You use the criss cross method to swith the charge of the element with the charge of the whole ion
If the charge of the element is more than one then put the ion in parenthesis and then put the charge outside
The chemical symbol for nitrogen is N and it used so that compounds can be given a chemical formula such as NH3 and can be represented in chemical equations for the ease of identifying what elements are in what compounds.
Oxygen is always given the symbol O In chemical compounds there can be many oxygen atoms. The compound has the formula not oxygen. Example Water is the compound, its formula is H2O Sodium sulfate is the compound, its formula is H2SO4
The elements and compounds to the right of the equations are called products.
Yes, metallic bonds are polyatomic, in the sense that all the atoms in a given piece of metal share a bond, it's not just a bond between adjacent atoms, as in other types of bonding such as ionic or covalent.
Symbols are given to elements. Formulas describe compounds. Petroleum contains up to 3,000 different compounds, many in very small quantities. Further, every field has a unique mixture of compounds, so no one formula would work. See link.

Yes, formulas are given to us to help solve problems. It is legal to use them and copyright them
Oxygen is always given the symbol O In chemical compounds there can be many oxygen atoms. The compound has the formula not oxygen. Example Water is the compound, its formula is H2O Sodium sulfate is the compound, its formula is H2SO4
The elements and compounds to the right of the equations are called products.
In addition to common names, compounds can be identified by their chemical formulas, which represent the elements present and their ratios in the compound. Compounds also have systematic names based on IUPAC rules to provide a clear and unambiguous way to refer to them. Additionally, compounds have specific properties, such as melting point, boiling point, and reactivity, that can help to identify them.

Dalton pictured compounds as collections of atoms. For example, nitrogen and oxygen might form a compound containing one atom of nitrogen and one atom of oxygen (written NO), a compound containing two atoms of nitrogen and one atom of oxygen (written N2O), or a compound containing one atom of nitrogen and two atoms of oxygen (written NO2)
Chemical formulas are constructed from elements contained in a given substance. First the composition must be determined by chemical analysis.
An alcohol is the name given to organic compounds containing an -OH group.
yes heat is given of due to the exothermic process in some cases. e.g when caco3 is mixed with water heat is given of.
Because unlike the empirical formula, the molecular formula does not have to be the simplest ratio.If by chance you are given the percent composition of the elements in a substance, you could calculate the empirical formula and then the empirical formula's mass. However, the molecular formula equation is molecular formula= (empirical formula)n, where n is the mass of the molecular formula divided by the mass of the empirical formula. You would, therefore, need to know the mass belonging to the molecular formula, which you are not given.
