Ga₂O₃ + 2NaOH + 3H₂O = 2Na[Ga(OH)₄]
[Ga(OH)]⁻ + 3e⁻ = Ga + 4OH⁻
n(Ga)=It/(zF)
I=0.200 A
t=40.0 min=2400 s
z=3
F=96485.33 Kl/mol
n(Ga)=0.200*2400/(3*96485.33)=0.00166 =1.66*10⁻³ mol
Chemical equivalent of an element is the value obtained by dividing the atomic weight of the given element by its valency. Electrochemical equivalent: Electrochemical equivalent on the other hand, refers to the mass of substance deposited when a current of 1 Ampere is passed for 1 Second during electrolysis. thats the answer when i first saw this i thought it was just one of thos free points with gibberish XD
According to the second law of thermodynamics, heat energy released by an organism is released into the <span>environment and unusable. This energy is also known as entropy which is defined as the tendency of things to be dispersed and spontaneous. This means that entropy is always random and becomes unavailable energy.</span>
Answer:
Newton's 2nd Law says the acceleration of an object depends on its <u>mass </u>and the amount of <u>net force</u> acting on it.
Explanation:
Definition of acceleration:
The acceleration is rate of change of velocity of an object with respect to time.
Formula:
a = Δv/Δt
a = acceleration
Δv = change in velocity
Δt = change in time
Units:
The unit of acceleration is m.s⁻².
Acceleration can also be determine through following formula,
F = m × a
a = F/m
This is the newton's second law:
"The acceleration of an object depends on its <u>mass </u>and the amount of <u>net force</u> acting on it"
The acceleration is depend directly on the force while inversely on the mass.
