I hope this helps
Explanation:
Aluminium - Al
Iron Sulfate - FeSO4
The reaction is given as;
Al + FeSO₄ --> Al₂ (SO₄) ₃ + Fe
The balanced equation is given as;
2 Al + 3 FeSO₄ --> Al₂ (SO₄) ₃ + 3 Fe
In words it is given as;
Aluminium + Iron Sulfate --> Aluminium Sulfate + Iron
The answer is a chlorine atom.
Answer:-
240.558 K
Explanation:-
Number of Moles n = 1
Pressure P = 20 kilopascals = 20 KPa
Volume V = 100 L
We know Universal Gas constant R = 8.314 L kPa K−1 mol−1
Using the relation
PV = nRT
Temperature T = P x V / ( n x R)
T = 20 KPa x 100 L / ( 1 mol x 8.314 L kPa K−1 mol−1 )
= 240.558 K
Answer:
We will collect 11.17 liters of oxygen gas.
Explanation:

Where:
N = Number of particles / atoms/ molecules
n = Number of moles
= Avogadro's number
We have:
Molecules of oxygen gas N = 
n =?

n = 0.4982 moles of oxygen
Using ideal gas equation:
PV = nRT
where,
P = Pressure of gas = 1 atm (at STP)
V = Volume of gas = 10 L
n = number of moles of gas = ?
R = Gas constant = 0.0821 L.atm/mol.K
T = Temperature of gas = 273.15 K (at STP)
Putting values in above equation, we get:

V = 11.17 L
We will collect 11.17 liters of oxygen gas.
