Volume= Mass/ Density= 20/184
= 0.108 cubic cm
3 elements are present in HCOOH - hydrogen, oxygen, and carbon.
D. The empirical formula and the molar mass
Answer:
Compounds with Carbonate ions are less soluble than the compounds with Chlorate ions.
Explanation:
The reason is that the compounds with carbonate ions have less attraction between positive and negative charges. (Solvation)
Explanation:
Chemical reaction equation for the give decomposition of
is as follows:.

And, initially only
is present.
The given data is as follows.
= 2.3 atm at equilibrium
= 0.69 atm
Therefore,

= 0.23 aatm
So,
= 2.3 - 2(0.23)
= 1.84 atm
Now, expression for
will be as follows.


= 
= 0.0224
or, 
Thus, we can conclude that the pressure equilibrium constant for the decomposition of ammonia at the final temperature of the mixture is
.
