Answer: Temperature.

Explanation:

Thermal energy is defined as the internal energy of an object because of the kinetic energy present within the molecules of the object.

As relation between kinetic energy and temperature is as follows.

        K.E = \frac{3}{2}kT

So, with increase in temperature there will also occur an increase in kinetic energy which leads to an increase in thermal energy of the substance.

Therefore, we can conclude that by applying heat, Bela increased the thermal energy of the eggs. She could measure how much the temperature increased with a thermometer.

Identify the structure of a minor product formed from the radical chlorination of propane, which has molecular formula C3H6Cl2 a
Novosadov [1.4K]

Answer:

             As we are not provided with ¹H-NMR spectrum therefore we can not conclude a single result for the minor chlorination of propane with Molecular formula C₃H₆Cl₂.

Hence, we will draw all the possible isomers with molecular formula C₃H₆Cl₂ and predict the ¹H-NMR spectrum for each of them separately.

Below is the structures of possible minor products and the NMR spectrum respectively.

Possible Product A:

                                If the minor product formed is 2,2-Dichloropropane then it will give only one singlet peak in NMR spectrum.

Possible Product B:

                               If the minor product is 1,1-Dichloropropane then it will exhibit two triplets and one multiplet as shown in figure.

Possible Product C:

                               If the minor product is 1,2-Dichloropropane then it will give four peaks in NMR. The extra peak is formed due to two enantiomers about the chiral carbon.

Possible Product D:

                               If the minor product is 1,3-Dichloropropane then it will exhibit one triplet and one quintet signal as shown in figure.

There are 6.022 x 10^23 atoms of Hg in 1 mole of Hg. The number of atoms in 4.5 moles of Hg can be found by multiplying 4.5 by 6
serious [3.7K]

Answer:

D. 27.099 x 10²³.

Explanation:

  • It is known that every 1.0 mole of an atom contains Avogadro's no. (6.022 x 10²³) atoms.

<em>So, 4.5 mol of Hg will contain:</em>

(4.5 mol)(6.022 x 10²³) = 27.099 x 10²³ atoms.

<em>So, the right choice is: D. 27.099 x 10²³.</em>
