PH= -log [H+]
= - (log 0.034)
= - (-1.5)
= 1.5

Answer:
Ba
Explanation:
<u>The elements Calcium ( Ca ) and Cobalt ( Co ) , are both present in the same period , and across the period the atomic radius decreases from left to right , since , the atomic number increases , so the electrons increases , which in turns increases the effective nuclear charge , and hence the size decreases , </u>
Therefore ,
Calcium will have bigger atomic radii as compared to Cobalt .
Now,
<u>The elements Barium ( Ba ) and Calcium ( Ca ) are , both are present in the same group , and down the group , atomic radii increases , since , as going down the group , the atomic number increase , so the shells increases , hence the size increases .</u>
Therefore , the atom with the largest radii is Barium .
Answer:
ot means that contains only one kind of matter.
