Answer:
Option-A [<span>Cl (g) + e</span>⁻ <span> → Cl</span>⁻<span> (g)] is the correct answer.
Explanation:
First electron affinity is the amount of heat evolved when an electron is added to a neutral atom.
Such problems often come in questions related to Born-Haber Cycle topic. Let suppose Mg and Cl</span>₂ is reacted to form<span> MgCl</span>₂ crystal.
Then the Cl₂ gas is first atomized as follow,
Cl₂ → 2 Cl
After atomization an electron is added to neutral chlorine atoms, as,
Cl + e⁻ → Cl⁻
So, option A is correct choice.
Answer:
Answer choice C
Explanation:
Neglecting either your own or your child's needs is always a bad idea and is bad for the child, meaning that A is not the correct answer. You should also not expect more of and push your child above their natural ability level, so B is also not correct. However, you should try to discipline and teach your child without hurting them physically or mentally. Therefore, C is the correct answer. Hope this helps!
D please mark I brainliest I need them lol
Among these Options the Option B contains a Balance chemical equation. Equation is as follow,
<span>2Na </span>₍s₎<span> + MgF</span>₂<span> → 2NaF </span>₍s₎ <span> + Mg </span>₍s₎
There are two Na atoms (or moles) at right hand side and two at left hand side.
There are two F atoms (or moles) at right hand side and two at left hand side.
There is one Mg atom (or mole) at right hand side and one at left hand side.
