Answer:
Due to deficiency of Oxygen in atmosphere.
Explanation:
Oxidation is defined in two ways, 1) The addition of Oxygen and Removal of Hydrogen 2) The removal of electrons.
We will discuss the first definition for this question. The addition of oxygen to various compounds results in the oxidation of that compound.
Example: Oxidation of Methane;
CH₄ + 2 O₂ → CO₂ + 2 H₂O
In this example oxygen is added to methane and hydrogen is being removed from methane.
Oxidation type chemical weathering common more than 2 billion years ago because of less amount of Oxygen in atmosphere and the oxygen which was produced by plants reacted with different metals like Iron forming precipitates which precipitated to the bottom of oceans.
Answer:
K=1.61×10−19 J
Explanation:
In the question data given is as follows:
Wavelength of the is given as light (λ)=233 nm
while the worrk-function of the titanium given as (ϕ)=6.93×10−19 J
but for the energy imparted due to the light will now be
E=hcλE, then
E=hcλE=(6.63×10−34)(3×108) / 233×10−9
E=8.536×10−19 J
Now, the energy imparted is given by
E= ϕ + K
8.536×10−19= (6.93×10−19) + K
K=1.61×10−19 J
Then,
K is the kinetic energy of the electrons
Answer:
The seven SI base units, which are comprised of:
Length - meter (m)
Time - second (s)
Amount of substance - mole (mole)
Electric current - ampere (A)
Temperature - kelvin (K)
Luminous intensity - candela (cd)
Mass - kilogram (kg)
