Stoichiometry One of the specific gravity scales is "Brix" (used speicifically for sugar solution). It is defined as Brix = (400/G) - 400 None of these Brix = 145 - (145/G) Brix = 200 (G-1) Brix = (400/G) - 400 None of these Brix = 145 - (145/G) Brix = 200 (G-1) ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry One mole of methane undergoes complete combustion in a stoichiometric amount of air. The reaction proceeds as CH₄ + 2O₂ → CO₂ + 2H₂O. Both the reactants and products are in gas phase.
