5C₂ + 4SO₂ ------> 2CS₂ + 8CO
mole ratio of C₂ : CS₂
= 5 : 2
∴ since C₂ contains 8 moles
then CS₂ contain
moles
= 3.2 moles
Answer:
option b is correct option = (6.76×10¹⁴ Hz)
Explanation:
Given data:
Wavelength of photon = 4.42×10⁻⁷ m
Speed of light = 2.99×10⁸ m/s
Frequency of radiation = ?
Solution:
Formula:
Speed of wave = frequency × wavelength
Now we will rearrange this formula.
frequency = Speed of wave / wavelength
f = c/ λ
f = 2.99×10⁸ m/s / 4.42×10⁻⁷ m
f = 0.676×10¹⁵ Hz (s⁻¹ = Hz)
f = 6.76×10¹⁴ Hz
Thus option b is correct option.
Answer:
Because of Hydrogen Bonding!
Answer:
Physical
Explanation:
Physical weathering is defined as the geological process in which rocks are broken down but there is no change in their chemical composition.
Granite tor are the rock masses above the ground surface which are associated with granites
Granite Tor is an example of physical weathering as they formed by freeze–thaw weathering. Granite tor are formed when magma present in the crust cools down and form batholith. Rocks above batholith gets erodes and left the batholith to expose.
Hence, the correct answer is "Physical weathering'.
Physical: abrasion, crystallization, insolation, melting and freezing.
Chemical: hydration, oxidation(rust), carbonic acid action, and hydrolysis
