Given the balanced equation representing a reaction:
2co(g) + o2(g)< ==> 2co2(g)
what is the mole ratio of co(g) to co2(g) in this reaction?
(1) 1: 1 (3) 2: 1
(2) 1: 2 (4) 3: 2

Rank the four gases (air, exhaled air, gas produced from from decomposition of h2o2, gas from decomposition of nahco3) in order of increasing concentration of co2

2-bromo-2-methylbutane undergoes an e1 elimination reaction in the presence of ethanol. in the next reaction only one of the possible products is represented. although the product shown is not the major product of the reaction, notice that there is more than one way it can be produced. complete the mechanism and draw the missing substances.
