Answer:
The volume of the liquid should be measured before it is heated.
Explanation:
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
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. :)
The resources that have been linked to producing carbon dioxide are coal and natural gas.
Global warming is caused by the emission of greenhouse gases. Carbon dioxide emissions are the most important cause of global warming. Carbon dioxide is created by the burning of fossil fuels, such as oil, natural gas, diesel, organic-diesel, petrol, ethanol among others. Carbon dioxide have been increasing within the last 50 years and are still increasing.
