actor Atoms Molecules
Definition Most fundamental and smallest part that can exist of an element. Two or more atoms chemically bonded together.
Example Oxygen – O
Phosphorus – P
Sulphur – S
Hydrogen – H Oxygen – O2
Phosphorus – P4
Sulphur – S8
Water – H2O
Structure The smallest particle with properties of an element. Combination of two or more atoms.
Stability An atom may not always be stable in nature due to the presence of electrons in the outer shells. Molecules are formed to attain stability.
Constituent Elements Protons, Electrons & Neutrons Two or more atoms of the same or different elements
Reactivity Except for the noble elements, atoms of all elements showcase a certain level of reactivity. Compared to a molecule, the level of reactivity is less than some valence points are filled by electrons of combined elements.
Answer:
Given equation of parabola is
and
2
=64x ......(i)
The point at which the tangent to the curve is parallel to the line is the nearest point on the curve.
On differentiating both sides of equation (i), we get
2 y
dx
d y
=64
⇒
dx
d y
=
and
32
Also, slope of the given line is −

4
∴−

⇒and=−24
From equation (i), (−24)
2
=64x⇒x=9
∴ the required point is (9,−24)

Hello,
In this case, we can use the Avogadro's law in order to understand the mole-volume behavior as a directly proportional relationship:
Nonetheless, here we are not given neither the identity of the gas nor its molar or atomic mass, for that reason we can apply the aforementioned equation in terms of mass as we are talking about the same gas:
In such a way, the new volume turns out:
