Question

If an aqueous solution of is added to a mixture of Pb^2+ and ba^2+, the lead ion will precipitate. but the barium ion will remain in solution. NaOH Na_2SO_4 K_3PO_4 KCO_3 Ca(CH_3CO_2)_2 Which one of the following equations is properly balanced? Sn + 4HNO_3 rightarrow SnO_2 + 4NO_2 + 2H_2O 2Na_2S0_4 + 3Bi(NO_3)_3 rightarrow Bi_2(S0_4)_3 + 9NaNO_3 CH_3CHO + 3O_2 rightarrow 2CO_2 + 2H_2O NH_4NO_3 rightarrow 2H_2O+N_2 Na_2CO_3 + 2H_2SO_4 rightarrow Na_2S0_4 + 2H_2O + CO_2 All of the following compounds are soluble in water except. RuCO_3 K_2CO_3 (NH_4)_2CO_3 CS_2CO_3 Li_2CO_3

Explanation / Answer

10) Option E

because Ba(CH3CO2)2 is not precipitated.

11) Option A as it is exactly balanced as there are same no of atoms of products and reactants side

12) Li2CO3 is insoluble in water.

Option e
