Plant’s roots can take up water by capillary action.
Answer:
5.2 moles of KClO₃ are needed
Explanation:
Given data:
Number of moles of potassium chlorate needed = ?
Number of moles of O₂ formed = 7.8 mol
Solution:
Chemical equation:
2KClO₃ → 2KCl + 3O₂
now we will compare the moles of KClO₃ and O₂.
O₂ : KClO₃
3 : 2
7.8 : 2/3×7.8 = 5.2
5.2 moles of KClO₃ are needed.
4HBr(aq) + O2(g)= 2H2O(l) + 2Br2(l)
1pa=1N/m^2
1atm=760mmHg
1mmHg=1torr
1atm=101.325pa
