The mass given in the periodic table is a weighted average of all isotopes of an element. For example Hydrogen is normally just one proton so one would expect its atomic mass to be exactly 1, but there are other naturally occurring isotopes of H (deuterium with a mass of 2 and tritium with a mass of 3)  that have more neutrons resulting in a weighted average slightly greater than 1.

The mass of the atoms is given by the number of neutrons and protons. The mass of the atom and the average mass of the element looks a little different due to mass defect.

The mass defect has been the difference in the mass and the average mass of the elemental atom. It has been the energy that binds the neutrons and the protons together in the nucleus. The mass and the average atomic mass differ slightly.

The mass of an individual atom differs from the average atomic mass as average atomic mass is the sum of the masses of the isotope of the elements. Isotopes have little difference in masses due to the number of neutrons. For example mass and average atomic mass of hydrogen differs.

The compound with ionic bonding is LiBr (b), which consists of a lithium ion (Li⁺) and a bromide ion (Br⁻) held together by electrostatic attraction.

Ionic bonding occurs between a metal and a non-metal, where the metal loses one or more electrons to become a cation (positively charged ion) and the non-metal gains one or more electrons to become an anion (negatively charged ion). The resulting oppositely charged ions are held together by electrostatic attraction, forming an ionic compound.

In the case of LiBr, lithium (Li) is a metal that easily loses one electron to form a Li⁺ ion, while bromine (Br) is a non-metal that readily gains one electron to form a Br⁻ ion. The resulting Li⁺ and Br⁻ ions are strongly attracted to each other by their opposite charges, forming the ionic compound LiBr.

In contrast, compounds such as S (a), H₂O (c), Na (d), and He (e) do not have ionic bonding. S and Na are both elements and do not form ionic compounds with themselves. H₂O is a covalent compound that shares electrons between its atoms, while He is a noble gas that exists as a single atom and does not form chemical bonds with other atoms.

Explanation:

Answer: dense

Explanation:

Answer:

The heat required to boil water is called the heat of vaporization, and it is the amount of energy required to change the state of a substance from a liquid to a gas at a constant temperature. The heat of vaporization for water is approximately 40.7 kJ/mol or 2257 J/gram.

To calculate the heat required to boil 50.0 grams of water, you would multiply the heat of vaporization (2257 J/g) by the number of grams of water:

Heat (J) = 2257 J/g x 50 g

Heat (J) = 112,850 J

To convert Joules to kilojoules (kJ), divide by 1000.

Heat (kJ) = 112,850 J / 1000 = 112.85 kJ

Therefore, it takes 112.85 kJ of heat to boil 50.0 grams of water.

The diene that reacts with one equivalent of HBr to form the two bromoalkene products described in the question can be drawn as follows:

    H          H

    |          |

H3C-C=C-CH2-CH=CH2

    |          |

    H          H

In this diene, there are two double bonds, one between carbons 2 and 3 and another between carbons 4 and 5. When one equivalent of HBr is added to this diene, an electrophilic addition reaction occurs in which the H and Br add to the two double bonds to form two different products, as described in the question.

The effect of increasing temperature on the relative amount of each product can be explained by considering the mechanism of the reaction. The reaction proceeds through a carbocation intermediate, which is formed by protonation of the diene with HBr. The carbocation intermediate can then react with Br- to form the bromoalkene products.

Product 1 is formed by the addition of HBr to the double bond between carbons 2 and 3, which results in the formation of a more stable tertiary carbocation intermediate. As the temperature increases, the reaction rate increases, which can lead to a higher proportion of product 1 being formed. However, at very high temperatures, the reaction rate can become too fast, leading to increased side reactions such as rearrangements, which can decrease the relative amount of product 1.

Product 2 is formed by the addition of HBr to the double bond between carbons 4 and 5, which results in the formation of a less stable secondary carbocation intermediate. As the temperature increases, the reaction rate also increases, which can lead to a higher proportion of product 2 being formed. However, at very high temperatures, the reaction rate can become too fast, leading to increased side reactions such as elimination, which can decrease the relative amount of product 2.  Therefore, the answer to the question is that as the temperature increases, the relative amount of product 1 is expected to increase, while the relative amount of product 2 is expected to decrease due to side reactions. However, at very high temperatures, both products can be affected by side reactions, and the relative amounts may not change significantly.
