More than one option may be correct

1: one mole BaF2 + 2mole H4S4 …………….>resulting mixture will be neutralised by:
(a) 1 mole of KOH (b) 2mole of Ca(OH)2
(c)4mole KOH (d) 2mole of KOH
2: when (NH4)2Cr2O7 is heated:
(a)there is oxidation of N (b)there is reduction of Cr
(c)net reaction is disportionation (d) net reaction is neutralization
3: 11.2g of mix of MCl(volatile) & NaClgave 28.7g of white ppt with excess of AgNO3 soln.11.2g of same mix on heating gave a gas that on passing in t o AgNO3soln gave 14.35g of white ppt. hence:
(a)ionic mass of M+ is 18 (b)ionic mix have equal mile fraction of MCl & NaCl.
(c) MCl & NaCl are in molar ratio 1:2 (d) ionic mass of M+ is 10
4: 10.78 g of H3PO4 in 550 ml solution is 0.40N. thus this acid has been:
(a)neutralised to HPO42- (b) neutralised to PO43-
(c)reduced to HPO32- (d) neutralised to H2PO4-
