Answer:
The net ionic equation is as follows:
HCN(aq) + OH-(aq) ----> H20(l) + CN-(aq)
Explanation:
The reaction between Hydrocyanic acid, HCN, and sodium hydroxide is a neutralization reaction between a weak acid and a strong base.
Hydrocyanic acid being a weak acid ionizes only slightly, while sodium hydroxide being a strong base ionizes completely. The equation for the reaction is given below:
A. HCN(aq) + NaOH-(aq) ----> NaCN(aq) + H2O(l)
Since Hydrocyanic acid is written in the aqueous form as it ionizes only slightly and the ionic equation is given below:
HCN(aq) + Na+(aq)+OH-(aq) ----> Na+(aq)+CN-(aq) + H2O(l)
Na+ being a spectator ion is removed from the net ionic equation given below:
HCN(aq) + OH-(aq) ----> H20(l) + CN-(aq)
Answer:
b)
Explanation:
It shows the natrual proggresion of a story and helps blend the narrtive together.
It is graphical representation of the solubity of a particular solute in a given solvent with respect to varying temperatures,generally,temperature is directly porportional to solubity,as temperature increases solubity increases.
The rate expression of the change in b with time is
rb = k [b]
This is for the formation of b assuming that the reaction is first order with respect to b
For the reaction equation, the expression is
-rb = -k [b]
Again, assuming that the reaction is first order with respect to b
Try looking this stuff on Google ITS GREAT!!
