Explanation:
If the pH of a solution is 3, its pOH is 14-3= 11
Answer:
true
Explanation:
There are two electrons (in the 1s orbital) on both carbon and fluorine “shielding” the outer electrons from the full force of the nucleus and due to both atoms being approximately the same size (both period two) then it is this shielding effect and proton difference that is causing the electronegativity difference
Answer:
see explanation
Explanation:
The process of ionization to produce cations is endothermic. For formation of Ca⁺² two ionization steps need be illustrated as follows...
1st ionization step: Ca° + 590Kj => Ca⁺ + e⁻
2nd ionization step: Ca⁺ + 1151Kj => Ca⁺² + e⁻
