The pH of pure water is neutral because the concentration of hydronium ions equals that of hydroxide ions.
Answer: Option A
<u>Explanation:</u>
Water is one of the most important constituents of living being. It is said that there is no life without water. So that water need to neutral in nature to save life. Pure water is composed of hydronium
and hydroxide
ions. It is known that hydronium ions are acidic in nature with concentration of
.
Similarly, the hydroxide ions which are basic in nature will be in same concentration as that of hydronium ions. So, as the concentration of basic and acidic elements are equal with the same strength of pH, the combination of these ions lead to formation of pure water with the pH being neutral.
C. Sulfur and oxygen (non metals) forms a covalent bond while the magnesium (a metal) will react with both non metals to form an ionic bond
1) is chemical Bonds
3) Conservation of mass
5) compound
hope i helped on the ones i could answer
The reason nonmetals are electrical insulator is since
valence shells in nonmetal atoms are almost full, the atoms attract electrons
and hold them tightly to fill their valence. The reason why it acts as an
insulator is the high ionization energy it has. It prevents any electron from
leaving an atom easily even when an electric field is applied.
Answer:
It verified J. J. Thomson's work on the atomic structure. It concluded that an electron circles a nucleus in a fixed-energy orbit.
