Answer:
The value is 
Explanation:
From the question we are told that
The bond length is 
The bond dipole moment is 
Generally the dipole moment is mathematically represented as
Here Q is the partial negative charge on the bromine atom
So
=> 
=> 
Generally
1 electronic charge(e) is equivalent to 
So x electronic charge(e) is equivalent to
=> 
=>
Condensation goes with A.
Evaporation goes with C.
Sublimation goes with B.
Freezing goes with D.
My Plate was released to replace the food pyramid and displays the five main food groups. The plate visually shows approximate proportions of the different food groups as opposed tot the food pyramid.
Answer:
Rinse with vinegar solution several times.
Explanation:
The objective of <em>conditioning</em> equipment is that any impurities are removed before using the glassware in the experiment.
Another reason for conditioning is that any drops left in the glassware are from the intended solution and not water, that way the concentration will not change. However this is why washing thoroughly with soap and water would defeat the purpose of conditioning. It's possible to first wash with soap and water and then rinse with vinegar, but not viceversa.
Answer:
Zero (0)
Explanation:
Since Na^+ has a charge of +1 and Cl^- has a charge of —1 in NaCl
Then the net = +1 —1 = 0
