Potassium chlorate decomposes upon slight heating in the presence of a catalyst, according to the reaction below. 2 KClO 3 ( s) → 2 KCl ( s) + 3 O 2 ( g) In a certain experiment, 40.0 g KClO 3 is heated until it completely decomposes.
WebNow that we have the balanced equation, let's get to problem solving. To review, we want to find the mass of N a O H \ce{NaOH} N a O H N, a, O, H that is needed to completely react 3.10 3.10 3. 1 0 3, point, 10 grams of H X 2 S O X 4 \ce{H2SO4} H X 2 S O X 4 . We can tackle this stoichiometry problem using the following steps: WebThe explanation for this is illustrated in Figure 9.5.1. According to Avogadro’s law, equal volumes of gaseous N2 N 2, H2 H 2, and NH3 NH 3, at the same temperature and pressure, contain the same number of molecules. Because one molecule of N2 N 2 reacts with three molecules of H2 H 2 to produce two molecules of NH3 NH 3, the volume of H2 H 2 ...
