Find the grams in 1.26x10^-4 mol of HC2H3O2

Biology

-Dominant- [34]3 years ago
6 0
<span> All you have to do is take the number of moles you have a multiply by the molar mass. The number of moles is given. To find the molar mass, add the atomic weights that make up your molecule.

Four hydrogen = Four amu (4*1)
Two carbon = 24 amu (2*12)
Two Oxygen = 32 (2*16)

Summing these, we have a molar mass of 60 grams/mole.

Multiply this by the number of moles and we get:

60(g/mol) * 1.26*10^-4 mol = .00756 g. </span>

Why is negative feedback often associated with maintaining homeostasis?
Pavlova-9 [17]

Answer:

Maintenance of homeostasis usually involves negative feedback loops.

Explanation:

These loops act to oppose the stimulus, or cue, that triggers them. For example, if your body temperature is too high, a negative feedback loop will act to bring it back down towards the set point, or target value, of 98.6

When an organism uses fatty acids, the ester linkages of triacylglycerols are hydrolyzed by enzymes called _____.
Brums [2.3K]

When an organism uses fatty acids, the ester linkages of triacylglycerols are hydrolyzed by enzymes called lipases.

Lipases hydrolyze triglycerides into their constituent fatty acid and glycerol molecules. Lipase digestion starts in the lumen of the small intestine. The surface tension of the fat droplets is decreased by bile salts so that the lipases can hydrolyze the triglyceride molecules.
