Answer: The temperature rise is
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed by ice = 5280 J
m = mass of ice = 2.40 kg = 2400 g (1kg=1000g)
c = heat capacity of water =
Initial temperature =
Final temperature =
Change in temperature ,
Putting in the values, we get:
Thus the temperature rise is
We must use the Nernst equation
Step 1. Calculate E°
SO₄²⁻(aq) + 4H⁺(aq) + 2e⁻ ⇌ SO₂(g) + 2H₂O(ℓ)
<u>2Br⁻⇌ Br₂(aq) + 2e⁻ </u>
SO₄²⁻(aq) + 4H⁺(aq) + 2Br⁻(aq) ⇌ Br₂(aq) + SO₂(g) + 2H₂O(ℓ)
E° = 0.17 - 1.0873 = -0.92 V
Step 2. Calculate Q
E = 0 V
E° = -0.92 V
R = 8.314 J·K⁻¹mol⁻¹
T = 66 °C
n = 2
F = 96 485 C/mol
T = 66.0 + 273.15 = 339.15 K
It is the distance traveled by body with respect to time .
Its formula is Speed = distance /time
units : m/sec or Km/hr
It is total path traveled by body in any direction .
It unit and symbol is : S and unit = m /Km
It is the total distance traveled by body with respect to total time taken to travel that given distance .
Average speed = total distance /total time
A.s = T.D/T.T
unit = m/sec or Km/hr
It is the distance traveled by body at particular instant of time ,in given direction .
It is the shortest path traveled by body in given direction .
6 moles of ZnSO₄ produces 6 moles of Ag₂SO₄ .
Moles of ZnSO₄ = 6.00 mol
Moles of Ag₂SO₄ = ?
2Ag + ZnSO₄ → Ag₂SO₄ + Zn
Now we will compare the moles of ZnSO₄ and Ag₂SO₄.
ZnSO₄ : Ag₂SO₄
1 : 1
6.00 : 6.00
So 6 moles of ZnSO₄ produces 6 moles of Ag₂SO₄ .
