Molar mass Na2CO3 = 106 g/mole
Using dimensional analysis:
0.787 moles Na2CO3 x 106 g/mole Na2CO3 = g Na2CO3
Answer = 83.4 g Na2CO3
It is melting point process
The answer I got is 151. 5 K. I hope that helps.
C
The forward and reverse processes would still be ongoing (the system is not still as in the case of static equilibrium), however, the net effect between the two processes is zero. This is what is referred to as dynamic equilibrium.
A closed system, is one that does not exchange matter or energy between it and the environment.
Explanation:
Take an example of a simplest reversible reaction like the following;
A ⇔ B
To get the dynamic equilibrium constant for the reaction we use the following equation;
Keq = [B]eq / [A]eq
Where eq denotes equilibrium.
An example of a reversible reaction where this applies is;
NH₄Cl (s) ⇔ NH₃ (g) + HCl (g)
