Equations can be balanced by using the half-reaction method. Which step should be completed first when using this method?
inserting the coefficients
balancing the half reactions
identifying the half reactions
finding the oxidation states of atoms
O

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon
