When thorium-234 undergoes beta decay, what other product is formed?.

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)]

In an exothermic reaction, energy may be released to the surroundings in the form of question 4 options: heat light thermal all of the above
