The compound Na2S or Sodium sulfide is soluble in
water. This compound is a water-soluble salt that give strong alkaline
solutions. When exposed to air or humidity this compound gives-off hydrogen sulfide
that smells almost the same as rotten eggs.
This chemical is commonly used in the pulp and
paper industry. Sodium sulfide compounds are usually used in chemical
photography, textile bleaching, making dyes, and even detergents.
<span>The other 3 compounds are non-soluble in water. Their
compositions are mostly metal in nature and require other process to transform
them into different compound forms. </span>
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
![\Delta G=-16,700 J/mol+8.314J/K mol\times 310.15 K \ln[21.9]](https://tex.z-dn.net/?f=%5CDelta%20G%3D-16%2C700%20J%2Fmol%2B8.314J%2FK%20mol%5Ctimes%20310.15%20K%20%5Cln%5B21.9%5D)
The free energy change for the reaction at 37.0°C is -8.741 kJ.
count the elements in eqn MgI2 + Br2 -> MgBr2 + I2
1 Mg, 2I, 2Br on the left n
1 Mg, 2I, 2Br on the right
they are equal so the eqn is balanced
False they still can as the shockwaves can be very strong
