Can someone check my answers? to the following 1) The Decomposition of potassium chlorate KCLO3 is used as a source of oxygen in the laboratory. How many moles of KCL3 are needed to produce 15 mol of oxygen. My answer: KCLO3----> KCL+O2 KCLO3----> 2KCL+3O2 15 mol of O* 2 mol Kclo3 per 3 mol= moles of KCLO3 moles of O* moles of KCLO3/ moles of O(15 moles of o*2 moles kclo3)/3 mol O= 10 mol KCLo3 2) when copper metal is added to silver nitrate in a solution silver metal and copper 2 nitrate are produced. mass of silver produced from 100. g of cu 2ag+cu-->cu2+2ag 339.5 g sliver

    3) If 20.5g chlorine is reacted with 20.5 g na wich reactant is excess ow do you know. cl2+2na-->2nacl so cl2=na1;2 cl2 mass 20.5/70.9=0.289 na mass 20.5/23= 0.891 sodium is exess cause there more of it

    Carbon reacts with steam h20 at high temptures to produce hydrogen and carbon monoxide if 2.40 mol carbon are exposed to 3.10 steam identify limiting My work- c+h20--> co+h2 2.4 moles carbon/1=2.4 water is 3.1/1 so carbon is limiting and water is excess
