in a chemical equation, how do i know what symbol to put after an element? like (aq), (l), (s), etc? is there a certain way? coz i'm so confused

how do i know which elements are gas, liquid, solid, or under aqueous solution?

There are 2 elements that are liquid at room temp, mercury Hg and bromine Br. The gases are hydrogen H, helium He , oxygen O, nitrogen N, chlorine Cl,fluorine F, and all of the inert gases.there are a couple metals that melt in your hand like cesium. However this info doesn't really help you because it has no bearing on the state of the compounds.
You do not need to put the state of all the materials in an equation. The importantt ones are if a precipitate is formed(solid)
or if a gas is formed in a reaction.
Many reactions take place in water as solids do not tend to react with each other easily. aqueous

It depends what the state of the material is. If it's a solid, then put a (s) after. If it's dissolved in solution, put a (aq) after. The vast majority of what you'll be working with are solids and aqueous materials, with the exception of liquid for water.

Those abbreviations just indicate the state of matter the reagents and products are in. g for gas, l for liquid, s for solid, and aq for aqueous solution. If you have that information, then you can easily determine which symbol to use.

in case you're making use of MS be conscious: a million. decide for Insert…Symbols to function symbols that are actually not accessible on your archives (e.g. PI) 2. For including complicated symbols (e.g. integration, summation, and so on.) use Insert…merchandise from the menu. From the displayed communication, decide for "Microsoft Equation". collectively as in this show, test or you will omit a great style of stuff.

You only can know by learning from a teacher or a book. After putting effort on chemistry for say 1 year, you will have experience to make your own assumptions, but you are never sure if there isn't a surprise,done by chemistry to you.

if it is soluble in water it's aq
if it's a pure liquid (ex. H2O) it's l
if it's a ppt it's s
