Answer:
yo gotta be more specific
Explanation:
look in the picture for the answer
Answer:
Explanation:
The mass percentages of chlorine and fluorine:
Given:
Mass of chlorine = 5.753g
Mass of fluorine = 9.248g
Find the total of the masses given:
Total mass = mass of chlorine + mass of fluorine = 5.753 + 9.248 = 15.001g
% of Cl = 
x 100
% of Cl = 
x 100 = 38.35%
% of F = 
x 100
% of F = 
x 100 = 61.65%
Answer:
Isotopes of bromine have same chemical properties because they have same number of electrons.
Isotopes have only different number of mass that does not affect it's chemical properties too much.
Answer:
It is the minimum amount of analyte that produces a signal which can be measured with reasonable accuracy - LOQ
The concentration is equal to three times the standard deviation of the signal from the blank divided by the slope of the calibration curve - LOD
The concentration is equal to 10 times the standard deviation of the signal from the blank divided by the slope of the calibration curve - LOQ
It is the minimum amount of analyte that produces a signal that is significantly different from the blank - LOD
Explanation:
We define the limit of detection has the lowest amount of analyte that produces a signal that is significantly different from a blank solution ( the absence of the substance). It is calculated as three times the standard deviation of the signal from the blank divided by the slope of the calibration curve.
The limit of quantitation (LOQ) is defined as the minimum amount of analyte that produces a signal which can be measured with reasonable accuracy. It is measured as 10 times the standard deviation of the signal from the blank divided by the slope of the calibration curve.
