Dalton viewed chemical change as the process of atom rearrangement. Using the atomic theory he came up with, he believed that chemical reactions rearranged the atoms into different combinations.

Why dissolution of NaCl in water is a physical change not a chemical change?
It has been argued whether this is a chemical or physical change. It can be viewed as a chemical change since the Na ion and Cl ion are separated from the crystal lattice, and then become hydrated by water molecules, thus changing the actual chemical structure. However, this is a REVERSIBLE chemical change. Thus, if you evaporate the water, you end up with the same crystalline structure (lattice) that you began with, and so it may now be viewed as simply a physical change. There is no consensus as to which is correct, IMHO.
Will bromine gas get darker if there is a lot of it?
Bromine gas, like any other transparent colored substance, will appear darker if viewed through a thick layer than through a thin one. Otherwise, the color does not change with amount of material.
The most acidic compound is methyl alcohol?
No, methyl alcohol is generally not viewed as an acid at all.
What are 4 examples of chemical properties?
A chemical property is whichever of a substance's properties that develop into obvious for the duration of a chemical rejoinder that is any superiority that can be recognized merely by varying a material's substance individuality. Minimally language, substance properties cannot be established immediately by screening or poignant the essence substance's interior construction must be influenced for its chemical properties to be explored. On the other hand catalytic possessions would also be substance chattels. Chemical properties can be differenceed with corporeal properties which can be distinguished devoid of altering material's configuration. However for loads of properties surrounded by the capacity of corporal chemistry and supplementary disciplines at frontier among chemistry and physics the peculiarity may be a subject of researcher's outlook. Material properties both corporal and chemical can be viewed as supervenient. Several layers of superveniency are potential. Substance properties can be utilized for construction substance arrangements. They can also be constructive to classify an unidentified material to take apart it from other substances. Materials knowledge will in general think about the substance properties of a material to channel its submissions.Some chemical properties are Heat of combustion, Enthalpy of formation, Toxicity, Chemical stability in a given environment, Flammability (The ability to burn), Preferred oxidation state(s), Coordination number. Chemical Properties are domestic properties which are not exhibited peripherally.
What is glass plate as laboratory apparatus?
== == You put a specimen on a glass plate and then view the specimen under a microscope. It acts sort of like a slide.
Expectations that change how results are viewed?
There are many different kinds of expectations that can change how results are viewed. Expecting a reaction to produce a chemical in a certain amount of time can change how results are viewed for example.
When a new substance is produced is it a chemical or physical change?
That's a chemical change because the structure of the atoms are changing. Chemical features can only be viewed through chemical change, by the way.

How resutls are viewed?
Expectations change how results are viewed
What are the negatives of the practice?
Negative staining does not change the chemical structures within cells, it simply outlines the cell structure allowing the cell to be viewed easier.
