The periodic table is useful tool for chemist since we can see what is the atomic and mass number for each atom.
Atomic number is equal to how many protons and electrons in it
Mass number is equal to protons + Neutrons.
The structural components of a triglyceride is a molecule of glycerol and 3 fatty acids because one triglyceride is made up of glycerol that is made up of 3 different fatty acids.

Answer:
d. The gold(III) ion is most easily reduced.
Explanation:
The standard reduction potentials are
Au³⁺ + 3e⁻ ⟶ Au; 1.50 V
Hg²⁺ + 2e⁻ ⟶ Hg; 0.85 V
Zn²⁺ + 2e⁻ ⟶ Zn; -0.76 V
Na⁺ + e⁻ ⟶ Na; -2.71 V
A <em>more positive voltage</em> means that there is a <em>stronger driving force</em> for the reaction.
Thus, Au³⁺ is the best acceptor of electrons.
Reduction Is Gain of electrons and, Au³⁺ is gaining electrons, so
Au³⁺ is most easily reduced.
