What is the pressure of 5.0 mol nitrogen gas in a 2.0 L container at 286 K
1 answer:
The "Ideal Gas Law Equations" is
P= Pressure (in Pascals)
V=Volume (in Liters)
n=amount, or <u>n</u>umber (in moles)
R= 8.3145
or 
T= Temperature (In Kelvin)
Plug into the equation and you're good!
If your teacher cares about sig figs,
2 sig figs (significant figures)
For other units of pressure,
1 atm = 760 mmHG = 760 Torr = 101326 Pa = 1.01325 bar<u />

Answer: c.They have a unique set of properties that can be used as identifiers.
Explanation:
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.
Compounds can be decomposed into simpler constituents using chemical reactions.
Example: Water
Compounds have different properties than the elements it is made up of.
Thus the most accurate description of compounds is that they have a unique set of properties that can be used as identifiers.
