Answer: C
Here is how I used Process of Elimination:
An hypothesis is your guess before you conduct the experiment.
An inquiry is when you ask for information.
A law is a statement based on repeated experiments.
The answer had to be conclusion.
Hope it helps!
During a collision, the person would most likely experience the same conditions with or without a seatbelt.
The correct answer of gibbs free energy is -232 KJ.
ΔG = -nFE° = -2*96485*1.20 = -232 (kJ)
The Gibbs free energy of a system at any point in time is defined as its enthalpy minus the product of its temperature times its entropy. Because it is defined in terms of thermodynamic properties that are state functions, the system's Gibbs free energy is a state function. It is commonly referred to as free energy because it is readily available at all times. If necessary, the reaction can steal this energy without having to pay or work for it. The reaction between sodium chloride and water is regarded as spontaneous, and it has a negative G. When solid NaCl is immersed in water, it begins to dissociate on its own without any external assistance.

The two properties of the ink components that determine their movement along the chromatography paper/fabric are:
the solubility of ink constituent in chemical solvent.
the mixture of colour constituents in the ink.
Explanation:
Chromatography is the process in which the chemicals of the mixture are separated on the basis of constituents.
Capillary action let the colors of ink separate into their constituents. When ink is subjected to solvents it gets dissolve and gets separated.
The property of ink that led to determine their movement is:
Ink is made of many dyes of different colours, pigments etc.
The chemicals that has the best solubility in the chemical will move up on the chromatography paper and fabric.
