Answer:
pH = 11.37
Explanation:
Sodium cyanide will dissociate into sodium ion and cyanide ion. This cyanide ion will get hydrolyzed.The ICE table for hydrolysis of cyanide ion is:
Initial 0.265 0 0
Change -x +x +x
Equilibrium 0.265-x x x
This K is Kb of HCN
Kb = Kw / Ka
Putting values
x can be ignored in denominator as Kb is very low
x= 2.33X10⁻³ M = [OH⁻]
pOH = -log[OH⁻]
pOH = -log(2.33X10⁻³ )
pOH = 2.63
pH = 14- pOH = 14-2.63 = 11.37
It does not dissolve readily.

Answer:
The steps are arranged in the following order, describing how carbon dioxide and photons impact the earth's warming.
Explanation:
The sequence is in the following order;
- The sun radiated sunlight (visible) photons
- Photons from the sun strike the earth and become infrared photons
- Earth radiates infrared photons into the atmosphere
- CO2 in the atmosphere absorb infrared photons
- CO2 in the atmosphere emit infrared photons back towards earth
Carbon dioxide (CO2) molecules can absorb energy from infrared (IR) radiation. Due to vibrations caused by this absorption, the CO2 molecules later release extra energy by emitting another infrared photon.
This ability of CO2 molecules to absorb and re-emit infrared energy is what makes it an effective heat-trapping greenhouse gas.
