Answer:
The number of moles of CH₄ that will remain is 7.5 moles
Explanation:
Complete combustion reaction of oxygen and methane is given as;
CH₄ + 2O₂ → CO₂ + 2H₂O
comparing the number of moles of methane and oxygen in the reaction above, the amount of methane used in the reaction is calculated as follows;
2 moles of O₂ -----------> 1 mole of CH₄
7 moles of O₂ ------------> x moles of CH₄
x = 7 / 2
x = 3.5 moles of CH₄
Total moles of CH₄ in the reactor = 11.0 moles
The number of moles that will remain = 11.0 moles - 3.5 moles
The number of moles that will remain = 7.5 moles
Therefore, the number of moles of CH₄ that will remain is 7.5 moles
Answer:
Explanation:
a) 4-nitrobenzoic acid pKa= 3.41
benzoic acid pKa= 4.19
4-chlorobenzoic acid pKa= 3.98
b) benzoic acid pKa= 4.19
cyclohexanol pKa= 18.0
phenol pKa= 9.95
c) 4-Nitrobenzoic acid pKa= 3.41
4-nitrophenol pKa= 7.15
4-nitrophenylacetic acid pKa= 3.85
Answer:
Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered: the sand stays behind in the filter paper (it becomes the residue ) the water passes through the filter paper (it becomes the filtrate )
