Answer:
never true is the answer
explanation:
compounds are formed by two or more elements that are chemically combined with one another. They can be broken down only be chemical or electro chemical means not by physical means.
hence, the answer i have given above is correct
please mark as brainliest
Oxygen. Is the correct answer
Oxygen has the same number of valence electrons as sulfur. An ion can be an element that gained or lost an electron.
Bonding electrons are involved in chemical bonding these electrons have their valnce shell incomplete
Answer:
FAS concentration = 1.61*10^-4M
Explanation:
Beer Lambert's law relates the absorbance (A) of a substance to its concentration (c) as:
where ε = molar absorption coefficient
l = path length
A plot of 'A' vs 'c' gives a straight line with slope = εl
In addition absorbance (A) is related to % Transmittance (%T) as:
A = 2-log%T----(2)
For the FAS solution, the corresponding calibration fit is given as:
y = 3678(x) + 0.056
This implies that the slope = εl = 3678
It is given that %T = 25.6%
Based on equation(1):
