Q:

SI unit of equivalent conductance

A) ohm/cm B) Siemens m2/equivalent
C) Siemens/equivalent D) mho/cm
 
Answer & Explanation Answer: B) Siemens m2/equivalent

Explanation:

SI_unit_of_equivalent_conductance1556274980.jpg image

 

Equivalent conductance is defined as the conductance of an electrolyte solution containing one gram equivalent of the electrolyte. It is equal to the product of specific conductance (k) of the solution and the volume (V) of the solution that contains one gram equivalent of the electrolyte.

 

 λ = k x V

 

Unit of spceific conductance k is Siemens / m.

 

Volume of the solution V is m3

 

Now, required equivalent conductance unit is Siemens.m2/equivalent .

Q:

What is the product of a number and its reciprocal?

A) 0 B) 1
C) -ve of the number D) the number itself
 
Answer & Explanation Answer: B) 1

Explanation:

The product of a number and its reciprocal is always equals to 1.

 

For Example : Let the number be 4.

Now, its reciprocal is 1/4

Hence, required product = 4 x 1/4 = 1.

 

Now, take the number as -15.

Then its reciprocal is -1/15

Required product = -15 x -1/15 = 1.

 

Hence, the product of a number and its reciprocal is 1.

Q:

A plane is an undefined term because it

A) is a flat surface that extends indefinitely in all directions B) is where other geometric shapes can be constructed
C) is described generally, not using a formal definition D) can be named using three noncollinear points
 
Answer & Explanation Answer: C) is described generally, not using a formal definition

Explanation:

In geometry, we can define plane as a flat surface with no thickness.

The surface extends with no ends.

A plane does not have any edges even if we draw it on paper with edges, it does't mean it has edges.

 

Hence, A plane is an undefined term because it is described generally, not using a formal definition.

A) 139.54 B) 140.70
C) 149.08 D) 153.24
 
Answer & Explanation Answer: C) 149.08

Explanation:

The gram formula mass is nothing but molar mass.

 

Composition :

 

Symbol      Element       Atomic weight       Atoms
   

     P         Phosphorus       30.973762               1       = 30.973
   

     O         Oxygen             15.9994                  4       =  63.998
   

     N         Nitrogen            14.0067                  3       =  42.020
   

     H         Hydrogen          1.00794                  12      =  12.096

   

Total   =  30.973+63.998+42.020+12.096 = 149.087
