They use the Scientific Method.
The Scientific Method is made up of steps scientists take to draw a conclusion
Step 1: Form a Question
Step 2: Research the Question
Step 3: Form a Hypothesis (educated guess)
Step 4: Conduct an Experiment (use quantitative and qualitative data)
Step 5: Form Your Conclusion Based on Results

This should help....

Can someone please explain me the difference between physical changes and physical properties and of chemical changes and chemic
morpeh [17]

Answer:

Explanation:

Physical properties and physical change:

Physical properties are the properties of substance that do not involve the change in to another matter while the process through which change is happen is called physical change.

For example,

Melting point is physical property and the process "melting" is called physical change.

Freezing point is physical property and the process "freezing" is called physical change.

Chemical property and chemical change:

Chemical property is the ability of substance to change into another substance while the process through through which it is happen is called chemical change or chemical reaction.

For example:

The chemical property of iron is to react with oxygen and form rust. This process or chemical change is called corrosion. So corrosion is chemical change.

Hydrocarbon react with oxygen and form water and carbon dioxide. It is the chemical property. While the process is called combustion so combustion is a chemical change.

For the reaction
PilotLPTM [1.2K]
We are asked to find the value of ΔG°rxn from the equilibrium concentrations of the reactants and products. We can use the following formula:

ΔG°rxn = -RTlnK

The value of R = 8.314 J/Kmol, T = 298.15 K and we are given the equilibrium constant Keq = 2.82.

The question provides equilibrium concentrations and then asks to find ΔG°rxn when more of a product is added to the reaction mixture. However, you are asked to find ΔG after the reaction has settled down and reached equilibrium once more. Therefore, we can simply use Keq = 2.82 still and solve for ΔG.

ΔG°rxn = -(8.314 J/Kmol)(298.15 K)(ln(2.82))
ΔG°rxn = -2570 J/mol
ΔG°rxn = -2.57 kJ/mol

Under equilibrium conditions at standard temperature and pressures, the value of ΔG°rxn = -2.57 kJ/mol.
