Question

he chemical method of analysis in determination of the blood alcohol content (%BAC) is: K2Cr2O7 + H2SO4 + C2H5OH → Cr2(SO4)3 + K2SO4 + CH3COOH + H2O What are the stoichiometric coefficients for the reaction above? (please enter the coefficients without spaces and with a coma between the numbers, e.g. 1,2,3,4)

Answer 1

Explanation:

Stoichiometric coefficients : these are the numeral which written before the chemical symbol of the chemical substance in a balanced chemical reaction.

We are given with the chemical equation which is used in blood alcohol content.The balanced chemical equation will be given as:

$2K_2Cr_2O_7 + 8H_2SO_4 + 3C_2H_5OH\rightarrow 2Cr_2(SO_4)_3 + 2K_2SO-4 + 3CH_3COOH + 11H_2O$

The stoichiometric coefficient of potassium dichromate = 2

The stoichiometric coefficient of sulfuric acid= 8

The stoichiometric coefficient of ethanol= 3

The stoichiometric coefficient of potassium sulfate = 2

The stoichiometric coefficient of chromium(III) sulfate = 2

The stoichiometric coefficient of acetic acid = 3

The stoichiometric coefficient of water = 11
