Answer:
0.17%
Explanation:
With the equation:
2Cr2O7 2- + C2H5OH + H2O --> 4Cr3+ + 2CO2 + 11H2O
We can assume that every mole of ethanol needs 2 moles of Dichromate to react.
So if in 1L we have 0.05961 moles of dichromate we can discover how many moles we have in 35.46mL
1000 mL - 0.05962 moles
35.46 mL - x
x = 
x = 2,11* 10^-3 moles
As we said earlier, 1 mole of ethanol needs 2 mole of dichromate, so in the solution we have 1,055*10^-3 moles of ethanol. We can discover the mass of ethanol present in the solution.
1 mole - 46g
1.055*10^-3 - y
y = 46 * 1.055*10^-3
y = 0.048 g
To discover the percent of alchol we can use a simple relation
28 g - 100%
0.048 - z
z = 
z = 0.17%
Answer
The answer is explained in the attachment.
There are 7 valence electrons in a Chlorine atom. A chlorine atom needs one more electron to have a complete octet.
Explanation:
The answer is explained in the attachment.
There are 7 valence electrons in a Chlorine atom. A chlorine atom needs one more electron to have a complete octet.
As we know that one mole contains 6.022 × 10²³ particles. And the number of particles are related to moles as,
# of Particles = Moles × 6.022 × 10²³ particles
In case of Zinc atoms,
# of Atoms = Moles × 6.022 × 10²³ Atoms/mol
Putting value of moles.
# of Atoms = 6.05 mol × 6.022 × 10²³ Atoms/mol
# of Atoms = 3.64 × 10²⁴ Atoms
Answer:
if the G stands for gallons and the ml stands for milliliters then the answer would be
Explanation:
4086/5445
we can convert the gallons to ml so its easier to divide
15,467,193/5445
2,840.623140495868
which if you need to as a whole number would be 2,841
