Answer:
ρ = 1469 kg/m³
Explanation:
given,
mass of statue = 0.4 Kg
density of statue = 8 x 10³ kg/m³
tension in the string = 3.2 N
density of the fluid = ?
Volume of the statue
V = 5 x 10⁻⁵ m³
W = ρ g V
W = ρ x 9.8 x 5 x 10⁻⁵
now, tension on the string will be equal to
T = mg - W
3.2 = 0.4 x 9.8 - ρ x 9.8 x 5 x 10⁻⁵
ρ x 9.8 x 5 x 10⁻⁵ = 0.72
ρ = 1469 kg/m³
Answer:
a) CI^- ⇒ CI2 + 2e^-
b) 4.2 * 10^9 amperes
c) 1.4 * 10^10 watts
Explanation:
Given data:
Annual production of C12 = 45 millions tons per year
Typical plant operational percentage = 90%
Operating voltage of a cell = 3.4 v
A) Half-cell reaction for oxidation chloride to form chlorine
CI^- ⇒ CI2 + 2e^-
B) Calculate the total current worldwide needed to generate the global supply of CI 2
Total current = =
= 4.2 * 10^9 amperes
Q = charge , t = time
C ) Calculate electrical power need to produce global supply of chlorine using electrolysis
P = V*I
= 3.4 * 4.2 * 10^9
= 1.4 * 10^10 watts
