How does sugar dissolve in water

Chemistry
1 answer:
Ne4ueva [31]3 years ago
5 0

Answer:

Sugar dissolves in water because energy is given off when the slightly polar sucrose molecules form intermolecular bonds with the polar water molecules. The weak bonds that form between the solute and the solvent compensate for the energy needed to disrupt the structure of both the pure solute and the solvent.

Explanation:

The sugar cubes soften when placed in the water and begin to dissolve. The sugar cube in the hot water dissolves the fastest. Sugar will dissolve faster when you stir the solution quickly because the act of stirring increases kinetic energy which increases the temperature.

Determine the pH of a 0.530 M solution of carbonic acid that has an acid dissociation constant of 4.4 x
Veronika [31]

Answer:

Explanation:

H2CO3  =  H+   +  HCO3-   H2CO3  =  0.530 M  Ka =4.4 X10^-7

Ka =[H+][A-]/[HA]        [H+] = [A-]

0.530 M x 4.4 X10^-7=  [H+}^2

2.32 X10^-7  =  [H+}^2

23.2 X10^-8 = [H+}^2

4.83 X 10^-4 = [H+]

pH = - log 4.83 X 10^-4

pH = -(.68-4)

pH =-(-3.32)

pH= 3.32

Lena [83]

Answer:

a).

2 \: moles \: of \: ethane \: react \: with \: 7 \: moles \: of \: oxygen \\ 24 \: moles \: react \: with \: ( \frac{24 \times 7}{2} ) \: moles \\  = 84 \: moles

b).

2 \: moles \: react \: with \: 7 \: moles \\ ( \frac{12 \times 2}{7} ) \: moles \: react \: with \: 12 \: moles \\  = 3 .43 \: moles \\ 1 \: mole \: weighs \: 30 \: g \\ 3.43 \: moles \: weigh \: (3.43 \times 30) \\  = 102.9 \: g

The conversion of the fatty acid palmitate (c16) to carbon dioxide via β-oxidation, the citric acid cycle and oxidative phosphor
Semmy [17]

The conversion of the fatty acid palmitate (C-16) to carbon dioxide via β-oxidation, the citric acid cycle and oxidative phosphorylation yield approximately <u>106 atp</u> equivalents.

The most prevalent kind of fatty acid with sixteen carbon atoms without carbon-carbon double bonds would be palmitic acid. There must be a maximum of seven cycles of beta-oxidation in order to totally degrade the fatty acid. 8 acetyl-CoA molecules, 7 NADH molecules, with 7 FADH2 molecules are produced as a result of this.

The primary enzyme, CAT-1, catalyzes the production of acylcarnitine carnitine, which provides the rate-limiting step in beta-oxidation.

Therefore, the conversion of the fatty acid palmitate (C-16) to carbon dioxide via β-oxidation, the citric acid cycle and oxidative phosphorylation yield approximately <u>106 atp</u> equivalents.
