<u>Answer:</u> The balanced chemical equation is written below.
<u>Explanation:</u>
Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This also means that total number of individual atoms on reactant side must be equal to the total number of individual atoms on the product side.
A balanced chemical equation always follows this law.
For the given chemical reaction, the balanced equation follows:
This is considered as neutralization reaction because an acid reacts with a base to produce a salt and water.
Hence, the balanced chemical equation is written above.
Answer:
Perfectly Specified
Explanation:
Given,
Pressure = P = 0.9 atm
and the Boiling point = T
Number of phases P = 1
Number of components C = 1
According to Gibb's phase rule ,
F = C - P + 2
If
- F = 0, the system is perfectly specified
- F > 0, the system is under specified
- F < 0 the system is over specified
At P = 0.9 atm, boiling point is T i.e. Fixed equal to 96.7 °C (from steam table)
P is independent variable and T is dependent variable (depends on the value of P ).
In this case only two variables are required to fix the system pressure and temperature.
In the given problem, pressure is fixed so the temperature is also fixed. There is no requirement of any other variable.
Therefore degree of freedom,
F = 0
The system is perfectly specified.
Answer:
29. Proteins support the body's structural framework, chemical reactions, and contractions (muscle movement).
30. Proteins have a primary structure (polypeptide chain of amino acids), secondary structure (made up of alpha helices and beta pleat sheets), tertiary structure (superimposed on secondary structure), and quaternary structure (2 or more polypeptide chains with its own tertiary structure).
31. Protein molecules can denature if conditions aren't right, such as the wrong temperature or pH level. When denatured, proteins typically lose their shape and their function for a short time because their active sites become deactivated (though if conditions are too extreme, they can permanently lose their function). This happens to globular proteins because they are not nearly as stable as fibrous proteins due to their functional 3D shape.
I just did the first 3 since I could easily access the proteins section in my textbook at the moment. :)
