Answer:
2500kg/m3
Explanation:
Mass=20g= 20×10^-3kg
Volume=8x10^-6m3
<h2>Now we know that Density = mass\volume</h2>
D= 20×10^-3/8×10^-6
=2500kg/m3
Answer:
it's the chloroplast but I'm not sure which on is it it might be the F.
Answer: 0.03798 kilograms
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 
of particles.
To calculate the moles, we use the equation:
1 mole of chlorine gas 
weighs = 71 g
Thus 0.535 moles of chlorine gas will weigh = 
(1kg=1000g)
Thus there are 0.03798 kilograms in 12 L of chlorine gas.
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.
