Answer:
The balanced half-reaction in which dichromate ion is reduced to chromium metal is a six-electron process.
Explanation:
The dichromate ion (Cr2O72-) has an oxidation state of +6, while chromium metal has an oxidation state of 0. So, 6 electrons must be transferred from the dichromate ion to chromium metal for the reduction to occur.
Answer:
equation gives the position at a specific time for an object with constant acceleration
Explanation:
equation gives the position at specific time for an object having constant acceleration. Constant acceleration is referred as the change of velocity with respect to the time is known as the acceleration, but when the velocity changes occurs at constant rate this rate is termed as the constant acceleration. The constant acceleration can never be zero. The velocity changes but that change occurs in the consistently. The acceleration is affected by the mass.
B. transverse
C. longitudinal
D. mechanical
