<span>Electronegativity is the property of an element that measures the ability of it to attract and form electron bonds. The trend in the periodic table in terms of electronegativity decreases from right to left and from top to bottom. In the case of period 4, the element with the highest electronegativity is bromine. </span>

Answer:

Bromine (Br) has the highest electronegativity.

Explanation:

Electronegativity is a measure of the tendency of an atom to attract the bonding electrons towards itself.

In general, electronegativity increases on moving from left to right across a period. Therefore, the most electronegative elements occupy the rightmost column of the periodic table. This is because, on moving across a period the atomic number increases which increases the nuclear charge on the atom. As a result, the electrons around the vicinity of such atoms feel a strong nuclear pull.

Although, noble gases occupy the last column on the right of the periodic table, they already have completely filled octets and hence in general do not exhibit electronegativity. Therefore, it is the halogen group which precede the noble gases, that are the most electronegative. Period 4, terminates with the halogen, bromine (Br) which is the most electronegative.

Liquids do not have the energy to overcome the ___ and move to the gaseous state.
Ugo [173]

Answer - Inter-molecular attractions

Explanation-

As we know everything around us is made up of matter that means everything has molecules as their basic structure. The state of anything is decided by the spaces between the molecules.

The state of the objects that have strong inter-molecular attractions a solid and gradually the lesser will be in state of liquid and gas. The attraction between the molecules is overcome only when a certain amount of energy is provided from outside.

If the volume occupied by the air in a bicycle pump is 525 cm3, and the pressure changes from 73.2 kPa to 122.5 k.Pa as the pist
Musya8 [376]

Answer:

V_2=313.71\ cm^3

Explanation:

Given that,

Initial volume, V_1=525\ cm^3

The pressure changes from 73.2 kPa to 122.5 k.Pa.

We need to find the new volume occupied by the air. Let it is V₂. It can be calculated using Boyle's law such that,

P_1V_1=P_2V_2\\\\V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{73.2\times 525}{122.5}\\\\V_2=313.71\ cm^3

So, the new volume is 313.71\ cm^3.

If I add water to 100Ml of a 0.75 m NaOH solution until the final volume is 165 ml , what will the molarity of the diluted solut
Mamont248 [21]

Answer:

0.45M

Explanation:

The following were obtained from the question:

C1 = 0.75M

V1 = 100mL

V2 = 165mL

C2 =?

Applying the dilution formula C1V1 = C2V2, the concentration of the diluted solution can be calculated for as follows:

0.75 x 100 = C2 x 165

Divide both side by 165

C2 = (0.75 x 100) /165

C2 = 0.45M

The concentration of the diluted solution is 0.45M
