4LaCl+WO2arrow WCl4+2La2O How many moles of La20 do I get from 0.35 mol WO2? 0.175 0.35 0.7 1.4

To determine how many moles of La2O are produced from 0.35 moles of WO2, we need to use the stoichiometric coefficients from the balanced chemical equation.<br /><br />The balanced chemical equation is:<br />$4LaCl + WO2 \rightarrow WCl4 + 2La2O$<br /><br />From the equation, we can see that the stoichiometric coefficient of WO2 is 1, and the stoichiometric coefficient of La2O is 2.<br /><br />Therefore, the ratio of moles of WO2 to moles of La2O is 1:2.<br /><br />Given that we have 0.35 moles of WO2, we can calculate the moles of La2O as follows:<br /><br />Moles of La2O = (0.35 moles of WO2) × (2 moles of La2O / 1 mole of WO2)<br />Moles of La2O = 0.7 moles<br /><br />Therefore, the correct answer is 0.7 moles of La2O.
