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.

What is the complete ionic equation for
murzikaleks [220]

Answer:

what  is  the  net  ionic equation

H2SO4(aq) + Cal2(aq) → CaSO4(s) + 2Hl(aq)?

A. H++ SO42- + Ca2+ + 21 → CaSO4 + H+ +1-

B. 2H+ + S042- + Ca2+ + 21° → Ca2+ + SO42- + 2H+ + 21

C. S042- + Ca2+ → CaSO4,

D. 2H+ + SO42- + Ca2+ + 2I- → CaSO4 + 2H+ + 2I-

cancel  the spectator  ion that is the  ions  which  does  not take  place in  the  reaction

for this  case  is  2 H^+  and 2 i^-

Sulfur dioxide, SO2(g), can react with oxygen to produce sulfur trioxide, SO3(g), by the following reaction
WITCHER [35]

Answer:

The heat produced is -15,1kJ

Explanation:

For the reaction:

2SO₂+O₂ → 2SO₃

The enthalpy of reaction is:

ΔHr = 2ΔHf SO₃ - 2ΔHf SO₂

As ΔHf SO₃ = -395,7kJ and ΔHf SO₂ = -296,8kJ

<em>ΔHr = -197,8kJ</em>

Using n=PV/RT, the moles of reaction are:

n = \frac{1,00atm*3,75L}{0,082atmL/molK*298,15K} = <em>0,153 moles of reaction</em>

As 2 moles of reaction produce -197,8kJ of heat, 0,153moles produce:

0,153mol×\frac{-197,8kJ}{2mol} = <em>-15,1kJ</em>

<em></em>

I hope it helps!
