305 x 4 = 1220.
1/4 of 304 = 76.
1220 + 76 = 1296.
You'd need approximately 4 and 1/4 of glasses of milk to get the recommended calcium intake for teenagers.
Both compare the rate of population growth.
Answer:
The most stable conformer would be the anti-conformer when the substituent methyl groups are farthest away from each other.
Explanation:
Isomers are chemical compounds with the same molecular formula but with different molecular structures.
Conformers are a special type of isomers that produce different structures when the substituents of a Carbon-Carbon single bond (C-C) are rotated.
In 2,3 dimethyl butane, the substituent methyl groups are located around the second and third Carbon to Carbon single bond.
To achieve a stable configuration, the methyl group substituents need to be as far apart as possible (that is, in an anti-position) to minimise repulsion.
The closer the methyl groups are to each other, the more they repel each other and the more unstable the conformer becomes.
<u>Answer:</u> The correct option is Option D.
<u>Explanation:</u>
Significant figures are defined as the figures that represent the digits of a number which carry an important contribution to the numerical value, starting with the first non-zero digit. For Example: 105.268 has 6 significant figures because every digit carry its own contribution towards the numerical value.
Whenever there is multiplication, the answer will contain the same number of significant figures as there are in the least precise numerical value.
Significant figures in 8.01 are 3 and that in 4.1 are 2.
So, the answer of these two numerical value will contain 2 significant figures.
Hence, the correct option is Option D.
all of the absorbed energy is converted to kinetic energy
Explanation:
When a gas is heated, all of the absorbed energy is converted to kinetic energy. This is because, according to the kinetic theory of gases, the average kinetic energy of gases is directly proportional to temperature.
- As the gas absorbs more heat, the potential energy it carries converted to kinetic energy.
- Potential energy is the energy at rest of a body
- Kinetic energy is the energy due to the motion of the particles of a medium.
- As more heat is added to a body, the kinetic energy continues to increase significantly.
- Eventually, all the absorbed energy is converted to kinetic energy as the gas expands more.
