Explanation:
21.0 g of potassium reacts with 62.5 g of barium nitride, what mass of potassium nitride will be produced
Answer:
Evaporation
Explanation:
Water in the ocean, rivers, lakes, etc. is part of the hydrosphere, and when that water evaporates it enters the atmosphere
From erosion i think good luck :D
Answer:
What is a Metal ? Metals. Metals are opaque, lustrous elements that are good conductors of heat and electricity. Most metals are malleable and ductile and are, in general, denser than the other elemental substances.
Explanation:
Metalloid, in chemistry, an imprecise term used to describe a chemical element that forms a simple substance having properties intermediate between those of a typical metal and a typical nonmetal. ...
Definition: The non-metals are elements on the right of the periodic table
The total pressure is 6.7 atm. The mole fractions of O₂ and Ar are 0.42 and 0.037.
<em>p</em>(Tot) = <em>p</em>(N₂) + <em>p</em>(O₂) + <em>p</em>(Ar) + <em>p</em>(He) = 3.5 atm + 2.8 atm + 0.25 atm + 0.15 atm = 6.7 atm
χ(O₂) = p(O₂)/p(Tot) = 2.8 atm/6.7 atm = 0.42
χ(Ar) = p(Ar)/p(Tot) = 0.25 atm/6.7 atm = 0.037
