In an experiment, 170.9 g of C2H4 was reacted with an excess of O2, 164.1 g of CO2 is produced.

C2H4 (g) + 3 O2(g) → 2 CO2 (g) + 2 H2O (l)

What is the percent yield of this reaction?

Read these sentences from the text. near the equator, the tropics receive the most rain on a consistent basis. as a result, the fresh water falling into the ocean decrease the salinity of the surface water in that region. [. .] . . as the salt content of sea water increases, so does its density. what can you infer about how rain affects the density of surface water near the equator?

Drag each label to the correct location on the chart. classify each reaction as endothermic or exothermic.
