Enter either the number of moles or weight for one of the compounds to compute the rest. In a decomposition reaction, one product is broken down into smaller species on the product side. It is also a strong oxidizing agent, as it contains a chlorine atom at the valence I (redox state: Cl+1). The problem comes with the expected yield of Hydrogen gas. Calcium hypochlorite is strongly basic. We calculated the expected yield to be 336 mL H2 at STP if 5.00 mL HCl is used. Remember that the density of aqueous solutions is MUCH higher than the density of gases. Ca + HCl → CaCl 2 + H 2. if i'm right, percentage yield should be: (how much came out)/(how much you put in) so in this case mass of CaCl divided by total mass of HCl and Ca. The forward, backward, and weak sideway scatterings are found in the Ca + HCl → CaCl + H molecular reaction. Calcium hypochlorite is stored dry and cold, away from any acid, organic materials, and metals. CaCO3 + 2 HCl = CaCl2 + H2CO3. If you used pure calcium then not all of the reaction would've gone as planned as the HCl is aqueous. In the laboratory, $20.0$ milliliters of an aqueous solution of calcium hydroxide, $\ce{Ca(OH)2}$, was used in a titration. But the question states that the actual yield is only 37.91 g of sodium sulfate. There will be no reaction.
