compound flencer
We use the term 'symbol' to refer to the shorthand for individual elements. Compounds have a formula made up of the symbols for the component elements with their relative numbers. For potassium oxide this is K2O.
The ionic compound of K2O is potassium oxide. It is formed from the combination of potassium (K) cations and oxide (O) anions. Its chemical formula is K2O.
K2O is potassium oxide
The balanced equation is 2HCl + K2O -> H2O + 2KCl.
The oxidation number for O in K2O is -2. Oxygen typically has an oxidation number of -2 in most compounds. Since there are two oxygen atoms in K2O, the total oxidation number contributed by the oxygen atoms is -4.

the numbers on the fertilizer are the percent content of the following (in order): N2, P2O5, K2O
The ionic compound of K2O is potassium oxide. It is formed from the combination of potassium (K) cations and oxide (O) anions. Its chemical formula is K2O.
K2O is potassium oxide, which is an ionic compound.
K2O is potassium oxide
We know that K2O is the chemical formula for potassium oxide.
The balanced equation is 2HCl + K2O -> H2O + 2KCl.
Three potassium oxides are known: K2O, KO2, K2O2.
According to the reaction (4 \text{K} + \text{O}_2 \rightarrow 2 \text{K}_2\text{O}), 4 moles of potassium produce 2 moles of potassium oxide (K2O). Thus, the mole ratio of potassium to K2O is 4:2, or 2:1. If 1.52 moles of potassium are used, the number of moles of K2O formed can be calculated as (1.52 , \text{moles K} \times \frac{2 , \text{moles K2O}}{4 , \text{moles K}} = 0.76 , \text{moles K2O}). Therefore, 0.76 moles of potassium oxide will be formed.
The oxidation number for O in K2O is -2. Oxygen typically has an oxidation number of -2 in most compounds. Since there are two oxygen atoms in K2O, the total oxidation number contributed by the oxygen atoms is -4.
