States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

Transcribed Image Text:Question 23
Which of the following is INCORRECT?
O Calibration determines the relationship between the analytical response and the
concentration of analyte.
O The range in the calibration curve between the relationship of analytical response
and concentration of analyte is the concentration interval over which linearity,
accuracy, and precision are all acceptable.
O The detection limit (DL) or also known as the limit of detection (LOD) is the
smallest concentration that can be reported with a certain level of confidence.
O In external standard method, the signal (SA) is inversely proportional to the
concentration of analyte (CA). Therefore, the formula is SA=KACA where the k is
method's sensitivity.
