Explanation:
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 calorimeter = Joules
C = heat capacity of calorimeter = ?
Initial temperature of the calorimeter = = 22.37°C
Final temperature of the calorimeter = = 24.68°C
Change in temperature ,
Putting in the values, we get:
The heat capacity of the calorimeter is
Answer:
Explanation:
Let consider that one mole of diatomic oxygen is used. So, the stoichometric can be modelled by using three variables:
Where are the required variables.
Now, three equations are constructed from the number of elements involved (Carbon, Hydrogen and Oxygen):
Carbon
Oxygen
Hydrogen
The coefficients can be found by solving the abovementioned 3 x 3 Linear System:
The whole-number coefficients are determined by multiplying every coefficient by 3, then:
Molecules of SO₃ : 4.214 x 10²³
<h3>Further explanation </h3>The reaction equation is the chemical formula of reagents and product substances
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products
Reaction(balanced)
2SO₂(g) + O₂(g) → 2SO₃(g)
mol SO₃ :
number of molecules :
1 mol = 6.02 x 10²³ particles(atoms, molecules,ions)
