Color: Undesignated: Quantity: 500mL: Chemical Name or Material: Hydrochloric acid . Answer (1 of 2): H2 + Cl2 =2HCl, hence they react in a 1:1 molar ratio H2 molar wt: 2g Cl2 molar wt: 71g So, 10 g of H2=10/2=5 moles of H2 and, 20g of Cl2= 20/71= 0.28 moles of Cl2 Clearly, Cl2 has lesser no. Calculate the mass of iron (in grams) that can be formed from this mixture of reactants. Fe—HCl: An Efficient Reagent for Deprotection of Oximes as well as Selective Oxidative Hydrolysis of Nitroalkenes and Nitroalkanes to Ketones. Using the three reagents: NaOH, NH 3, and HCl Before you can develop a flow scheme for analyzing an unknown, you need to know how each of the four ions to be tested (Al3+, Fe , Ni2+, and Pb2+) will react with each of the three reagents to be used (6 M HCl, 6 M NH 3, and 6 M NaOH). 1)The correct and balanced equation is, Fe(OH)2+ 2 HCl=FeCl2+2 H2O In the L.H.S of the equationFe(OH)2affords 1 Fe,2 O & 2 H atoms.2 HCl afffords 2 H, 2 Cl atoms.
