Explanation:
The pH of a solution can you be found by using the formula
Since we are finding the [H3O+] , substitute the value of the pH and find it's antilog
We have
Hope this helps you
Answer:
The excess reactant is the NaCl.
Explanation:
NaCl(aq) + AgNO3 (aq) → NaNO₃(aq) + AgCl (s) ↓
This is a precipitation reaction.
We need to convert the mass of each reactant to moles:
4 g / 58.45 g/mol = 0.068 moles of NaCl
10 g / 169.87 g/mol = 0.059 moles of nitrate.
As stoichiometry is 1 by 1, 1 mol of chloride will react with 1 mol of nitrate.
If I have 0.059 moles of nitrate, I will need the same amount of chloride and I have 0.068 moles. I still have chloride, therefore the excess reactant is the NaCl.
0.068 mol - 0.059 mol = 0.009 moles are the moles of NaCl that remains after the reaction is complete
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\'.
