Answer:
It depends on the number of significant figures you are changing to
Explanation:
6.02×1023=6158.46
1 sig fig = 6000
2 sig fig = 6200
3 sig fig = 6160
4 sig fig = 6158
5 sig fig = 6158.5
6 sig fig = 6158.46
When solving significant figures you have to consider the number after each number like in the case of changing to two sig fig the number following one is five and when the number is up to or greater than five you add a value of one to the number before it. But in a case where the number is less than five you just leave it like that like in the case of changing to one sig fig
Gallium sulphate I belive thats it dont count me on that tho
No,they just separate away from each other
B because I’m 100% is currect
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.
