State the order of reactivity of the three metals, giving a reason for your answer.
increasing reactivity: Z, X, Y - X displaces Z so X is more reactive than Z; X does not display Y so Y is more reactive than X
Plants absorb mineral ions through their roots. What is this?
phytoextraction or phytomining
What happens at the highlighted point?
equilibrium (when it levels off)
How does equilibrium shift if nitrogen dioxide is added to this reaction? (justify your answer)
shift to products (right) to compensate for the stress on reactants
How does equilibrium shift if nitrogen dioxide is removed from this reaction? (justify your answer)
shift to reactants (left) to compensate for the lack of stress on reactants
