The reactants of a chemical equation are 3H2 and Nz. Which set of atoms must make up the equation's products so that the equation models the law of
conservation of mass?
A. 2 H and 2 Na
B. 4 Hg and 3 N
C. 6 H and 2 N
D. 8 H and 2 Na

If you mean N2 and not Nz, it should be C.

Explanation:

B.) 6 H and 2 N

Explanation:

:p

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.
