Answer:
Atorvastatin has two chiral centers. The question doesn't include the box where have to answer but I can show you in an image where are located and their configuration.
Explanation:
The first image shows the chemical structure of atorvastatin and their chiral centers identified as 1 and 2 respectively.
The second image shows the Fischer projections corresponding to every chiral carbon 1 and 2. I wrote R so suggest that there are more carbon atoms forward but not only corresponds to carbon atoms.
You can see that the chiral carbon 1 has R configuration due to the direction from the main substituent to the second follow the clockwise.
The chiral carbon 2 has S configuration due to the direction from the main substituent to the second one go anticlockwise.
Answer: The concentration of excess in solution is 0.017 M.
Explanation:
1.
moles of
1 mole of give = 1 mole of
Thus 0.019 moles of give = 0.019 mole of
2. moles of
According to stoichiometry:
1 mole of gives = 2 moles of
Thus 0.012 moles of give =
moles of
As 1 mole of neutralize 1 mole of
0.019 mole of will neutralize 0.019 mole of
Thus (0.024-0.019)= 0.005 moles of will be left.
Thus molarity of in solution is 0.017 M.
Answer : The grams of consumed is, 89.6 grams.
Solution : Given,
Mass of = 265 g
Molar mass of = 80 g/mole
Molar mass of = 28 g/mole
First we have to calculate the moles of .
The given balanced reaction is,
from the reaction, we conclude that
As, 1 mole of produces from 1 mole of
So, 3.2 moles of produces from 3.2 moles of
Now we have to calculate the mass of
Therefore, the grams of consumed is, 89.6 grams.
Answer:The formulas of ionic compounds are:
a)
b)
c)
d)
Explanation:
Formulas for the an ionic compounds is determine by:
Criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.
(a) Copper bromide :Given that it contains ion.
(b) Manganese oxide : Given that it contains ion.
(c)Mercury iodide :Given that it contains
(d) Magnesium phosphate :Given that it contains
Answer:
The final pressure is approximately 0.78 atm
Explanation:
The original temperature of the gas, T₁ = 263.0 K
The final temperature of the gas, T₂ = 298.0 K
The original volume of the gas, V₁ = 24.0 liters
The final volume of the gas, V₂ = 35.0 liters
The original pressure of the gas, P₁ = 1.00 atm
Let P₂ represent the final pressure, we get;
∴ The final pressure P₂ ≈ 0.78 atm.
