CHM 113 Study Guide - Sodium Chloride, Sodium Bicarbonate, Chlorate
Document Summary
Investigation 14: how much sodium bicarbonate is in the mixture? . 2 points: read sections 3. 1, 3. 2, and 3. 3 in your textbook. Also read page 136, acid-base reactions with gas. Review sample exercises 3. 3, 3. 5, and 3. 6: potassium chlorate, kclo3, is composed of potassium, chlorine, and oxygen in a ratio of 1:1:3 (atoms of potassium:chlorine:oxygen). 88) in your text and a periodic table for atomic weights, calculate the percent composition of k, cl, and o in potassium chlorate. % o = ______: when kclo3(s) is heated sufficiently it decomposes completely to kcl(s) and o2(g) according to the balanced equation: Based on your answers in question 2, if 10. 0 g of kclo3(s) undergoes decomposition, what mass of solid remains: calcium carbonate, caco3(s), also can decompose according to the following equation.
