Question:

How do you solve this problem?

A load of bricks is being lifted by a crane at a velocity of 5 m/s when one brick falls off 6m above the groundWhat is the greatest height the brick reaches above the ground?How do you solve it?

Answer:

Fe is oxidizing agent and reduce in reaction Fe3+ - Fe and accept 3 electrons Al is reducing agent and oxide in reaction Al - Al3+ and lose 3 electrons an 6 electrons are transfered in this balance reaction 2Fe3+ + 6e - 2Fe 2Al - 2Al3+ + 6e
The oxidizing agent is the compound that is reduced in the reactionSince Fe2O3 is being converted to Fe(l), a reduction, Fe2O3 is the oxidizing agentLikewise, Al is being oxidized, so it is the reducing agentEach Fe3+ is gaining 3 electrons, and since you have 2 Fe3+, you are transferring 6 electrons.
By v^2 u^2 - 2gh 0 (5)^2 - 2 x 9.8 x h h 1.28 m H h + 6 H 7.28 m
