Answer:

Yes this works.

Explanation:

This works because when the sugar is crushed, more of the surface area of the sugar gets exposed to the solvent, allowing the solvent to dissolve it a lot quicker than when it wasn't crushed.

Stirring also helps the sugar particles dissolve faster. This is because the particles are now agitated, which increases their kinetic energy.  This increase in Kinetic energy is reflected by increase in temperature, which helps the particles dissolve faster.

Answer: yes it does work.

Explanation:

When the sugar is crushed by the student, an increase in the number of molecules of sugar occurs. Meaning that more number of the solute (sugar molecules) are able to interact with the solvent (the water).

Therefore, there will be more number of collisions taking place between the solute and solvent molecules.

Hence, we can say it works because this leads to more interaction or collisions between the solute and solvent particles, as a result of this increased interaction between solute and the solvent, sugar will dissolve readily into the water.

A 25 kg rock is placed in a graduated cylinder with water.the volume of the fluid is 18.3ml.calculate the density of the rock in
ipn [44]

Answer:

=> 1366.120 g/mL.

Explanation:

To determine the formula to use in solving such a problem, you have to consider what you have been given.

We have;

mass (m)     = 25 Kg

Volume (v) = 18.3 mL.

From our question, we are to determine the density (rho) of the rock.

The formula:

p = \frac{m}{v}

First let's convert 25 Kg to g;

1 Kg    = 1000 g

25 Kg = ?

= \frac{25 × 1000}{1}

= 25000 g

Substitute the values into the formula:

p =  \frac{25000 g}{18.3 ml}

= 1366.120 g/mL.

Therefore, the density (rho) of the rock is  1366.120 g/mL.

10. Isolation of a pure sample of the third product, which has been determined to be an isomer of the major and minor products,
Ymorist [56]

Answer:

Four possible isomers (1–4) for the natural product essramycin. The structure of compound 1 was attributed to essramycin by 1H NMR, 13C NMR, HMBC, HRMS, and IR experiments.

Explanation:

Three synthetic routes were used to prepare all four compounds (Figure 2A). All three reactions utilize 2-(5-amino-4H-1,2,4-triazol-3-yl)-1-phenylethanone (5) as the precursor, whereas each uses different esters (6–8) to construct the pyrimidinone ring. Isomer 1 was prepared by reaction A, which used triazole 5 and ethyl acetoacetate (6) in acetic acid. This was the reaction used in syntheses of essramycin by the Cooper and Moody laboratories.3,4 Reaction B produced compound 2 (minor product) and compound 3 (major product), which were separated chromatographically. This reaction allowed reagent 5 to react with ethyl 3-ethoxy-2-butenoate (7) in the presence of sodium in methanol, under reflux for 24 h. Compound 4 was prepared by reaction C, which was obtained by reflux of 5 and methyl 2-butynoate (8) in n-butanol.
