Question

Помогите пожалуйста: Осуществить цепочку превращений:1) S—FeS—SO2—NaHSO3—SO2 2) P—P2O5—HPO3—H3PO4—Na3PO4—Na2HPO4—CaHPO43)N2—NH3—N2—NO—NO2—N2O4—NaNO2

Answer 1

1) s+fe=fes
4fes+7o2=2fe2o3+4so2
so2+naoh=nahso3
nahso3=so2+naoh
2) 4p+5o2=2p2o5
p2o5+h2холодная=2hpo3
hpo3+h2o=h3po4
h3po4+3naoh=na3po4+3h2o
na3po4+naoh=na2hpo4
na2hpo4+caoh=cahpo4+2naoh
3)n2+3h2=2nh3
4nh3+3o2=2n2+ 6h2o
n2+o2=2no
2no+o2=2no2
no2=n2o4+o2
n2o4+nabr+naoh=nano2+nabro3+h2o

Answer 2

Chemical Reaction Chains

Let's break down the transformation chains step by step:

1) S—FeS—SO2—NaHSO3—SO2+2 - Sulfur (S) reacts with iron (Fe) to form iron sulfide (FeS). - Iron sulfide (FeS) reacts with oxygen (O2) to produce sulfur dioxide (SO2). - Sulfur dioxide (SO2) reacts with sodium bisulfite (NaHSO3) to form sulfurous acid (H2SO3) and sodium sulfate (Na2SO3). - Sulfurous acid (H2SO3) then decomposes to produce sulfur dioxide (SO2) and water (H2O).

2) P—P2O5—HPO3—H3PO4—Na3PO4—Na2HPO4—CaHPO4 - Phosphorus (P) reacts with oxygen (O2) to form diphosphorus pentoxide (P2O5). - Diphosphorus pentoxide (P2O5) reacts with water (H2O) to produce phosphorous acid (H3PO3). - Phosphorous acid (H3PO3) further reacts with water (H2O) to form phosphoric acid (H3PO4). - Phosphoric acid (H3PO4) reacts with sodium hydroxide (NaOH) to yield sodium phosphate (Na3PO4). - Sodium phosphate (Na3PO4) reacts with hydrochloric acid (HCl) to produce disodium hydrogen phosphate (Na2HPO4). - Disodium hydrogen phosphate (Na2HPO4) reacts with calcium chloride (CaCl2) to form calcium hydrogen phosphate (CaHPO4).

3) N2—NH3—N2—NO—NO2—N2O4—NaNO2 - Nitrogen gas (N2) reacts with hydrogen gas (H2) under high temperature and pressure in the presence of a catalyst to produce ammonia (NH3). - Ammonia (NH3) can be oxidized back to nitrogen gas (N2) or further oxidized to form nitric oxide (NO). - Nitric oxide (NO) reacts with oxygen (O2) to produce nitrogen dioxide (NO2). - Nitrogen dioxide (NO2) dimerizes to form dinitrogen tetroxide (N2O4). - Dinitrogen tetroxide (N2O4) reacts with sodium hydroxide (NaOH) to yield sodium nitrite (NaNO2).
