Now liters at the same temperatu 'e and pressure: square liters of H_(2)+ liters of O_(2)arrow liters of H_(2)O

To solve this problem, we need to use the stoichiometry of the balanced chemical equation for the reaction between hydrogen gas (\(H_2\)) and oxygen gas (\(O_2\)) to form water (\(H_2O\)). The balanced chemical equation is:<br /><br />\[ 2H_2 + O_2 \rightarrow 2H_2O \]<br /><br />This equation tells us that 2 liters of \(H_2\) react with 1 liter of \(O_2\) to produce 2 liters of \(H_2O\), assuming all gases are measured at the same temperature and pressure.<br /><br />Therefore, the blanks can be filled as follows:<br /><br />- \(\square\) liters of \(H_2\): 2 liters<br />- \(\$\) liters of \(O_2\): 1 liter<br />- \(\$\) liters of \(H_2O\): 2 liters<br /><br />So, the complete statement would be:<br /><br />2 liters of \(H_2\) + 1 liter of \(O_2\) → 2 liters of \(H_2O\)
