Answer:

Thermal decomposition

Explanation:

The thermal decomposition of amino acids could be carried out at different temperatures and at fixed pressure in a reactor. The effect of temperature on products and pathway could be determined by using time as a function. The hydrothermal decomposition of amino acids takes two key paths

1. The delamination of amino acids to produce ammonia and organi acids

2. The decarboxylation to produce amines and carbonic acids.

The thermal decomposition is and effective experiment that could determine the chemical reaction rate and order of reaction, since it's working with time.

Which reaction is capable of breaking polypeptides into their component amino acids?
Bad White [126]

Answer: B. Hydrolysis (adding water)

Explanation:

When peptide bonds join two or more amino acids together, this is refered to as a peptide. A polypeptide simply means several amino acids. We should also note that proteins contains polypeptides.

The reaction that is capable of breaking polypeptides into their component amino acids is hydrolysis. This simply means a chemical process whereby a water molecule is being added to a particular substance.

Given the density of iron (Fe) is 7.87 g/cm3, determine the mass of iron (in grams) in a rectangle block with the dimensions of
guapka [62]

Answer:

m=14,105.71 g Fe

Explanation:

Hello,

In this case, the first step is to compute the volume of the block considering the length, height and width:

V=L \times W \times H =12.5 in\times 3.50 in \times 2.50 in =109.375 in^3

Then, we compute the volume in cubic centimetres:

V=109.375in^3\times \frac{16.3871 cm^3}{1in^3} =1792.34cm^3

Finally, as the density is given by:

\rho =\frac{m}{V}

We solve for the mass:

m=\rho \times V= 7.87\frac{g}{cm^3} \times 1792.34 cm^3\\\\m=14,105.71 g Fe

Best regards.

What is the hydrogen ion concentration ([H']) of a substance with a pH of 4.91?
Ksenya-84 [330]

Answer:

The pH of a solution is a measure of the concentration of hydrogen ions in the solution. A solution with a high number of hydrogen ions is acidic and has a low pH value. A solution with a high number of hydroxide ions is basic and has a high pH value. The pH scale ranges from 0 to 14, with a pH of 7 being neutral.
