Answer:
The Ka value used for the buffer system is :- Ka2 = pKa2 = 7.2
pH = 7.1
Explanation:
The buffer system given in the question is :-
and
The reaction taking place is:-
The Ka value used for the buffer system is :- Ka2 = pKa2 = 7.2
The pH can be calculated as:-
pH = 7.2 + log 0.40/0.50 = 7.1
D. all of these
Explanation:
All of given choices are the physical properties of the gold as given by the table.
Color is also a physical property.
Ionization potential and electronegativity are chemical properties of the metal.
The physical property of a substance tells us everything about a substance when no change is occurring to it.
Such properties are observed with our sense or instruments or pieces of apparatus.
- Examples are color of matter, state of matter, odor, taste, density, boiling point, melting point, solubility, hardness, texture etc

Answer: Particles in all states of matter are in constant motion and this is very rapid at room temperature. A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. ... Individual particles in liquids and gases have no fixed positions and move chaotically.
