Answer : The pH of the solution is, 9.63
Explanation : Given,
The dissociation constant for HCN =
First we have to calculate the moles of HCN and NaCN.
and,
The balanced chemical reaction is:
Initial moles 0.1116 0.0461 0.08978
At eqm. (0.1116-0.0461) 0 (0.08978+0.0461)
0.0655 0.1359
Now we have to calculate the pH of the solution.
Using Henderson Hesselbach equation :
Now put all the given values in this expression, we get:
Therefore, the pH of the solution is, 9.63
Non metal atoms got this from google btw
This movement is known as convection or convection currents. This occurs due to the fact that warmer fluid is of lower density than colder fluid. This causes warmer fluid to rise and colder fluid to sink. This creates circulatory currents within the body of the fluid.
Okay.. so I guess this is how it goes:
1. Rainforest
2. Temperate deciduous
3. Marine
4. Taiga
5. Tundra
Pls don't completely rely on it, this is my best guess and it's probably right except with Marine life and temperature deciduous. 70% I feel like it would temperate then marine. But check with urself again. Hope this helped..
