How does dissolving skittles apply to the real world?

Answers

Answer:

Skittles are coated with sugar and food coloring. When you add warm water to the Skittles, the sugar and food coloring start to dissolve. They have similar amounts coated on them so they dissolve at similar speeds and stay in their lanes.

 

The sugar is moving to areas of water with lower sugar concentration. If the water is poured in the center, this is happening for each Skittle at relatively the same speed.

the bradford assay only works at low protein concentrations

Answers

Answer:

Dilute the sample

Explanation:

The statement is not entirely accurate. The Bradford assay is commonly used to determine protein concentrations in a sample.

However, it is true that the Bradford assay is more accurate and reliable for measuring protein concentrations at low to moderate levels rather than at very high concentrations.

The Bradford assay is based on the binding of Coomassie Brilliant Blue dye to proteins. The dye undergoes a color change from brown to blue when bound to proteins, allowing for the measurement of protein concentrations. At low protein concentrations, the binding of the dye to proteins is well-calibrated and results in a linear relationship between protein concentration and color intensity, making it suitable for accurate quantification.

At high protein concentrations, the binding capacity of the dye may become saturated, leading to non-linear and less accurate measurements. The excess protein can also cause interference and affect color development. In such cases, dilution or alternative protein quantification methods may be more suitable, such as the BCA assay or the Lowry assay.

Therefore, while the Bradford assay can be used to measure protein concentrations across a range of concentrations, it is generally more reliable for low to moderate protein concentrations.

Calculate the mass of nitric acid required to make a 250mL solution with 2.40 ph

Please show steps, I am trying to learn!

Answers

The mass of nitric acid required to make the given solution is 0.0627 g.

The given parameters:

Volume of the acid, V = 250 mLpH of the acid, = 2.4

The hydrogen ion (H⁺) concentration of the nitric acid is calculated as follows;

[tex]H^+ = 10^{-pH}\\\\H^+ = 10^{-2.4}\\\\H^+ = 0.00398[/tex]

The molarity of the nitric acid is calculated as follows;

[tex]= 0.00398 \ H^+ \times \frac{1 \ M \ HNO_3}{1 \ H^+} \\\\= 0.00398 \ M[/tex]

The number of moles of the nitric acid is calculated as follows;

[tex]moles = M\times L\\\\moles = 0.00398\ M \ \times \ \frac{250 \ mL}{1000} \\\\moles = 9.95 \times 10^{-4} \ mol.[/tex]

The molar mass of nitric acid is calculated as;

[tex]HNO_3 = (1) \ + (14) \ + (16 \times 3) = 63 \ g/mol[/tex]

The mass of the nitric acid contained in the calculated number of moles is calculated as;

[tex]mass = moles\ \times \ molar \ mass\\\\mass = 9.95\times 10^{-4} \ mol. \ \times \ 63 \ g/mol\\\\mass = 0.0627 \ g[/tex]

Thus, the mass of nitric acid required to make the given solution is 0.0627 g.

A compound has a molar mass of 163.59 g/mol. If you have 736.155 grams of this compound, how many moles do you have?

Answers

Answer:

4.50000 moles

Explanation:

This is dimensional analysis. If there is 163.59 grams in 1 mole of this compound then the converse is true: in 1 mole of this compound there is 163.59 grams --> 1 mol/163.59 grams.

Now that you have your conversion factor:

736.155 grams * (1 mol/163.59 grams) is your equation.

When you multiply these together, grams cancel and you end up with the desired mole-based answer:

4.50000 moles (The extra zeros are to make up for the 6 significant figures in 736.155, feel free to omit them if necessary.)
