A gas has a pressure of 50.0 mm Hg at 247°C. What will be the final temperature, in K, if the pressure changes to 2.53 kPa and the volume does not change? I have been trying to use the formula (V1)P1) / (n1)(T1) = (V2)(P2) / (n2)(T2) but can not get to the answer.

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)]
