Calculate: select the worksheet tab. this tab you calculate the analyte concentration. fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.) record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes. record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed

Consider the reaction: 2al(s) + fe2o3(s) → al2o3(s) + 2fe(s) the δhf for fe2o3(s) = -824.3 kj/mole. the δhf for al2o3(s) = -1675.7 kj/mole. finish the equation. δhrxn = [(1)( kj/mole) + (2)( kj/mole)] - [(1)( kj/mole) + (2) ( kj/mole)]
