The condensation point of water is the same as its boiling point. This means that it is 100°C (212°F). Hope that helps!
Answer:
Volume of water
Initial temperature of the solution
Final temperature of the solution
Mass of NH₄Cl
Explanation:
There are two heat transfers involved in this experiment.
Heat of solution of NH₄Cl + heat lost by water = 0
q₁ + q₂ = 0
nΔH + mCΔT = 0
nΔH = -mCΔT
ΔH = -mCΔT/n
So, you must measure
- the volume of water (you will probably use its density to calculate its mass)
- the initial and final temperatures of the solution (to calculate ΔT)
- the mass of NH₄Cl (to calculate the number of moles)
You will probably assume that the specific heat capacity of the solution is the same as that of water, so you won't be measuring it.
First we will calculate the number of moles of Iron:
, where n is the number of moles, m is the mass of iron in the reaction and M is the Atomic weight.
moles of Iron.
The same number of moles of Oxygen will take part in the reaction.
So
where 32 is the Atomical Weight of Oxygen (16 x 2).
