E=MC(delta)T
=20.0g x 9.00J/g x (94.4-22.8) C
= 12,924.0 J
No they're closer due to the oxygen in the water
What about it? We need information in order to answer it! :)
Ernest Rutherford discovered the electron cloud.
Answer:
Explanation has been given below
Explanation:
- Rate law =
, where k is rate constant and species inside third bracket represents concentrations. - Clearly, rate depends upon concentration of free

- In acidic medium (pH = 5.6), concentration of free
is negligible as HCN is a weak acid. So, reaction between benzaldehyde and HCN does not occur at all. - In neutral medium (pH = 7), concentration of cyanide ion somewhat increases. Therefore reaction is slow in neutral pH
- In basic medium (pH > 7), concentration of cyanide ions become sufficient to make the reaction spontaneous. In basic condition, concentration of cyanide increases due to increase in ionization of HCN
- Full reaction mechanism has been shown below.
