Students are making solutions by dissolving potassium chloride into water. There is 100 mL of water at 60°C in each beaker. The students dissolve different amounts of
potassium chloride in each beaker. The models below each represent the beakers
with water and different amounts of KCL

Which of the following statements about the models is true? (Select Two)
A. The solution in beaker A has the greatest concentration
B. The solution in beaker B has the greatest concentration
C. The solution in beaker C has the greatest concentration
D. The solution in Beaker A has the highest conductivity.
E. The solution in Beaker B has the highest conductivity.
F. The solution in Beaker C has the highest conductivity

They both go downwards and the can break apart rocks 

  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
