How are chemical formulae of different compounds represented?
Is that all you want? We could be here for days!
Chemical formulae represent the combinations of atoms to give molecules and compounds of different elements, e.g.
And chemical equations are a simple shorthand means to represent how elements and compounds chemically interact to form new compounds and materials. A typical chemical reaction is the combustion of methane gas with dioxygen, the which underlies our industrial civilization:
Using the known masses of (given quantities) of elements we can thus use the given equation to represent mass and energy transfer: i.e.
All known chemical reactions CONSERVE mass and CONSERVE energy. What does this mean in the given context?
