DochEvi [55]
3% = 0.3
.03*540 = 16.2
540-16.2 = 523.8

Meaning 16.2 milliliters alcohol and 523.8 milliliters water. If my math is correct.

Add curved arrows to both resonance structures of nitromethane to show the delocalization of electron pairs. A curved arrow star
DaniilM [7]

Answer:

As it is possible to observe in the drawing of the resonance structure of nitromethane, both oxygen atoms have the same negative charge.

Explanation:

A resonance structure is the molecular bonding system in which a hybrid, called a resonance, is formed from two or more Lewis structures that have different electronic distributions.

The resonance effect is given by the delocalization of electrons, which are not at a fixed point but are distributed homogeneously in the molecule as we can see in the nitromethane, providing stability. So the more resonance structures the molecule has, the more stable it will be.
