<em><u>Given</u></em>
Weight of pottasium fluoride (KF) = 29 gms
<em><u>To find</u></em>
Number of moles of pottasium fluoride = ?
<em><u>Solution</u></em>
we know that molar mass of KF = 58.0967 g
Now,

<em>Number of moles = 29/58 = 0.5 moles</em>

Given equation:
P + O2 → P2O5
In order for the equation to be balanced, the stoichiometry of the atoms of one kind on the reactant side must be equal to that on the product
Reactants Products
P = 1 P = 2
O = 2 O = 5
The balanced equation would be:
4P + 5O2 → 2P2O5
Reactants Products
P = 4 P = 4
O = 10 O = 10
Ans: D)
Because the chemical composition of the plant itself hasnt changed at all
