Answer:
2:3
You'd need 33.3 moles of potassium chlorate, KClO3 , to produce that much oxygen. Notice that you have a 2:3. mole ratio between potassium chlorate and oxygen gas, which means that, regardless of how many moles of the former react, you'll always produce 3/2 times more moles of the latter.
Explanation:
Use mv=mv, plug in the know 1x9.24=3m. Solve for m, which m is 3.08M
Answer:
Coal, crude oil, and natural gas are all considered fossil fuels because they were formed from the fossilized, buried remains of plants and animals that lived millions of years ago. Because of their origins, fossil fuels have a high carbon content.
Explanation:
Answer:
A decrease in entropy is balanced by a large increase in the entropy of the surrounding water molecules.
Explanation:
Water's ability to dissolve a wide variety of molecules is important, but more important is the hydrophobic effect, which drives the aggregation of hydrophobic molecules and plays a role in the folding of proteins and formation of lipid-bilayers.
Entropy is a measure of disorder of a system. Forcing water to be ordered decreases entropy, a very unfavorable situation. Water has the ability to force hydrophobic molecules away causing their aggregation. Water gains entropy when the fatty acids (hydrophobic) are forced into the lipid-bilayer. Thus, a decrease in entropy is balanced by a large increase in the entropy of the surrounding water molecules.
