A college student ran out of salt and pepper to season his eggs with. All of the stores he went to was out of salt so he took it upon himself to make his own. He used copper (II) chloride and sodium nitrate to produce copper (II) nitrate and sodium chloride. The equation for this reaction is shown: __CuCl2+ __NaNO3__Cu(NO3)2+ __NaCl. Identify the coefficients by balancing theequation and tell what type of reaction it is. a.1, 2, 1, 2; single replacementb.2, 4, 2, 4, decompositionc.1, 2, 1, 2; double replacementd.1, 2, 3, 4; combustion

B

Explanation:

I’m not really great at chemistry but I truly tried my best

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.
