Answer:
As the temperature of a fixed volume of a gas increase the pressure will increase.
Explanation:
According to the Gay- Lussac's Law,
" The pressure of given amount of gas is directly proportional to the temperature at a constant volume"
Mathematical expression:
P ∝ T
P = CT
P / T = C
As the temperature increase, the pressure also increase.
The initial and final expression of volume and pressure can be written as,
P₁ / T₁ = P₂ / T₂
Answer:
I think it both physical & chemical change :')
<em><u>look at the clues by it and try not to trust the links they trying to give u...</u></em>

2KClO₃ → 2KCl + 3O₂
mole ratio of KClO₃ to O₂ is 2 : 3
∴ if moles of O₂ = 5 mol
then moles of KClO₃ =

= 3.33 mol
Mass of KClO₃ needed = mol of KClO₃ × molar mass of KClO₃
= 3.33 mol × ((39 × 1) + (35.5 × 1) + (16 × 3) g/mol
= 407.93 g
