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.
1.4715 atm is the pressure of the sample 1.33 moles of fluorine gas that is contained in a 23.3 L container at 314 K.
What is an ideal equation?
The ideal gas equation, pV = nRT, is an equation used to calculate either the pressure, volume, temperature or number of moles of a gas. The terms are: p = pressure, in pascals (Pa).
Given data:
Volume (V) = 23.3 L
Number of mole (n) = 1.33 moles
Temperature (T) = 314 K
Gas constant (R) = 0.821 atm.L/Kmol
Pressure (P) =?
The pressure inside the container can be obtained by using the ideal gas equation as illustrated below:
PV = nRT
P × 23.3 L = 1.33 moles × 0.0821 ×314 K
P = 1.4715 atm
Therefore, the pressure of the sample is 1.4715 atm.

Answer:
salt (NaCl)
Explanation:
Pure substance is defined as the substance that consist of a single type of material and does not contain contaminants. A pure substance has uniform composition throughout the process.
sodium chloride (NaCl) also known as table salt is a pure substance because it has a uniform and definite composition that is 1:1 ratio of sodium and chloride ions.
Hence, the correct answer is "salt (NaCl)".
Answer:
it will not be soluble in water Becoz it can only be
separated by passing it through silver nitrate solution
