Abiotic
is the answer for you
Balanced chemical reaction: 2S + 3O₂ → 2SO₃.
1) Answer is: oxygen is limiting reactant.
n(S) = 3 mol; amount of sulfur.
n(O₂) = 4 mol; amount of oxygen.
From balanced chemical reaction: n(S) : n(O₂) = 2 : 3.
3 mol : n(O₂) = 2 : 3.
n(O₂) = (3 · 3 mol) ÷ 2.
n(O₂) = 4.5 mol; limiting reactant, because there is only 4 mol of oxygen.
2) Answer is: sulfur(S) is limiting reactant.
n(S) = 3 mol.
n(O₂) = 5 mol.
From balanced chemical reaction: n(S) : n(O₂) = 2 : 3.
n(S) : 5 mol = 2 : 3.
n(S) = 10 mol ÷ 3.
n(S) = 3.33 mol; there is only 3 mol of sulfur, so it is not enough.
3) Answer is: oxygen (O₂) is limiting reactant.
n(S) = 3 mol.
n(O₂) = 3 mol.
From balanced chemical reaction: n(S) : n(O₂) = 2 : 3.
3 mol : n(O₂) = 2 : 3.
n(O₂) = (3 · 3 mol) ÷ 2.
n(O₂) = 4.5 mol; limiting reactant, because there is only 3 mol of oxygen.
Answer : The mass of
precipitate produced will be, 9.681 grams.
Explanation : Given,
Molarity of NaI = 0.210 M
Volume of solution = 0.2 L
Molar mass of
= 461.01 g/mole
First we have to calculate the moles of
.
Now we have to calculate the moles of
.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 2 moles of
react to give 1 mole of
So, 0.042 moles of
react to give
moles of
Now we have to calculate the mass of
.
Therefore, the mass of
precipitate produced will be, 9.681 grams.
After series of conversion from one unit to another, the number of gallons was found to be 12 litres
<h3>
Density, Mass and Volume</h3>
Given Data
- Density of Sulfuric acid = 1.84 g/cm3
- Mass of Sulfuric acid = 184.33 Pounds
Conversion from pounds to Gram
1 kg ---------2.204 lb
x kg ---------184.33 lb
x = 184.33/2.204
x = 83.634 kg
hence the mass in gram = 83.634*1000
mass in gram = 83634 g
Now let us find the volume
We know that density = mass/volume
volume = mass/density
volume = 83634/1.84
volume = 45453.26 cm^3
Convert cm^3 to litres
Volume in litres = 45453.26 /1000
Volume in litres = 45.45 Litres
Convert from Litres to Gallons
1 gallon = 3.79 L
x gallons = 45.45 L
x = 45.45/3.79
x gallons = 11.99 L
Approx = 12 Litres
