He worked with large numbers of plants.
Answer:
The correct option is: b. the side chain
Explanation:
Amino acids are biomolecules that contain an alpha-carbon (α-C) attached to two functional groups- carboxyl group (-COOH) and amine group (-NH₂), and an organic side chain (-R).
<em>The carboxyl and amine functional groups are common in all amino acids but the </em><u><em>side chain is distinctive to each amino acid.</em></u>
<u><em>Thus the amino acids can be easily classified on the basis of the properties of this organic side chain</em></u>.
<u />
<u>Therefore, the various amino acids have different side chains.</u>
The given condition is STP, under this condition, gas has a rule of 22.4 L per mole. And the given equation is already balanced. The ratio of mole number is the same as the ratio of the volume and is also the same as the ratio of coefficients. So the answer is 4.0 liters.
Answer:
Mass, gravitational force and height
Explanation:
Potential energy of body is the energy at rest in a body and it depends on the mass, acceleration due to gravity and height of a body;
Potential energy = mass x gravity x height = mgh
The more the mass, gravity and height of a body, the higher the potential energy a body will posses. This is why a stone at a height has more potential energy than one on the ground.
This process involves the dilution of the 12 molar HCl. To reduce the concentration, we need to set up an equality so that we know how much of the 12M we need to make the 3.5M.
12 moles HCl 3.5 moles HCl
——————— = ———————
1 Liter of Soln ‘x’ Liters of Soln
Notice that the 12 moles over the 1 liter is equal to 12 molar; in doing this, we’re maintaining the concentration of the initial HCl. By setting it equal to the 3.5 over ‘x’, we’re still maintaining the concentration.
After solving, we find that ‘x’ equals 0.292. This value means that in 0.292 liters of our 12 M HCl solution, there are 3.5 moles of HCl. But, we’re not done yet.
0.292 liters of 12 M HCl can make 1 liter of 3.5 M HCl, but the question asks for 1.5 liters. To get this, multiply 0.292 liters by 1.5, and the new result, 0.4375, represents the amount of 12 M HCl required to prepare a 1500 mL 3.5 M HCl solution.
