b) Propanol (I): \( \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{OH} \). c) Acido 2,3 -dihidroxibutanodioico (s): COOH CHOH CHOH COOH . d) Carbonato cálcico (s): \( \mathrm{CaCO}_{3} \). 17. La descomposición térmica del clorato potásico \( \left(\mathrm{KClO}_{3}\right. \) ) origina cloruro de potasio ( KCl ) y oxigeno molecular. Calcula el calor que se desprende cuando se obtienen 150 litros de oxigeno medidos a \( 25^{\circ} \mathrm{C} \) y 1 atm de presión.

Which of the following is an example of anionic interference in atomic emission spectroscopy? O Interference of high concentration of sodium ions in assay calcium ions. Interference by formation of less volatile salt with sulphat by calcium. Decreased drop size of the analyte solution by alcohols.
