s stands for solid, and g stands for gas. For completeness sake I will include the fact that l stands for liquid. Hence, the symbols refer to which 'state' the chemicals/compounds in a chemical equation are in.
e.g. if you see H2O (g) this means water vapour/steam. if you see H2O (l) this means liquid water. if you see H2O (s) this means solid/frozen water i.e. ice.
4Fe(s) + 3O2(g) --> 2Fe2O3(s)
There are three common state symbols for chemical formulae. The first is (s) which is solid, the second is (g) which is gaseous, and the third is (aq) which denotes aqueous, or in a liquid solution.
4Bi(s) + 3O2(g)----> 2Bi2O3(s)
2MoO2(s) + 6XeF2(g) <==> 2MoF6(g) + 3O2(g) + 6Xe(g)
4Cr(s)+3O2(g)→2Cr2O3(g)
it is a combustion. the word equation would be: sulfur + oxygen → sulfur dioxide the balanced chemical equation: S(s) + O₂(g) → SO₂(g)
4Fe(s) + 3O2(g) --> 2Fe2O3(s)
2Na (s) + O2 (g) ---> 2Na2O (s)
There are three common state symbols for chemical formulae. The first is (s) which is solid, the second is (g) which is gaseous, and the third is (aq) which denotes aqueous, or in a liquid solution.
4Bi(s) + 3O2(g)----> 2Bi2O3(s)
C6H12O6(s) ===> C6H12O6 (g)Sublimation is going from a solid (s) to a gas (g) without going through the liquid phase. The chemical composition of the compound does not change.
2MoO2(s) + 6XeF2(g) <==> 2MoF6(g) + 3O2(g) + 6Xe(g)
4Cr(s)+3O2(g)→2Cr2O3(g)
To indicate that an element is solid, but (s) afterward. For example: C graphite (s) + O2(g) --> CO2 (g)
A meaningless question. Because an equation relates the interaction of TWO or more substances, while this question mentions only ONE (namely Iron).
O2M(s)+C(s) yields M(s)+CO2(g)
The equation is: C6H12O6(s) + 6O2(g) → 6CO2(g) + 6H2O(l) + Energy (as ATP) or Glucose + Oxygen → Carbon dioxide + Water + Energy (as ATP)
