Answer:
Explanation:
Gilman reagent is also known as the Lithium organocuprates. They are used as nucleophiles in the organic synthesis.
Gilman reagent is used for C - C bond formation.

H H H H
(1 pentene)
Normally in C--C formation by Gilman reagent, the following reactions takes place :
R -- Br + R--R' + R' Cu + Li Br
In 1 pentene, i.e.
(from 1 bromo (from Gilman reagent)
propane)
So Gilman reagent is
Organo lithium compound is
Convert 10g of NaOH to moles using the molar mass.
10 g NaOH / 39.997 g/mol NaOH = 0.25 mol NaOH
NaOH is a strong base so it dissolves completely in solution, so you’ll have 0.25 mol of OH-. Calculate the molarity of OH-.
0.25 mol OH / 0.250 L = 1.0 M OH-
Calculate the pOH. pOH = -log(1.0) = 0
pH = 14 - pOH = 14
Explanation:
Let us assume that the ratio for the given reaction is 1:1.
Therefore, we will calculate the moles of as follows.
Moles of solution = molarity × volume (L)
= 0.0440 M × 0.014 L
= 0.000616 moles
Moles of excess EDTA = 0.000616 moles
Also, the initial moles of EDTA will be calculated as follows.
Total initial moles of EDTA = 0.0600 M × 0.025 L
= 0.0015
Therefore, moles of EDTA reacted with will be as follows.
= 0.0015 - 0.000616
= 0.00088 moles
Since, we have supposed a 1 : 1 ratio between and EDTA
.
So, moles of = 0.00088 moles
Now, we will calculate the molarity of as follows.
Molarity of solution =
=
= 0.015 M
Thus, we can conclude that the original concentration of the solution is 0.015 M.
Answer: C. Acts as energy reserve in muscle tissue.
Explanation:
Creatine Phosphate is a high energy compound that can be found in muscle tissue.
It serves as an extra energy storage, since the normal metabolism cannot supply the high energy requirement of a muscle at work.
Creatine Phosphate is quickly transfered to ADP, for the production of ATP needed for muscle contraction.
Answer:
D has to be based on facts so d would be the answer and idea that can only be proven true those are facts not hypothesis or guesses
Explanation:
based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world."
