Explanation:
It is being aware of things around you and the decisions you make. Being in control of your own actions.
An ionic compound is composed of anions and cations. A cation is a positively charged ion, and an anion is the opposite. A metal is composed of two or more cations. Since you need at least one cation and one anion for an ionic compound, the metal is not ionic.
The enthalpies of formation of each of the compound involved in the chemical reaction presented above are given below:
CO2: -393.5 kJ/mol
CO: -99 kJ/mol
O2: 0 kJ/mol
As observed O2 will not have enthalpy of formation as it is a pure substance.
To calculate for the enthalpy of reaction,
enthalpy of formation of products - enthalpy of formation of reactants
= (-99 kJ/mol) - (-393.5 kJ/mol)
= 294.5 kJ/mol
ANSWER: 294.5 kJ/mol
