Answer:

The correct answer is  B) Cl and Mg

Explanation:

An ionic bond is produced by the union of a cation and an anion. In this case, Mg would be the cation and Cl the anion. They will form the compound Magnesium Chloride (MgCl2):

Mg + Cl2 ----> MgCl2

Mg belongs to group 2 of the periodic table, that is, it has two valence electrons. In the case of Cl, it is in group 7 and has seven valence electrons (requires one electron to complete the octet).

The table shows the specific heat of four substances. The substances are exposed to the Sun for the same length of time. Arrange
Kazeer [188]

Answer: The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. Therefore, a high value of specific heat would mean that more heat is needed in order for the temperature to increase. The correct answer would be water since it has the highest specific heat of the choices given.

Which element from this portion of the table chemically reacts in a way similar to the way the element chlorine (Cl) reacts? (1)
mina [271]
D. I or Iodine

This is because they are both in the same periodic family (the halogens) and thus the number of valence electrons are the same

Explain how intermolecular attractions between molecules influence the bulk of properties of a material
irina1246 [14]

Answer:

<em><u>Intermolecular forces determine bulk properties, such as the melting points of solids and the boiling points of liquids. Liquids boil when the molecules have enough thermal energy to overcome the intermolecular attractive forces that hold them together, thereby forming bubbles of vapor within the liquid.</u></em>
