What is the number you place to the left of the formula for a substance taking part in a reaction?

Answer 1

You may refer to the #"stoichiometric coefficient........."#

We can analyze the coefficient by referring to a typical combustion reaction, such as the one involving ethane (i) or methane (ii), as demonstrated.

#CH_4(g) + O_2(g) rarr CO_2(g) + 2H_2O(g)# #(i)#

#H_3C-CH_3(g) + 7/2O_2(g) rarr 2CO_2(g) + 3H_2O(g)# #(ii)#

For #(i)# the stoichiometric coefficients are #"1, 1, 1, and 2"#.

And for #(ii)# the stoichiometric coefficients are #"1, " 7/2, " 2, and 3"#.

In relation to molar quantities, these coefficients here indicate the stoichiometric proportions of reactants and products.

Every chemical reaction ought to be balanced stoichiometrically in terms of both charge and mass.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
