<span>Which is an IUPAC name for a covalent compound?. . A. carbon dioxide</span>
Answer:
It is a Cline or layer where density gradient is greatest within a body of water
P = 1.5atm ≈ 1519.88hPa
V = 8.56L
R = 83.1 [hPa*L] / [mol*K]
T = 0°C =273K
pV = nRT |:RT
n = pV / RT
n = [1519.88hPa*8.56L] / [83.1 [hPa*L] / <span>[mol*K] * 273K]
n </span>≈ <u>0.57mol</u><span><u> </u></span>
Answer:
Solution B,
A concentrated solution is one that has a relatively large amount of dissolved solute. A dilute solution is one that has a relatively small amount of dissolved solute. However, these terms are relative, and we need to be able to express concentration in a more exact, quantitative manner.
<h3>
Answer:</h3>
Higher or lower pH affect the structure of the enzyme and reduces the enzyme activity.
<h3>
Explanation:</h3>
- Enzymes are biological molecules that speed up the rate of chemical reactions.
- Enzyme activity is affected by several factors which include temperature, pH, and enzyme inhibitors.
- Enzymes work on specific molecules known as substrates. They are substrate-specific.
- Enzymes work best at optimum pH and temperature.
- Higher or lower pH affects the structure and charges of an enzyme thus affecting enzyme activity.
- Lower temperature deactivates the enzymes while higher temperatures denature the enzymes.
