Answer:
dispersion, in chemistry, mixture in which fine particles of one substance are scattered throughout another substance. A dispersion is classed as a suspension , colloid , or solution . Generally, the particles in a solution are of molecular or ionic size; those in a colloid are larger but too small to be observed with an ordinary microscope; those in a suspension can be observed under a microscope or with the naked eye. A coarse mixture (e.g., sand mixed with sugar) is usually not thought of as a dispersion.
Answer:
hydrogen, nitrogen, oxygen, flourine, chlorine, iodine, bromine
Explanation:
they are very reactive and thus cannot exist as monoatomic elements
Sulfur is an element in the periodic table that has a chemical symbol of S. This element is the 16th element in periodic table. This means that the atomic number or number of protons in the nucleus of the atom is equal to 16.
The number following the name of the element is the mass number. The following are the complete symbol that are arranged as follows:
chemical symbol - atomic number - mass number
*Sulfur-32
S - 16 - 32
*Sulfur-33
S - 16 - 33
*Sulfur-34
S - 16 - 34
Answer:
c. The atoms of one element can be identical to the atoms of another element.
Explanation:
<em>Which of the following is not a statement of Dalton's atomic theory of matter?</em>
<em>a. Elements are made of atoms.</em> TRUE. An atom is the smallest particle of a chemical element that can exist.
<em>b. Atoms of a given element are identical.</em> TRUE. The only slight difference is in the mass of isotopes.
<em>c. The atoms of one element can be identical to the atoms of another element.</em> FALSE. The atoms of different elements are different from one to another.
<em>d. A given compound always has the same number and kinds of atoms. </em>TRUE. This is known as Dalton's law of constant composition.
