balanced chemical equations follow the law of conservation of mass and charges. the masses and charges on either sides of the equation should be balanced.in conservation of mass, the number of atoms of each element on left side should be equal to the number of atoms of each element on the right side of the equation.1)k₂so₄ + 2ca(no₃)₂ --> 2kno₃ + 2caso₄number of ions left side right side k⁺ 2 2so₄²⁻ 1 2ca²⁺ 2 2no₃⁻ 4 2in this equation the masses of so₄²⁻ and no₃ are not balanced. therefore this equation violates the law of conservation of mass2)ti + 2 cl₂ > ticl₄ left side right side ti 1 1cl 4 4this equation follows the law of conservation of mass3)2c₂h₂ + 5o₂ > 4co₂ + 2h₂o left side right side c 4 4h 4 4o 10 10this equation follows the law of conservation of mass4)baso₄ + 2naoh --> ba(oh)₂ + na₂so₄ left side right side ba 1 1so₄²⁻ 1 1na 2 2 oh⁻ 2 2this equation follows the law of conservation of massanswer is 1st equation

1. suppose a reaction mixture, when diluted with water, afforded 300 ml of an aqueous solution of 30 g of the reaction product malononitrile [ch2(cn)2], which is to be isolated by extraction with ether. the solubility of malononitrile in ether at room temperature is 20.0 g/100 ml, and in water is 13.3 g/100 ml. what weight of malononitrile would be recovered by extraction with (a) three 100-ml portions of ether and (b) one 300-ml portion of ether? suggestion: for each extraction, let x equal the weight extracted into the ether layer. in part (a), the concentration in the ether layer is x/100 and in the water layer is (30 x)/300; the ratio of these quantities is equal to k 20/13.3.
