CHEMISTRY PART TEST - 1 1.The brown tintinnabulation conglomerate compound is formulated as [Fe(H2O)5(NO)]SO4. The oxidation produce of straighten out is: (A)1(B)2 (C)3(D)0 2.The equivalent free weight of MnSO4 is half its rampartcular(a) weight when it is converted to: (A)Mn2O3(B)MnO2 (C)MnO4(D)MnO42 3.A example of tap pissing contains 366 ppm of HCO3( ions with Ca+2 ion. Now it is removed by Clarks regularity by addition of Ca(OH)2. Then what minimum mound of Ca(OH)2 lead be required to remove HCO3- ions whole from viosterol g of same tap water sample (A) 1 g(B)0.4g (C) 0.222 g (D) 0.111 g 4.55 g Ba(MnO4)2 sample containing inert impurity is completely reacting with 100 mL of 56 vol skill of H2O2, then(prenominal) what will be the section purity of Ba(MnO4)2 in the sample ? (Ba 137, Mn 55) (A) 40%(B)25% (C) 10%(D) 68.18% 5.An aqueous firmness of purpose of 0.57 g of KIO3 (formula weight = 214) reacts with excess of KI in carriage of HCl, where both converts into I2. The liberated I2 consumes certain volume of (0.1 M) Na2S2O3, in staple fiber intermediate where it converts into SO42-, then find out the volume of Na2S2O3 (in mL) unavoidable to egest the equivalence point. (A) 19.97(B)29.97 (C) 24(D) 35 6. The labeling on a store of H2O2 declaration is 20 vol, then the concentration of H2O2 in percentage strength will be: (A) 3.03 %(B)5% (C) 4.55%(D) 6.06 % 7.CIF3 (molecular weight, M1) can oxidize UF4 (molecular weight, M2) UF6 and get rock-bottom to Cl2 itself. Equivalent weights of CIF3 and UF4 respectively in this chemical reaction ar (A)M2/2, M1/6(B)M1/3, M2/2 (C)M1/6, M2/2(D)M1/6, M2/6 8.In redox reaction, H2O2 oxidises K4[Fe(CN)6) into K+, Fe+3, CO3-2 and NO3- ions in acidic medium, than how many moles of H2O2 will react with 1 mole o f K4[Fe(CN)6] (A) 5 moles(B)9mol! es (C) 8 moles (D) 30.5 moles Section iI Multiple right(a) Answer...If you wish to get a full essay, order it on our website: OrderCustomPaper.com
