1. Aluminum and iron oxide react to produce iron along with extreme heat 2Al * Fr2O4—> Al2O3+ 2Fe 45 KG aluminum is reacted with excess iron (III) oxide to produce 51 KG of iron. Calculate the percent yield for this reaction.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

where's the diagram?
