A solution can have more than one solutes. 2. In a solution either solute or solvent can be in a greatest quantity. Electrolytes are bad conductors of electricity. 3. Most Molecular compounds are nonelectrolytes. 4. 5. Oxidation is a process of receiving electrons. 6. An electromagnetic radiation can travel through vacuum As the wavelength of an electromagnetic radiation decreases its frequency also 7. decreases. one wavelength is polychromatic. Radiation composed of only 8. 9. Enthalpy (H) is an intensive property 10. The value of state function depends on the path the system took to reach that state. (7 Marks) Q2. Fill in the Blanks. 1. Solutions in which water is the dissolving medium are called and are The two components of a solution 2. -and Work (W) is defined as the product of 3. The Energy due to motion is called 4. The solution of Mg(NO3)2 (aq) Will oxidize which metal K, Cu, Zn 5.

Answer 1

1. True ( maybe like preparing sugar and salt together in water so possible simultaneously two or more solutes in one solution)
2. False ( in a solution one with lower quantity is called solute one with higher quantity is called solvent
3) False ( electrolyte is a charged ion, which promotes electricity conduction)
4) False ( Many but not most like sugar and ethanol are example don't conduct)
5) False ( Oxidation is loss of electrons)
6) True ( like sunrays traveled to earth through a vacuum)
7) False ( they are inversely related)
8)False ( if the single wavelength is present it is called monochromic)
color is dependent on wavelength like VIBGOR in Light due to the differnt wavelength
Chromic mean color, if poly means many, polychrome mean many colors)
9)False ( it depend upon the quantity of matter)
10) Falso ( A state function is a property whose value does not depend on
the path is taken to reach that specific value)
