The degree to which various compounds will dissociate in solution varies greatly.
1 answer:
Answer: True
Explanation:
Weak electrolytes are those solutions which do not undergo complete dissociation when dissolved in water. The dissociation of weak electrolytes is given by an equilibrium.
Example:
Strong electrolytes are those solutions which undergo complete dissociation when dissolved in water. The dissociation of strong electrolytes is given by a right arrow.
Example:
Thus the degree to which various compounds will dissociate in solution varies greatly is true.

Answer:
5.25 moles.
Explanation:
The decomposition reaction of NaN₃ is as follows :
We need to find how many grams of N₂ produced in the process.
From the above balanced chemical reaction, we conclude that the ratio of moles of sodium azide and nitrogen gas are 2 : 3.
2 moles of sodium azide decomposes to give 3 moles of nitrogen gas. So,
3.5 moles of sodium azide decomposes to give moles of nitrogen gas.
Hence, the number of moles produced is 5.25 moles.
