Suppose you heat some mercury(ll) oxide in a test tube
similar to the one shown. After
the chemical reaction, you find
12.5 g of liquid mercury and 1.0
g of oxygen gas. There is no
mercury(II) oxide left in the test
tube.
How much mercury(II)oxide
did you start with? Show your

This graph gives information on changes in sea ice extent in the arctic ocean over a 30-year span. the overall trend shows in the ice extent. to address the trend, scientists need to ask themselves, one direct consequence of the trend is that

Ethanol (c2h5oh) is produced from the fermentation of sucrose in the presence of enzymes. c12h22o11(aq) + h2o(g) 4 c2h5oh(l) + 4 co2(g) determine the theoretical yield and the percent yields of ethanol if 680. g sucrose undergoes fermentation and 326.5 g ethanol is obtained. theoretical _ g _ percent %
