A) advantages: you see all the molecules added in the reaction mixtures, can calculate stoichiometry, useful in equillibrium constant, enthalpy, etc. calculations
disadvantages: it can get complicated to balance (i.e. redox reactions)
B) advantages: you can see all ions participating and spectator ions, easier to balance
disadvantages: not all ions participate ion reactions, so they just make things look complicated
C) advantages: only reacting species, so it has all the information needed about the reaction itself in the simplest way
disadvantages: can't really calculate all those mentioned in point A
Nothing, you must realize that almost everything is an equation.
What to eat today? x = what to eat
That's a bad example, but you see my point.
Equations are simply a line with an equal sign.
3x + 5 = y etc. In solving any problem with an unknown using known, we must establish a relationship, and we NEED equations (or inequalities)
Unlike solutions, mixtures, and alloys, and like tattoos, most chemical reactions are not easily reversed. Unpredictable and uncontrolled results, such as some violently exothermic reactions, can be dangerous. Products can be hazardous to human health. Chemical reactions can produce bombs but can also give us medicines.
They usually don't show the conditions (i.e. pressure, temperature) at which said reactions occur or whether they can occur. A lot of textbooks will have the student balance chemical equations as an academic exercise without considering whether such a reaction can (is likely) to occur.
For example:
2H2 + O2 -> 2H2O, but it takes combustion via spark/flame to actually initiate the reaction.
P.S. Sometimes the conditions are indicated over the reaction arrow.
it makes our surroundings smell bad......And it also poison us

The overwhelming majority of chemical equations do involve molecules, but if they don't, you can call them chemical equations rather than molecular equations.
formulas
A chemical formula describe and identify a chemical compound.

Well chemical equations can help us understand how a certain substance is made and what combines with what to make it using symbol and word equations .It makes more understanding of the concepts through symbols.
Honey hasn't chemical equations.
Chemical equations describe the products and reactants in a chemical reaction.
Chemical equations represent chemical composition of reactants and products and also how does the reaction occur.
The overwhelming majority of chemical equations do involve molecules, but if they don't, you can call them chemical equations rather than molecular equations.
chemical equations
Any chemical equations violates the law of conservation of energy.
Chemical equations provide the formulas of reactants and products in a chemical reaction. They usually do not provide structure unless supplemented with chemical structures.
Chemical reactions are abbreviated by their chemical equations.
Chemical equations are representative for chemical reactions.
its easier
Yes, chemical equations must be balanced due to the law of conservation of matter/mass.
This is chemistry, especially chemical kinetics.
