Which element would most likely have a positive electron affinity

Chemistry
1 answer:
STatiana [176]3 years ago
7 0

Answer : Electron affinity (Eea) of an atom or molecule can be defined as the amount of energy released or spent when an electron is being added to a neutral atom or molecule in the gaseous state to form a negative ion.


Chlorine is considered to be the element which has highest electron affinity in the modern periodic table.


The general formula is X + e^{-} ----> X^{-} + energy


It is found that nonmetals have more positive Eea than metals.


Electron affinity increases across the group from left to right in the modern periodic table. Elements with small nucleus have high electron affinity.

An ideal gas is contained in a cylinder with a volume of 5.0x102 mL at a temperature of 30°C and a pressure of 710. Torr. The ga
Scorpion4ik [409]

Answer:

51207 torr is the new pressure of the gas

Explanation:

We can solve this question using combined gas law that states:

P1V1T2 = P2V2T1

<em>Where P is pressure, V volume and T absolute temperature of 1, initial state and 2, final state of the gas</em>

<em> </em>

Computing the values of the problem:

P1 = 710torr

V1 = 5.0x10²mL

T1 = 273.15 + 30°C = 303.15K

P2 = ?

V2 = 25mL

T2 = 273.15 + 820°C = 1093.15K

Replacing:

710torr*5.0x10²mL*1093.15K = P2*25mL*303.15K

3.881x10⁸torr*mL*K = P2 * 7.579x10³mL*K

P2 = 51207 torr is the new pressure of the gas

Why CH3Cl has tetrahedral shape
soldier1979 [14.2K]
The central atom is carbon with three hydrogen and one chlorine atom around it. There are no unshared electrons on the carbon so it is tetrahedral.
