At what temperature (in Kelvin) would 5.0 moles of hydrogen gas in a 150-liter container exert a pressure of 100kPa?
Use the ideal gas law PV = nRT with R= 8.31 L-kPa/mol-K.
150K
265K
326K
361K

the answer is b & c i believe : )

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
