The answer would be Theodore Schwann, Matthias Jakob Schleiden and Rudolf Virchow(he contributed but is not credited)
Hope this helps
Have a great day/night
The correct answer is e. 3.57×10³
Al³+(aq) + 3e→AL(s)
4.00g of AL=4g/26.98 g/mol= 0.1483 mol
t=znF/1 where t is time in seceonds.
Z= valency number of ions of the substance or electrons which are transferred per ion
F= Faraday's constant
I = electric current in'A'CA C/s
t=(3×0.1483 mol ×96485 C/mol) /12(C15)
t=3577 second = 3.5 ×10³s
Answer:
Nutation
Explanation:
The counterclockwise rotation of planet earth around its own axis is defined as the Earth Rotation. The earth rotates about the line called "the axis of rotation," it is an imaginary line that passes through the North and South Poles of the planet, which the earth rotates about.
Hence, earth rotates once in about 24 hours with respect to the Sun, from West to East and thus giving rise to;
a. Day and night
b. Seasons
The Earth motion which describes the wobbling of the Earth around its precessional axis and could alter the amount of seasonal effects is known as nutation.
Basically, nutation usually occurs when the precessional motion of a planetary body such as planet earth experience some form of irregularities when it is rotating.
