PV=nRT⇒P=(nRV)T⇒P=kT where,k=(nRV) or T=k′P where,k=1k′
Can we see you derive one of these equations in class? Sometimes it helps to see it in person rather than just in print.
-
Practice
Would we be able to practice a few problems in class?
-
ideal gas
Is an ideal gas just a hypothetical gas?
-
R=0.082057(L⋅atmmol⋅K)=8.314472(Jmol⋅K)=62.36367(L⋅torrmol⋅K)
Will these values be given on the test?

The geometric structure and the physical and chemical properties of atoms, ions, and molecules usually do not depend on their physical state; the individual water molecules in ice, liquid water, and steam, for example, are all identical. In contrast, the macroscopic properties of a substance depend strongly on its physical state, which is determined by intermolecular forces and conditions such as temperature and pressure.
How does this relate to the arrangement of atoms like carbon, that have many arrangements for the same solid state of matter (like graphite and diamond)?
-
. Water vapor (the term vapor refers to the gaseous form of a substance that is a liquid or a solid under normal conditions so nitrogen (N2) and oxygen (O2) are referred to as gases
I am a little confused as to how water vapor is considered a liquid or gas at normal conditions

Figure 6.1.2:
would we need to memorize the chart and the properties of the gases?
-

Should we memorize any of these values?

What volume of gas would be produced at 760.0 torr and 298 K if 1.00 g of magnesium metal is dropped into 50.0 ml of 1.00 M Hydrochloric Acid?
is it possible to get more questions like this for practice?
