Bi, atomic weight 208.989 amu .
Express your answer using six significant
figures.

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3

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)]

What conclusion can you draw from this experiment about the components of the black ink?
