Oxygen gas is formed by the decomposition of potassium chlorate at high temperatures according to thereaction 2 KC10, (s) → 2 KC1(s)+3 0,(g). Suppose 1.23 g KCIO; is placed in a container connected toan open-end mercury manometer on a day when atmospheric pressure is 1.00 atm. Once the reaction iscomplete, the height of the mercury column in the U-tube on the side of the reaction container rises by172 mmHg. What is the pressure of O2 gas produced by the reaction?1348 torr22.9 kPad. 0.774 atma.36.7 in Hgb.0.559 bare.c.

As the height of the mercury column is rising on the side of the reaction, the expression for the…
