Answer:
It could be because of rounding error somewhere in your calculations. Another thing to note is 90 +/- 4 g/mol.
Your calculations don't have to be spot on.
Answer:
it will turn blue black to any substance
342.15 g/mol is the molar mass of Al2(SO4)3 Aluminium sulfate, This is what I found I hope this is right. Hope this helps;)
Hope u do well :) ik this maybe hard but you’ll get through it , the answer is D !
<h3><u>Answer;</u></h3>
Cations are much smaller than their corresponding parent
<h3><u>Explanation;</u></h3>
- Parent atom has more electrons and thus the effective nuclear charge on each electron is less.
- When a cation is formed electron(s) is/are lost. Thus the effective nuclear charge or simply put, the attraction of the nucleus towards the electrons increases. Therefore, due to greater pull, the nucleus pulls the shells towards it, there by reducing the size, which makes cations smaller than their corresponding parent.
