydroxide+hydrogen bromide = water+tin(IV) bromide
9.sodium+oxygen = sodium oxide
10.sodium nitride = sodium+nitrogen
11.calcium hydroxide+phophoric acid = water+calcium phosphate
12.barium chloride+sodium carbonate = barium carbonate +sodium chlroide
13.zinc+nickel(II)nitrate = zinc nitrate + nickel
14.antimony+iodine = antimony(III)iodine
15.carbon dioxide = carbon+oxygen
16.iron(III)sulphate+lead = lead(II)sulphate+iron
17.barium nitrate + ammonium carbonate = ammonium nitrate+barium carbonate
18.zinc hydroxide+hydrochloric acid = water+zinc chloride
19.ammonium carbonate+magnesium chlroide = ammonium chloride + magnesium carbonate
20.rubdium hydroxiude+sulphuric acid = water +rubidium sulphate
i really appreciate this alot thank you
