Answer:

Yes! It's because of like freezing and or solidification. It's the phase transition in which a liquid turns into a solid. It's when the temperature is lowered to or below a type of freezing point.

Define monosaccharide disaccharide and polysaccharide give at least two examples of each. which of these is the

Ainat [17]

Saccharides are carbohydrates, molecules containing Carbon (C), Hydrogen (H), and Oxygen (O). "Saccharo" means sugar in Greek. Also Greek, "mono" means one, "di" means two, and "poly" means many.
A sugar molecule is based upon a ring of carbons with H's and OH's attached. One sugar molecule alone is a monosacchararide, like glucose and fructose. Two sugar molecules bonded together covalently is a disaccharide, like lactose (milk sugar) and sucrose (table sugar). Many sugar molecules (upwards of hundreds or thousands) bonded together covalently is a polysaccharide. Examples are glycogen (animal starch) and cellulose (plant starch).

Lewis dot diagram for the Cs1+ ion

creativ13 [48]

Answer:

$Cs^+$

Explanation:

Cesium Lewis dot structure would look like this:

·Cs, because it only has one valence electron. But, since it has a plus, that means we lost an electron. So, we have to get rid of the dot and you have:

$Cs^+$

The mass spectrum of an unknown compound has a molecular ion peak with a relative intensity of 57.10% and an M+1 peak of 6.83%.

max2010maxim [7]

There are 11 Carbon atoms in the compound.

<u>Solution:</u>

Carbon atom count is the ratio of the M peak to the M+1 peak.

$\text{ Number of Carbon atoms }=\frac{\text { Relative intensity of } M+1 \text { peak }}{0.011 \times \text { Relative tntensity of } M \text { peak }}$

Here M peak is 57.10% and M+1 peak is 6.83%. On applying the values in the formula we get,

$\frac{0.0683}{0.011\times0.571g} = 10.87\approx11$

Therefore, the number of Carbon atoms in the compound are 11.

Refer the image attached below for a better understanding of M peak and M+1 peak.

The heaviest ion that has the greatest m/z value is said to be the molecular ion peak in mass spectrum.
