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.
Answer:
45200J
Explanation:
Given parameters:
Heat of vaporization of water = 2260J/g
Mass of steam = 20g
Temperature = 100°C
Unknown:
Energy released during the condensation = ?
Solution:
This change is a phase change and there is no change in temperature
To find the amount of heat released;
H = mL
m is the mass
L is the latent heat of vaporization
Insert the parameters and solve;
H = 20g x 2260J/g
H = 45200J
Slightly red in color is the only physical property
Answer:
pOH = 8.41
Explanation:
From the question given above, we obtained the following information:
Concentration of Hydrogen ion [H⁺] = 2.6×10¯⁶ M
pOH =?
Next, we shall determine the pH of the solution. This can be obtained as follow:
Concentration of Hydrogen ion [H⁺] = 2.6×10¯⁶ M
pH =?
pH = – Log [H⁺]
pH = – Log (2.6×10¯⁶)
pH = 5.59
Finally, we shall determine the pOH of the solution. This can be obtained as follow:
pH = 5.59
pOH =?
pH + pOH = 14
5.59 + pOH = 14
Collect like terms
pOH = 14 – 5.59
pOH = 8.41
Therefore, the pOH of the solution is 8.41
<h3><u>Answer;</u></h3>
+2
<h3><u>Explanation</u>;</h3>
- The electron configuration ofthe atom is 1s2 2s2 2p6 3s2. Upon forming an ion, its new configuration is 1s2 2s2 2p6.
- The atom has lost two electrons to form an ion which is positively charged with a charge of +2.
- In the given electronic configuration of an atom, '3s' shell is the outermost shell in which two electrons are present. For the stable configuration, these two electrons will be lost easily from the outer shell and atom will carry (+2).
- The atom has 12 electrons, and looses 2 electrons to attain stable configuration forming a positively charged ion with 10 electrons.
