Answer:
The free energy change for the reaction at 37.0°C is -8.741 kJ.
Explanation:
The free energy of the reaction is given by :
where,
= standard Gibbs free energy
R = Gas constant =
T = temperature in Kelvins
K = equilibrium constant
We have :
1 kJ = 1000 J
T = 37.0 C = 37 +273.15 K = 310.15 K
Ratio of concentrations of the products to the concentrations of the reactants =K = 21.9
The free energy change for the reaction at 37.0°C is -8.741 kJ.
Answer:
2P4O10 + 2H2O → 2H3PO4
Balanced Equation → P4O10 + 6H2O → 4H3PO4
Tetraphosphorus Decaoxide + Water → Phosphoric Acid
Reaction Type → Synthesis
Answer:
SEPARATION SCHEME FOR CATIONS
GIVEN CATIONS :
Step 1: Add of
to the mixture solution
Result : This would cause a precipitate of to be formed
Reaction :
Step 2 : Next is to remove the precipitate and add to the remaining
solution in the presence of of HCl
Result : This would cause a precipitate of to be formed
Reaction :
Step 3: Next remove the precipitate then add of aqueous
, process the solution in a centrifuge,when the
process is done then sort out the precipitate from the solution
Now this precipitate is and the remaining solution
contains
Next take out the precipitate to a different beaker and add HCl
to it this will dissolve it, then add a drop of this will
form a precipitate which will have the color of
blood indicating the presence of
Reaction :
Now the remaining mixture contains
