Question

What is the value of the Ideal gas constant?

Answer 1

It all depends on your units .
\[\Large R=k \times N_{A}=8.314 \sf \frac{ J }{ mol \times K }\]
\(\large R\) is the gas constant
\(\large k\) is the Boltzmann constant \(\large 1.38 \times 10^{-23} \sf \frac{J}{K}\)
\(\large N_{A}\) is the Avogadro constant \(\large 6.02 \times 10^{23} \sf \frac{1}{mol}\)

Answer 2

I see.. now, thank you :)

Answer 3

No problem.

Answer 4

one more questin though

Answer 5

Sure, shoot.

Answer 6

if we say hydrogen gas, its formula is H2 right?

Answer 7

That is correct.

Answer 8

so Oxygen gas is , O2 ?

Answer 9

Also correct. Both hydrogen and oxygen would be highly reactive when just on the form H and O.

Answer 10

so generally speaking, all elements names with the term "gas" is paired?

Answer 11

Sorry that was bad formulated. When you say "paired" what do you then mean? I mean we could have carbondioxide which is also a gas.
Beside you should remember that most of the element can take all of the states of matter. An example would be helium (He). At room temperature it is a gas but we do have to power to turn it into liquid.

Answer 12

say...

Answer 13

correct

Answer 14

@Frostbite thanks again :) you have cleared my anxiety for the upcoming terrorizing exam ;)

Answer 15

No problem at all, and good luck! :)

Answer 16

@Frostbite cheers! :)
