ES 6- HCl 0.0 / 5 ? ChemistryThe Periodic TableASOCR Created by: anabobCreated on: 21-01-18 19:12 do high atom economies have more or less waste? less 1 of 14 how do yu calculate the atom economy? formula mass of desired product/formula mass of all reactants X100 2 of 14 how can HCl acid be made as a co-product? first stage of manugfacture of PVC is ethene + chlorine to give chloroethene and hyrogen chloride. Pass it through water to get HCl acid 3 of 14 what is the equation for this? CH2ClCH2Cl----> CH2CHCl +HCl 4 of 14 are fluroide ions good reducing or oxidising agents? oxidising agents 5 of 14 whats formed when NaCl/NaF + H2SO4 react? NaHSO4 + HCl/HF 6 of 14 what happens to thermal stability as you go down group7? decreases 7 of 14 why does HI get broken down into its elements at a lower temp than HCl? bond strength decreases down group 7 8 of 14 when hydrogen halides are heated in a lab, which halide gases can be formed? Br2/I2 9 of 14 are hydrogen halides very soluble and acidic in water? yes 10 of 14 how can you show that Hcl/HBr/HI are strongly acidic? HCl-->H+ + Cl- or H2O+HCl---->H3O+ + Cl- 11 of 14 what happens if a glass rod dipped in conc. ammonia solution is placed int he hydrogen halide? white cloud of ammonia halide 12 of 14 what equations hows the reaction of ammonia and HCl? NH3 + HCl----> NH4Cl 13 of 14 summarise the reactions of the hydrogen halides with H2SO4 HF/HCl dont react. HBr reduces to SO2. HI reduces to H2S 14 of 14
