The meaning of (s) is solid.
The new substance(s) formed during a chemical reaction will appear to the right of the "yield" arrow in an equation. This/these is/are the product(s) of the reaction.
Writing a chemical reaction with symbols: Ex.: NaCl + AgNO3 = AgCl (s) + NaNO3 A mathematical (digital) system for the writing of chemical equations exist but it is rarely used.
the chemical equation of aluminium and iodine is given a s follows :2Al +3 I -> Al 2 I 3.This is a balance eqaution .
2Al(s) + 6OH-(aq) - 6e- Al2O3(s) + 3H2O(l)
This reaction is: Fe(s) + CuSO4(aq)----- --> FeSO4(aq) + Cu(s)
The balanced chemical equation when rust occurs is given as.2Fe(s) + 2H2O(l) + O2(g) 2Fe2+(aq) + 4OH-(aq)Fe2+(aq) + 2OH-(aq) Fe(OH)2(s)Fe(OH)2(s) =O2=> Fe(OH)3(s)Fe(OH)3(s) =dehydrates=> Fe2O3.nH2O(s) or rustThe chemical formula for rust is Fe2O3.nH2O.The overall chemical equation for the formation of rust isIron + water + oxygen rust
2Fe(s) + 2H2O(l) + O2(g) ==> 2Fe2+(aq) + 4OH-(aq)---------------------------------------Iron rust is hydrated Fe2O3 and Fe(OH).Fe(OH)3.4Fe + 3O2 = 2Fe2O3.
S is the chemical symbol of sulfur.
2Fe(s) + 2H2O(l) + O2(g) ==> 2Fe2+(aq) + 4OH-(aq) This is the equation for rust. ---- NOT EXACTLY Rust is a solid, it doesn't exist as ions in solution. Also, in rust, iron is in the +3 oxidation state. There are three common forms of rust. Rust formed under water is Fe(OH)3. Rust formed in humid air is FeO(OH). Only when rust has completely dehydrated will you see it as Fe2O3. The reaction for the rust that we see around us most often is: 4Fe(s) + 3O2(g) + 2H2O(l) --> 4FeO(OH)(s) FeO(OH) is also formed naturally, and is the mineral called goethite.
I think it`s a chemical change.
B(s)
Br- is chemical symbol for a bromide anion. It is not an 'equation', it can be a part of a chemical equation, like in this precipitation reaction (example) Ag+(aq) + Br-(aq) --> AgBr(s) .
The new substance(s) formed during a chemical reaction will appear to the right of the "yield" arrow in an equation. This/these is/are the product(s) of the reaction.
4Fe(s) + 3O2(g) --> 2Fe2O3(s)
Writing a chemical reaction with symbols: Ex.: NaCl + AgNO3 = AgCl (s) + NaNO3 A mathematical (digital) system for the writing of chemical equations exist but it is rarely used.
The chemical equation is:2 Al + 3 S = Al2S3
The chemical equation is:Mg+ + 2 OH- = Mg(OH)2(s)
