Here is one way to produce methanol: CO + 2 H2→ CH3OH . This reaction has a △H rxn= -128 kJ. How much heat (in kJ) is released when you completely react 4.04 g CO?
A.-517 kJ
B.-128 kJ
C.-14,500 kJ
D.-18.5 kJ
E.none of the above
If I take a 4.72 gram sample of cesium and react it with oxygen to
form 5.86 gram of the metal oxide, what is the formula of the oxide? You must show all work to receive credit.

`Oxidation-reduction reactions are also known as redox reactions. We learned about their unique characteristics in this lesson. Which of the following would be a FALSE statement given what we learned about redox reactions?
A.if an atom gains 1 or more electrons, it is “reduced”
B.when a redox reaction occurs, either reduction happens or oxidation happens, but never both in the same reaction
C.Redox reactions often involve elemental oxygen
D.If an atom loses 1 or more electrons, it is “oxidized”
E.All of the above statement are true.
Assume you take a sample of 11.4 g Al and oxidize it (in an excess stream of O22323223
) to produce 2.10 g of AlO. Calculate the percent yield of AlO. Reaction: 4 Al + 3 O → 2 AlO.
