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.
Answer: electron–negative, neutron–neutral, proton–positive
Explanation:
Atom is made up of three subatomic particles named protons, neutrons and electrons. Both protons and neutrons are found inside the nucleus of the atom, while electrons are found outside the nucleus of the atom. The charge distribution are as follows:
- The proton carry a positive charge
- The neutron carry no electric charge (i.e electrically neutral)
- The electron carry a negative charge
Answer: yes
When the concentration of all the reactants increases then the rate of reaction increases. When the concentration decreases then the rate of reaction decreases.
This all because more molecules or ions form new compounds. Or losses.
