Ionization energy is a measure of the ability of atoms to attract electrons within a bond. True False

Xelga [282]

Answer:

The correct option is False

Explanation:

Ionization energy is the <em>minimum amount of energy required to remove a valence electron from one mole of an atom in it's gaseous state</em>. Ionization energy requires the removal of an electron from a gaseous atom. The definition in the question is that of electronegativity.

Electronegativity is the <u>ability of an atom to attract electrons towards itself in a chemical bond.</u>

Draw the 2 resonance structures of Malachite Green, and indicate which one is the equivalent contributor, and which one is the m

Yuri [45]

The two structures at the right of the image are the greatest contributors to the resonance structure of malachite green.

<h3>What is resonance structure?</h3>

In some cases, one single structure is insufficient to explain the properties of a substance. Now, we know that in such cases we have to invoke more than one structure in order to efficiently discuss the chemistry of the compounds in question.

In this case, we can see from the image that the three structures of malachite green are all resonance structures. However, the two structures at the right hand side are the greatest contributors because they are more conjugated. Hence, the two structures at the right of the image are the greatest contributors to the resonance structure of malachite green.

How many mL of 4.0% Mg(NO3)2 solution would contain 1.2 g of magnesium nitrate?

galina1969 [7]

4.0 % in mass per volume :

4.0 g ---------- 100 mL
1.2 g ---------- ( volume )

Volume = 1.2 x 100 / 4.0

Volume = 120 / 4.0

= 30 mL

hope this helps!
