Answer:
Hydrosulfuric acid will act as limiting reactant.
Explanation:
Given data:
Mass of iron(III) chloride = 3243.0 g
Mass of hydrosulfuric acid = 511.8 g
Limiting reactant = ?
Solution:
Chemical equation:
2FeCl₃ + 3H₂S → Fe₂S₃ + 6HCl
Number of moles of iron(III) chloride:
Number of moles = mass/molar mass
Number of moles = 3243.0 g/ 162.2 g/mol
Number of moles = 20 mol
Number of moles of hydrosulfuric acid:
Number of moles = mass/molar mass
Number of moles = 511.8 g/ 34.1 g/mol
Number of moles = 15 mol
Now we will compare the moles of both reactant with products
FeCl₃ : Fe₂S₃
2 : 1
20 : 1/2 ×20 = 10
FeCl₃ : HCl
2 : 6
20 : 6/2 ×20 = 60
H₂S : Fe₂S₃
3 : 1
15 : 1/3 ×15 = 5
H₂S : HCl
3 : 6
15 : 6/3 ×15 = 30
Hydrosulfuric acid producing less number of moles of product thus, it will act as limiting reactant.
Answer:
i am thinking that they will be extinct
Explanation:
if their habitat is dying then they are dying and it would be sad
Work is done when the application of a force causes movement of an object in the direction of the force.
If there is no movement of the object or the object does not move in the direction of the force then work is not done.
Answer:
Initial temperature of the gas cylinder was 167.7K
Explanation:
Based on Gay-Lussac's law, the pressure of a gas under constant volume is directly proportional to its absolute temperature. The equation is:
P1*T2 = P2*T1
<em>Where P is pressure and T absolute temperature of 1, initial state and 2, final state of the gas.</em>
<em />
Replacing:
P1 = 1.25atm
T2 = 354.2K
P2 = 2.64atm
T1 = ?
1.25atm*354.2K = 2.64atm*T1
167.7K = T1
<h3>Initial temperature of the gas cylinder was 167.7K</h3>
<span>B) Boiling point Elevation states a solution typically has a measurably higher than a pure solvent . So would be B. </span>
