Final answer:
To calculate the number of moles in an experiment, you need to know the mass of the substance and its molecular weight. The number of moles is then found by dividing the mass by the molecular weight. This applies to any substance, including bromobenzene, magnesium, and benzophenone.
Explanation:
To calculate the number of moles of bromobenzene, magnesium, and benzophenone you will use in the experiment, we first need the molecular weights of each substance. The molecular weights determined from experimental data are crucial to this calculation. The number of moles of a compound is equal to the mass of the compound divided by its molecular mass. For example, if we consider a substance like benzene, the molecular formula is C6H6 which is derived from its empirical formula CH, and the ratio of the elements within it. Let's say you have 'm' grams of bromobenzene, 'n' grams of magnesium, and 'p' grams of benzophenone. Also, let the molecular weights of bromobenzene, magnesium, and benzophenone be 'M', 'N', and 'P' respectively. Then the number of moles of bromobenzene would be m/M, of magnesium would be n/N, and of benzophenone would be p/P. To get the exact values, you would need the specific weights of these substances in your experiment. Remember to ensure that the weights are in grams (for mass) and g/mol (for molecular weight) since the number of moles is a dimensionless quantity.

Answers
Answer: Option (C) is the correct answer.
Explanation:
When two nuclei and a subatomic particle like proton, neutron or high energy electron collide with each other then it results in the formation of two or more different nuclides.
For example,
Whereas in an electrochemical, thermochemical and chemical reaction there occurs change in number of electrons and not in number of protons or neutrons.
Thus, we can conclude that a change in the number of protons or neutrons occurs in nuclear reaction type of reaction.
A change in the number of protons or neutrons occurs inwhich type of reaction? A change in the number of protons or neutrons occurs innuclear reaction. The answer is letter C. The rest of the choices do not answerthe question above.

Answer:
Electron shielding
Explanation:
Ionization energy decreases moving down a group in the periodic table because of a phenomen known as Electron shielding, in which valence electrons do not interact with the positively charged nucleus as strongly as inner electrons do, because these inner electrons shield the valence electrons. This means it's easier for these valence electrons to leave the atom the more inner electrons are between them and the nucleus, this translates into a decreased ionization energy value.
