<u>Answer:</u> The balanced molecular equation is written below.

<u>Explanation:</u>

A molecular equation is defined as the chemical equation in which the ionic compounds are written as molecules rather than component ions.

When zinc (II) nitrate reacts with sodium hydroxide, it leads to the formation of white precipitate of zinc (II) hydroxide and an aqueous solution of sodium nitrate.

The balanced chemical equation for the above reaction follows:

$Zn(NO_3)_2(aq.)+2NaOH(aq.)\rightarrow Zn(OH)_2(s)+2NaNO_3(aq.)$

By Stoichiometry of the reaction:

1 mole of aqueous solution of zinc (II) nitrate reacts with 1 mole of aqueous solution of sodium hydroxide to produce 1 mole of solid zinc hydroxide and 2 moles of aqueous solution of sodium nitrate

Hence, the balanced molecular equation is written above.

zysi [14]

The correct answer is condensation

That is because energy is used to break bonds, so condensation where bonds are made actually loses energy because it turns into liquid.

How does the number of valence electrons determine the type and number of bonds an element forms?

Advocard [28]

The number of electrons in an atom's outermost valence shell governs its bonding behaviour. Elements whose atoms have the same number of valence electrons are grouped together in the Periodic Table. ... Nonmetals tend to attract additional valence electrons to form either ionic or covalent bonds.
