Question

Multiple choice:

Chemical equations provide:

a...the physical state of each reactant and product

b...the ratios of reactants and products

c...the chemical identity of the reactants and products

d...All of these are correct.

Answer

Option d (All of these are correct) is correct.

All options are correct because in chemical equation:

the chemical identity of the reactants and products is expressed by their chemical formulas,

the ratios of reactants and products are expressed by stoichiometric coefficients (numbers before chemical formulas of reactants and products)

and physical state of each reactant and product is usually specified by latter in brackets (s, l, g or aq) after each chemical formula in the equation.

Sometimes, however, physical state is not specified in chemical equations, in such case options b and c are correct.
