To produce 2 moles of H2O how many moles of HCl need to be consumed in the following reaction? 6HCl+Fe_(2)O_(3)arrow 2FeCl_(3)+3H_(2)O A. 0.5 mol B. 1.0 mol C. 2.0 mol D. 4.0 mol A B c D

To determine how many moles of HCl are needed to produce 2 moles of H2O, we need to use the stoichiometric coefficients from the balanced chemical equation.<br /><br />The balanced chemical equation is:<br />6HCl + Fe2O3 → 2FeCl3 + 3H2O<br /><br />From the equation, we can see that 6 moles of HCl are required to produce 3 moles of H2O.<br /><br />To find the number of moles of HCl needed to produce 2 moles of H2O, we can set up a proportion:<br /><br />6 moles of HCl / 3 moles of H2O = x moles of HCl / 2 moles of H2O<br /><br />Solving for x, we get:<br /><br />x = (6 moles of HCl / 3 moles of H2O) * 2 moles of H2O<br />x = 4 moles of HCl<br /><br />Therefore, the correct answer is D. 4.0 mol.
