Answer:
2 : 2
Explanation:
The balanced chemical equation is given as:
2K + Cl₂ → 2KCl
From the balanced reaction equation, we can conclude that;
- 2 moles of K will react with 1 mole of Cl₂
- 2 moles of K will produce 2 moles of KCl
- 1 mole of Cl₂ will produce 2 moles of KCl
Therefore, the mole ratio is 2:2 or 1:1 in the simplest form.
A poor ratio of Oxygen will cause incomplete combustion and the consequent deposit of carbon.
The balanced equation for the reaction is as follows;
Li₂O + H₂O ---> 2LiOH
Stoichiometry of Li₂O to H₂O is 1:1
Mass of Li₂O reacted - 18.9 g
Number of Li₂O moles reacted - 18.9 g / 30 g/mol = 0.63 mol
An equivalent amount of moles of water have reacted - 0.63 mol
mass of water required - 0.63 mol x 18 g/mol = 11.34 g
A mass of 11.34 g of water is required
<span>Mr = 13 g / mol
mass = 5 g
Mol = 5/13 mol :)</span>
