Here is a chemical symbol reaction.
HCl(aq) + NaOH)aq) = H2O(l) + Na^+(aq) + Cl^-(aq)
This describes the reaction between hydrochloric acid (HCl) and sodium hydroxide(NaOH). The reaction produces water(H2O) and sodium cations and chloride anions.
The '(aq)' means aqueous, in other words the substances/ions are dissolved in water. The '(l)' means that the water is in a liquid state, neither ice nor steam.
Other symbols are '(s)' solid, and '(g)' gas.
Also that the reaction is balanced chemically, you have NOT 'magiced' up extra atoms
Another reaction is the thermal decomposition of calcium carbonate.
CaCO3(s) ==heat==> CaO(s) + CO2(g)
Notice that the physical agent 'heat' is put in the 'equals' and is not a reactant.
An incorrect chemical reaction is
H2SO4(aq) + NaOH(aq) = NaSO4(aq) + 2H2O(l)
This is because the 'Law of Conservation of Mass' is not observed.
Reason ;
#1 You start of with '5' (4+1)oxygens and end up with '6' (4+2)oxygens. Where has the extra oxygen atom come from ????
#2 Similarly, you start of with '3'(2+1) hydrogens and end up with '4' (2 x 2 = 4)hydrogens. Where has the extra hydrogen atom come from ???
#3 'NaSO4' is the incorrect formula for sodium sulphate. It should be 'Na2SO4'.
The correct reaction equation is
H2SO4(aq) + 2NaOH(aq) = 2H2O(l) + 2Na^+(aq) + SO4^2-(aq) ; [Na2SO4]
You will find that all the atoms of the elements balance.
So please make sure you balance all your chemical reactions. !!!!

Yes, the signs of a chemical reaction are: gas, precipitation, heat, color change
What is a chemical reaction Hint Think of the table with signs of a chemical reaction?
The question does not have the enough required information that is required to accurately answer it.
Why do chemists sometimes include special symbols in chemical equations?
Chemists use special symbols like arrows, plus signs, and various abbreviations to represent the different chemical reactions and processes happening in a reaction. These symbols help to convey important information about the reactants, products, and conditions of the reaction in a concise and standardized way. They make it easier for chemists to communicate and understand the reactions being depicted.

How could you visually tell that something is having a chemical reaction?
If you see fizzing, bubbling, or a change in color. They're good signs of chemical reactions you can see. Also, smoke. If you see smoke, you probably have a chemical reaction.
In which situation is a chemical reaction occurring?
A chemical reaction occurs when there is a change in the chemical composition of substances involved, resulting in the formation of new substances with different properties. Signs of a chemical reaction include the release of heat or light, formation of a precipitate, color change, or production of gas.
