Answer:
The particles in a solid are tightly packed and locked in place. ... The particles in a liquid are close together (touching) but they are able to move/slide/flow past each other. The particles in a gas are fast moving and are able to spread apart from each other.
Explanation:
There’s only one measurement the question doesn’t make sense
Answer:
No, i will not use a water pipe consisting of the two metals
Explanation:
Looking at the reduction potential of the both metals, it is clear that an electrochemical cell is set up with iron as the anode and copper as the cathode.
This will make the iron to quickly corrode and eventually destroy the water pipe. It is better to have a set up in which another metal that is higher than iron in the electrochemical series is combined with it.
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
%
