What is the name for Sn(NO3)4

Tin (IV) Nitrate

General Formulas and Concepts:

Chem

Explanation:

Sn has 2 general forms in charges: Sn²⁺ and Sn⁴⁺ as it is a Post-Transition metal.

Nitrate, NO₃⁻, has a 1 minus charge.

To balance out these charges from the given compound, we know that there are going to be 4 nitrates to balance out a charge. +4 and -4 equals 0, so the charge of Sn would be +4.

Therefore, our compound name would be Metal (Oxidation Number) polyatomic ion:

Tin (IV) Nitrate

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
