What is safer to drink 113 ml of HCl or 244 ml of NaOH

A full bottle of water was left outside overnight in freezing temperatures, causing the bottle to crack. No mass was added or re

kodGreya [7K]

Answer:The correct answer is option C.

Explanation;

Water has unique property that is, it expands on freezing.Which is the reason for less density of ice than water. The cracking of the bottle was due to the expansion of water (present inside the bottle) on freezing.

Generally, density is inversely proportional to the volume of the substance.

$Density=\frac{Mass}{Volume}$

$Density\propto \frac{1}{Volume}$

As we know ,that water expands on freezing which means that volume increases. And with increase in volume of density decreases.

Hence, the correct answer is option C.

What bond vibrations and stretching frequencies should you observe in the IR spectrum of caffeine?

Margarita [4]

The bond vibrations that can be observed in the IR spectrum of caffeine :

i) asymmetric, ii) symmetric, iii) wagging, iv) twisting, v) scissoring, vi) rocking

while the observable stretching frequencies are ; 1700, 1300, 2900, 1500 and 3000.

Caffeine is a polyatomic molecule ( contains more than two atoms bonded via covalent bonds ) therefore its atoms can vibrate in three dimensions ( x, y, z ).therefore the bond vibrations that can be observed in the IR spectrum of caffeine are : asymmetric, symmetric, wagging, twisting, scissoring, and rocking.

The observable stretching frequencies that are in the IR spectrum of caffeine ; C = O is 1700 , C - H is 1300, C -H is 2900, C -N is 1500, and N -H = 3000.

Hence we can conclude The bond vibrations that can be observed in the IR spectrum of caffeine : i) asymmetric, ii) symmetric, iii) wagging, iv) twisting, v) scissoring, vi) rocking and the observable stretching frequencies are ; 1700, 1300, 2900, 1500 and 3000.

For neutral molecules, which statements about covalent lewis structures are true?

Zanzabum

Lewis structures have the distinct characteristic of electron dots drawn around an atom. They represent the valence electrons or the electron located at the outermost shell of the atom that takes part in chemical reactions.

For neutral compounds, they simply add the valence electrons of the individual atoms. This is because it has no charge. Whatever the net charge of the compound is, that would be added, as well.

For example, the HCl atom's valence electrons would be 1 + 7 + 0 = 8. Therefore, you draw 8 electron dots around the HCl compound.
