Answer:
The answer should be A:) The energy produced from the splitting of atoms.
Explanation:
V₁ = <span>178 mL - initial volume
</span>T₁ = 0 ⁰C = 273K - initial temperature
V₂ = <span>211 mL - final volume
</span>T₂ =? - final temperature
According to Charles's law when pressure is constant the Kelvin temperature and the volume will be directly related:
V₁/T₁=V₂/T₂
178/273=211/T₂
0.65=211/T₂
T₂=324K= 51⁰C

Answer:
Moles of potassium chloride = 0.3 mol
Explanation:
Given data:
Number of moles of potassium chloride needed = ?
Mass of oxygen produced = 13 g
Solution:
Chemical equation:
2KClO₃ → 2KCl + 3O₂
Number of moles of oxygen:
Number of moles = mass/ molar mass
Number of moles = 13 g/ 32 g/mol
Number of moles = 0.41 mol
Now we will compare the moles of oxygen with potassium chloride.
O₂ : KCl
3 : 2
0.41 : 2/3×0.41 = 0.3
So number of moles of potassium chloride produced would be 0.3 moles.
Mass of potassium chloride:
Mass = number of moles × molar mass
Mass = 0.3 mol × 74.55 g/mol
Mass = 22.4 g
