1. What volume is required to contain 100.0 mol O2 at STP?

Colt1911 [192]

Answer:

The volume is 2238,6 L

Explanation:

We use the formula PV=nRT. The conditions STP are: 1 atm of pressure and 273K of temperature:

PV=nRT ---> V=(nRT)/P

V= 100 mol x 0,082 l atm/K mol x 273K/ 1 atm

Explanation:

On dissolution of chromium(II) sulfate is water 2 ions of chromium(III) ion and and 3 sulfate ions are formed.

The balanced chemical equations of the dissolution of chromium (II) sulfate:

$Cr_2(SO_4)_3(aq)\rightarrow 2Cr^{3+}(aq)+3SO_4^{2-}(aq)$

On dissolution of gold(III)nitrate is water 1 ions of gold(III) ions and and 3 ions of nitrate ions are formed.

The balanced chemical equations of the dissolution of gold(III) nitrate:

$Au(NO_3)_3(aq)\rightarrow Au^{3+}(aq)+3NO_3^{-}(aq)$
