Answer:
1. John Dalton is credited with the first modern atomic theory, as explained in his A New System of Chemical Philosophy. 2. In the physical sciences, subatomic particles are smaller than atoms. They can be composite particles, such as the neutron and proton; or elementary particles, which according to the standard model are not made of other particles. Particle physics and nuclear physics study these particles and how they interact. 3.Find the Least Common Multiple of the denominators (which is called the Least Common Denominator).
Change each fraction (using equivalent fractions) to make their denominators the same as the least common denominator.
Then add (or subtract) the fractions, as we wish!
4. You might observe and measure such properties as color, odor, texture, density, boiling point, and freezing point. ... Other properties, such as density, can be used to identify substances. They do not vary from one sample of the same substance to another.
