Explanation:
ABC looks like the metamorphic rocks are more usable than other rocks
<span>Electron microscopes can magnify objects to 10,000,000x the smallest object that can be viewed is larger than an electron. Electron microscopes can improve the resolution that is achieved by light microscopes. Entire cells can be viewed and their components.</span>
Answer:
Wavelength = 64.635 pm
Explanation:
The expression for the deBroglie wavelength and kinetic energy is:
Where,
is the deBroglie wavelength
h is Plank's constant having value
m is the mass of electron having value
K.E. is the kinetic energy of the electron.
Given, K.E. = 360 eV
Energy in eV can be converted to energy in J as:
1 eV = 1.6022 × 10⁻¹⁹ J
So, K.E. = 
Applying in the equation as:

Also, 1 m = 10¹² pm
<u>So, Wavelength = 64.635 pm</u>
Answer:
C. II, III, IV, and V.
Explanation:
Acid buffer is generally formed by the combination of a weak acid as well as the salt of the conjugate base.
Basic buffer is formed the combination of a weak base and also the salt of the conjugate acid.
On dilution the ration of the concentration terms of the salt and weak acid/base does not change. Hence the pH of the buffer solution does not change.
When acid or base is added to buffer, it resists changes in the pH.
Therefore, option (C) is correct.
I believe it’s Amphoteric oxide
