Which kind of molecule does the diagram represent?

Chemistry
1 answer:

Answer:

It is a triglyceride

Explanation:

A triglyceride is a molecule that contains a glycerol group and three fatty acids linked by an ester linkage. A fatty acid is a molecule formed by a long linear hydrocarbon chain, of different length or number of carbon atoms, at the end of which is a carboxyl group. These chains can be saturated (with hydrogen) or when there are double bonds in the chain  this reduces the available places of hydrogen that's why it's called unsaturated.

In the image you can see on the right the glycerol group. And the three fatty acids extending to the left. The top one is an example of a saturated fatty acid, and the two below unsaturated.

Triglycerides are generally solid at room temperature and are therefore called fats. For example, the fat that constitutes us is mostly formed by triglycerides.

A  substance can dissolve in another when they have thee same type of intermolecular interaction.

<h3>What is solubility?</h3>

The term solubility of a solute refers to the extent to which a solute dissolve in a solvent. We must know that a substance can dissolve in another when they have thee same type of intermolecular interaction.

Thus;

a) Octane (C8H18) mixes well with CCl4 because they are both non polar substances.

b) Methanol (CH3OH) is mixed with water in all ratios because the both are polar substances.

c) NaBr dissolves very poorly in acetone (CH3 ― CO ― CH3) because acetone is only slightly polar.

A 52.0-mL volume of 0.35 M CH3COOH (Ka=1.8×10−5) is titrated with 0.40 M NaOH. Calculate the pH after the addition of 23.0 mL of
Georgia [21]

NaOH reacts with CH3COOH in 1:1 molar ratio to produce CH3COONa 

NaOH + CH3COOH → CH3COONa + H2O 

Mol CH3COOH in 52.0mL of 0.35M solution = 52.0/1000*0.35 = 0.0182 mol CH3COOH 

Mol NaOH in 19.0mL of 0.40M solution = 19.0/1000*0.40 = 0.0076 mol NaOH 

These will react to produce 0.0076 mol CH3COONa and there will be 0.0182 - 0.0076 = 0.0106 mol CH3COOH remaining in solution unreacted . Total volume of solution = 52.0+19.0 = 71mL or 0.071L 

Molarity of CH3COOH = 0.0106/0.071 = 0.1493M 

CH3COONa = 0.0076 / 0.071 = 0.1070M 

pKa acetic acid = - log Ka = -log 1.8*10^-5 = 4.74. 

pH using Henderson - Hasselbalch equation: 

pH = pKa + log ([salt]/[acid]) 

pH = 4.74 + log ( 0.1070/0.1493) 

pH = 4.74 + log 0.717 

pH = 4.74 + (-0.14) 

pH = 4.60.

THE CONSTANT MOVING OF AND HELP THE TEMPERATURES AROUND THE EARTH REMAIN ABOUT THE SAME AVERAGE
nika2105 [10]

New analysis through 2014 shows that temperature is once again rising at about the same pace as it did over the second half of the 20 th century. PRESS RELEASE. Using the data that were available at the time (through 2012), the last climate report from the Intergovernmental Panel on Climate Change concluded that there had been no statistically significant increase in global surface temperature
