1. If 2 moles fH_(2)O react completely with Na, how many moles of NaOH are produced? A. 1 mole B. 2 moles C. 3 moles D. 4 moles

The balanced chemical equation for the reaction between water (H₂O) and sodium (Na) is:<br /><br />\[ 2Na + 2H_2O \rightarrow 2NaOH + H_2 \]<br /><br />From the equation, we can see that 2 moles of NaOH are produced for every 2 moles of H₂O that react with 2 moles of Na. Therefore, if 2 moles of H₂O react completely with Na, 2 moles of NaOH are produced.<br /><br />So, the correct answer is:<br />B. 2 moles
