Homework Statement It's not an homework question. I'm trying to figure out this problem, but don't have any idea... The question is, if 3.0 moles of gas has a volume of 66 L, then what is the molar volume of this gas? I did like, 22.4 L * 1 atm / 273 K = 66 L * 1 atm / x, but what do...

=>>> I wrote the answer for this question like this. Because the photons are absorbed by an atom, an election attains a higher energy orbital. The electron won't stay up there. The electron falls to a lower energy level and a new photon is emitted. The photon is emitted in a more or less...

=>>> Thanks a lot... you helped me so much... : ) but... I don't get the first problem about light. Do you remember the question about spectrum?

=>>> I think H2SO4(aq) is dissociate like H+(aq) + HSO4-(aq). How 2 hydrogens should be canceled out? And I canceled out 2NO3 each side.

=>>> I already know that part. I just want to check the final ionic equation. Anyway I edited.

[SIZE="3"]Find the molecular, total ionic, and net ionic equation for the aqueous reaction between strontium nitrate and sulfuric acid. I did like this, please check this out... [SIZE="4"]Sr(NO3)2 + H2SO4 -> 2HNO3 + SrSO4 is molecular equation. Sr+2(aq) + 2NO3-1(aq) + H+1(aq) + HSO4-1(aq)...

Homework Statement Why does chromium(III) absorb light? Explain what is happening on an atomic level. -> I don't really get this problem. Can you help me out...? Please... Homework Equations The Attempt at a Solution

Thanks!

1. Benzylamine, C6H5CH2NH2 is dissolved in water and tested with a conductivity meter. The result is a dim light. Is this compound an electrolyte? If so, what are the ions? 2. I know that it's compound an electrolyte, but I don't know what are the ions in there.
