Answer:
Explanation:
From the information given, we are to show the product of the reaction between the alcohol (stick formula) with pyridinium chlorochromate. The reaction starts with the nucleophilic addition of Cr with oxygen molecule on the alcohol. Then, deprotonation of oxygen occurs, this process is followed by the removal of hydrogen ion to yield the final product. The reaction mechanism can be seen from the attached image below.
Strong and good for you bro
A). Object A, because the shorter the distance between objects result in a stronger gravitational force
Answer:
pH = 10
Explanation:
KOH is a strong base; thus it will completely dissociate:
KOH -> K⁺ + OH⁻
Since it completely dissociates, the concentration of both K⁺ and OH⁻ will be the concentration of KOH given (1.0 x 10^-4 M).
We can then find pOH by taking the negative log of the OH⁻, or hydroxide, concentration:
pOH = -log[OH⁻] = -log[1.0 x 10^-4 M] = 4
At 25 degrees Celsius, pH + pOH = 14. If we solve for pH and then plug in our pOH, we get:
pH = 14 - pOH = 14 - 4 = 10
The pH of a 1.0 x 10^-4 M solution of KOH is thus 10.
