If we count two atoms every seconds, then the time taken to count one mole of atoms that is 6.02×10²³ atoms is 3.0×10²³ seconds. If we continually count the atoms it will take the time which is longer that the age of earth.
What is one mole of atoms?
Any substance that contains 6.02×10²³ atoms is called its one mole. this number that is, one mole of an atom is called the Avogadro number.
The time for counting two atoms is one second then the time to count 6.02×10²³ atoms is 6.02×10²³ /2 = 3.0×10²³ seconds.
One year have about 31556926 seconds. 3.0×10²³ seconds comprises 3.0×10²³ /31556926 = 9.53×10¹⁵ years. Age of earth is 4.5 × 10⁹ years.
Therefore, it will take longer time to count one mole of atoms than the age of earth.

Answer:
In thermodynamics, the triple point of a substance is the temperature and pressure at which the three phases of that substance coexist in thermodynamic equilibrium. It is that temperatureand pressure at which the sublimation curve, fusion curve and vaporisation curve meet.
Answer:
At the triple point, all three phases (solid, liquid, and gas) are in equilibrium. Since the triple point is a point, there is only one temperature and one pressure where the three phases will exist. This fact often helps in identifying compounds or in problem solving.
Answer:
Particulate
Explanation:
Ash, dust, pollen, and tiny bits of salt from water are all examples of particulate
Answer: -2
EXPLANATION
Valence refers to the number of electrons that an atom must borrow or lend to complete its outermost shell. An atom of oxygen wants to add two more electrons to complete its outer shell of eight electrons. Since doing so would result in the oxygen atom becoming negatively charged by accepting two more electrons, oxygen is said to have a valence -2
-2
this is the answer
C6H14 = CCl4 (C6H14 won't mix with water at all)
Na2S = water (Na2S is a salt. Salts dissolve best in water)
Br2 = CCl4, but it will also dissolve in water.
