Answer:
multiply the first equation by 3 to cancel the electrons in both equations
then combine both equations
then minus both cell potentials which equals 0.78 V
I'm not sure though
Answer:
See explanation
Explanation:
The major difference between distance and displacement is that distance is a scalar quantity while displacement is a vector quantity. Scalar quantities have magnitude without direction while vector quantities have both magnitude and direction.
The distance covered by Benjamina in both cases just refer to the difference in her position at each time without reference to the direction in which she changed her position.
Her displacement will clearly mention the direction in which she moved both when she walked to the front door of her apartment and when she walked to a friend's apartment.
Answer:
Mole fraction O₂ = 452 mmHg/ 780mmHg → 0.579
Explanation:
Mole fraction is defined as the quotient between Partial Pressure of a gas, in a mixture and the Total Pressure from the mixture
Partial pressure of a gas/ Total pressure
Mole fraction O₂ = 452 mmHg/ 780mmHg → 0.579
Be careful, because mole fraction doesn't have units
