The answer to your question would be:: the wind because it carries the sand until it runs into an obstacle
"Transition metal elements" are the type of element which have atomic radii which remain relatively constant across a period.
Periods refer to the horizontal lines of the periodic table. Each period represents the sequential occupation of an atom's valence shell orbitals, also with longer periods representing the employment of an atom's d subshell orbitals.
As the atomic number rises, more electrons, as well as protons, are present, increasing attraction over time, which drives the atomic radius to shrink over time.
Therefore, "Transition metal elements" are the type of element which have atomic radii which remain relatively constant across a period.

Answer:
Plants use their leaves to make food. Oxygen is created as a by-product. During photosynthesis, plant leaves take in carbon dioxide from the atmosphere. Using the energy from sunlight, this is combined with water drawn up from the roots to make glucose.

Answer: The mole fraction of neon in the final mixture is 0.6
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.
Given : =total pressure of gases = 5.0 atm
= partial pressure of argon = 2.0 atm
= partial pressure of Neon = ? atm
According to Raoults law, the partial pressure of a gas is equal to its mole fraction mulitiplied by the total pressure.
= mole fraction of Neon
Thus mole fraction of neon in the final mixture is 0.6
