Consider this reaction: Fe2O3(s) + 3H2(9) = 2Fe(s) + 3H20(9)
=98.7kJ
AH
If this system was in a closed container at
equilibrium, and a small about of hydrogen gas
was injected into the container, how would the
reaction respond? Or which direction would the
reaction "shift" towards?
Options:
1)making more reactants
2)making more products

Consider a culture medium on which only gram-positive organisms such as staphylococcus aureus colonies can grow due to an elevated nacl level. a yellow halo surrounds the growth, indicating the bacterium fermented a sugar in the medium, decreasing the ph as a result and changing the color of a ph indicator chemical. this type of medium would be referred to as a differential and enrichment culture.
