The balanced equation will tell you that.
C4H10 + O2 ===> CO2 + H2O
C4H10 + 6.5 O2 ===> 4CO2 + 5H2O
The number of mols of CO2 is 4.
i mean it can be true and it cant at the same time. i mean medicine doesn't always work on a person. but it is said that medicine that is in powder form is more efficient.
but i believe its D or A
Answer:
The PH of the mixture is 4.74
Explanation:
The number of millimoles of acetic acid is calculated using the formula:
No of millimoles= Molarity * Volume( in ml)
= 0.25M * 30ml = 7.5 moles
Number of millimoles of KOH is calculated using:
Number of millimoles = Molarity * Volume ( in ml)
=0.05M * 75ml
= 3.75 moles
The PH of the solution is derived using:
pH = pKa + log [salt] / acid
= ![-log [ 1.8 * 10^5 ] + log [ 3.75 mmoles/ 3.75 mmoles]](https://tex.z-dn.net/?f=%20-log%20%5B%201.8%20%2A%2010%5E5%20%5D%20%2B%20log%20%5B%203.75%20mmoles%2F%203.75%20mmoles%5D%20)
=4.74
