Answer 1

o The awen chemical Maapoy & Nicla reaction is valroul2 + Noel his Seactienis en exchange taceton in which ionic compound having see which ion are enchanged. und having schon in Nazroy - Nich Nat & pouz Mit 2 et Four seaction Mat Nal al nach vi NI (Pouz Noticed we have a phosphate at R s So Fas put two on fsiont of Napoy and three trickel at Rotis so has put three ca front of Nicz, then calculate total sedilim and clomine che n.H.S thate are total sim sodulter and cianine autom potesent on this so has cut sire on isont of Notl, Then the balanced chemical reaction is & NA Pou + 3 Nice The of coefficient 11N13(04) 34 Nich - Mirrohz +Grac! salaried chemical sican 3+1NO,704 : G Naci

H₂O The given chemical reaction is I CHCOH + H₂SO3 - cup (S03)3 + This reaction is ion exchange reaction which ionic compound having scaction in which ion are enchanged. in CH(OH) H₂ 503 - - wit + 304- Sol + RH Fay eaction. comt3 so L- I CM (503)3 & cute (503) HO Noticed we hour three sulphite at RoHS so has put three on front of HQS03 and two Colominum at Roths so has put two on front of CCOH) then to calculate total Hydrogen and anygen on Lotos, there are twelve hydrogen atom and sinonygen atom present on tos sa has put sir on front of sto because one molecules of M20 contoun to hydroge0 -om and one onygen atom, Then the balanced chemical reaction is RCH(OH)3 + 3 H2S03 - 0 S03) 611-0 The coefficient of balanced chemich Men CM₂ (503) 2 CHLOH)3 34 HSO3 a 6 - HU

The given chemical Meaction is KNoz t cas - Ca(NO3)2 + kps & in in The reaction is ion enchange reaction which ionic compound having seaction which ion are exchanged. KNO3k + + Noz cat? & S-2 cas - Fay yeaction kt s-2 Cat2 Noz kps & k₂ si ca, (NO) Ca(NO₃)2 chiced we have two nitiate at RH 5 SO has put two on front of KNO3 and two potassium at R.His previous we have put two. on front KNO3 so potassium is balanced on both side, there are one calcium and one suphay at R.His so has put one on front of cas so both calcium and sulphuy is balanced on both side Then the balanced chemical reaction is 2 KNO3 + cas Ca(NO₃)2 + kos The coefficient of balanced chemical mean y cas c a(NO3)₂ → kas 24 KNO3

e gwen chemical reaction is "S seaction is combustion Heactron Cembution reaction is a major class chemical reaction, commonly re al reaction, commonly referred to an burning combustion, usually occur when a hydrocarbon react with chygen to produce cauthen dioride (co2) and watey (H2O). Noticed we have seven carbon at L.H.S so has put seven en front of coz and sinteen I hydrogen atom at L.H.S so put cight on furont of Hac because I molecules of H₂O centou two hydrogen atom, then calculate onygen atom at R.His there are total twenty two ontgen atom at RoHS so has Put Eleven on front of because I melecure of of contain two anygen atom. A Then balanced chemical reaction is CHIC +1102 7CO2 + 8H30 The coefficient of balanced chemical rean C7H16 7 → coz 8 H₂O 11+02
