Sulfur
Explanation:
Sulfur has 16 valence electrons, as shown in the diagram.
Answer:
A. The kinetic molecular theory relates the properties of a state of matter to the motion of its molecules.
Explanation:
The higher the kinetic energy of the molecules, the faster its movement will be. The state of a matter will depend on how fast the molecules move. When the molecules barely move, it will be packed tightly and its state will be solid. If the molecules kinetic energy rises, eventually they start moving around and the state will be liquid. If the kinetic energy rises further, the molecule will expand and changed into gas form.
Answer:
Number of protons
Explanation:
Elements are arranged in the periodic table in an order of increasing number of protons. It's called the proton number or atomic number.
Answer:
pH = 11.3
Explanation:
From the question given above, the following data were obtained:
Concentration of hydronium ion [H₃O⁺] = 4.950×10¯¹² M
pH =.?
The pH of a solution is defined by the following equation:
pH = –Log [H₃O⁺]
Thus, with the above formula, we can obtain the pH of the solution as follow:
Concentration of hydronium ion [H₃O⁺] = 4.950×10¯¹² M
pH =.?
pH = –Log [H₃O⁺]
pH = –Log 4.950×10¯¹²
pH = 11.3
