Difference Between Empirical and Molecular Formulas. The key difference between empirical and molecular formulas is that an empirical formula only gives the simplest ratio of atoms whereas a molecular formula gives the exact number of each atom in a molecule. In chemistry, we often use symbols to identify elements and molecules.

Answer:
Explanation:
Nitrogen has a lone pair of electrons. That would mean that NH3 is minus at the left end in this case.

it will turn blue black to any substance
Answer:

Explanation:
Given
485 L
Required
Determine the measurement not equal to 485L

<em>From standard unit of conversion;</em>
1 KL = 1000 L
<em>Multiply both sides by 485</em>


<em>Divide both sides by 1000</em>

---- This is equivalent
---------------------------------------------------------------------------------------------

<em>From standard unit of conversion;</em>
1000 mL = 1 L
<em>Multiply both sides by 485</em>


Convert to standard form

Hence;
is not equivalent to 485L
---------------------------------------------------------------------------------------------

<em>From standard unit of conversion;</em>
100 cL = 1 L
<em>Multiply both sides by 485</em>


Convert to standard form
---- This is equivalent
---------------------------------------------------------------------------------------------
μL
<em>From standard unit of conversion;</em>
1000000 μL = 1 L
<em>Multiply both sides by 485</em>


Convert to standard form
---- This is equivalent
From the list of given options;
is not equivalent to 485L
