Li + HNO3 > LiNO3 + H2 how do I balance it? Show work pls

The balanced equation is .

Explanation:

The given reaction equation is as follows.

Number of atoms present on reactant side are as follows.

Number of atoms present on product side are as follows.

To balance this equation, multiply Li by 2 and by 2 on reactant side. Also, multiply by 2 on product side.

Hence, the equation can be rewritten as follows.

Now, number of atoms present on reactant side are as follows.

Number of atoms present on product side are as follows.

As there are same number of atoms on both reactant and product side. Hence, the equation is now balanced.

Thus, we can conclude that the balanced equation is .

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.

b.

the accuracy of the data.
