Fluorine has the highest. Fluorine's electronegativity is 4.0
C. a chemical reaction occurred when the two liquids were mixed
Answer:
The percentage deviation is
%
Explanation:
From the question we are told that
The concentration is of the solution is 
The true absorbance A = 0.7526
The percentage of transmittance due to stray light
% 
Generally Absorbance is mathematically represented as

Where T is the percentage of true transmittance
Substituting value



%
The Apparent absorbance is mathematically represented

Substituting values


= 0.7385
The percentage by which apparent absorbance deviates from known absorbance is mathematically evaluated as


%
Since Absorbance varies directly with concentration the percentage deviation of the apparent concentration from know concentration is
%
Answer:Acid+Base--> salt+water
Explanation:the reaction between acids and bases is called neutralization and will always produce salt and water
