1 is hours and 2 is meters
Answer:

Explanation:
The half-cell reduction potentials are
Ag⁺(aq) + e⁻ ⇌ Ag(s) E° = 0.7996 V
Fe²⁺(aq) + 2e⁻ ⇌ Fe(s) E° = -0.447 V
To create a spontaneous voltaic cell, we reverse the half-reaction with the more negative half-cell potential.
The anode is the electrode at which oxidation occurs.
The equation for the oxidation half-reaction is

Answer:
D. 4.75 m/s west
Explanation:
You can immediately get the answer once you know the formula for<em> velocity.</em>
- The formula for velocity is: Velocity (V) =

The distance is 95 meters while the time is 20 seconds. All you have to do is to divide <u>95 meters by 20 seconds</u>.
Let's solve:
- V =

- V =

- V = 4.75 meters per second
Since Brenda is going west with her her skateboard, then you have to add <em>west </em>as her direction.
Brenda's velocity is 4.75 m/s west.
Plum-pudding model is different from the model that came after it as the Plum pudding model did not encounter the concept of nucleus it simply says compares atom with a pudding in which electrons are spread around as rasins in a pudding while the model that came after that is Rutherford's model explain that the atom that having nucleus that serves as a center of the atom.
