Given :
The student looks up the value of the appendix of his textbook but cannot find a value for NaCl.
To Find :
Why the Ksp of NaCl is not present .
Solution :
Ksp values are given for those compounds which are partially soluble or insoluble in water .
But , we know NaCl is strong electrolyte and it completely dissociated in water .
So , the reaction go forward and their is no need to calculate Ksp .
Therefore , the Ksp of NaCl is not present .
Hence , this is the required solution .
Answer:
Mass of butane = 1.87 g
Explanation:
Form a balanced chemical equation for the reaction stated:
C₄H₁₀ + 13/2 O₂ → 4CO₂ + 5H₂O
Number of moles of CO₂
From the equation,
1 mol C₄H₁₀ : 4 mol CO₂
0.085 mol C₄H₁₀ : 0.34 mol CO₂
Mass of butane
