Answer:
Explanation:
Hello!
In this case, since the undergoing chemical reaction is:
It is widely known that when a gas given off from a reaction is collected over water, we can compute its pressure by minusing the total pressure 762 mmHg and the vapor pressure of water at the experiment's temperature (20 °C) in this case 17.5 mmHg as shown below:
Next, by using the ideal gas equation we compute the yielded moles of oxygen considering the collected 313 mL (0.313 L):
Now, via the 3/2:1 mole ratio between oxygen and lithium chlorate (molar mass = 90.39 g/mol), we compute the original mass of decomposed lithium chlorate as follows:
Now, the percentage is computed as shown below:
Best regards!
Answer: The amino acid sequence is Leu-Ser-Val
Explanation: To produce amino acids, the DNA has to "transform" itself into a RNA by a process called Transcription. In this process, part of the DNA is transcribed into a similar RNA. The RNA produced undergoes another process, called Translation. From it, the sequence is decoded to a specific polypetide, as shown in this case. In the Translation, each 3 bases corresnpond to 1 amino acid. Because of it, the sequence above has 3 amino acids.
The N-terminal and C-terminal relates to the part where the sequence start to be read and the end of the process. Normally, the sequence starts at the 5', which correspond to the N-terminal and finishes at the 3', which matches the C-terminal. So in this example, the DNA template read 5\'GACAGACAA 3\'.
Answer:
5000 mL
Explanation:
Given data:
Volume in mL of solution = ?
Molarity of solution = 0.500 M
Number of moles of sugar = 2.5 mol
Solution:
Molarity = number of moles of solute/ volume of solution L
Now we will put the values.
0.500 M = 2.5 mol / Volume in L
Volume in L = 2.5 mol / 0.500 M
Volume in L = 5 L (M = mol/L)
Volume in mL.
5 L × 1000 mL / 1 L
5000 mL
Answer:
C
Explanation:
All others include a chemical change of some sort
Solution :
We know, pH of this solution :
Hence, this is the required solution.
