Which is NOT true with the following reactants after a double replacement reaction? BaCl2 + CuSO4 ->n
a. BaSO4 and CuCl2 are created.

b. Barium is the more reactive metal.

c. Barium sulfate and Copper Chloride are created.

d. One of the products name is Copper I chloride.

Answer : d) One of the products name is Copper I chloride.

Explanation : The products are Barium Sulphate and Copper (II) Chloride.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
