Answer:
i have taken environmental science so i can help
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
Arachnids lack antennae. The main differences between insects and arachnids are in their body structure and legs.

What are insects?</h3>
Both insects and arachnids are multi-legged creatures that tend to elicit fear, and while they have a lot in common, including that fear response, there are some distinct differences between the two.
The main differences between insects and arachnids are in their body structure and legs.
Arachnids have eight legs, whereas insects only have six. Arachnids have simple eyes, whereas insects have compound eyes. Arachnids lack antennae while insects do.
Therefore, Arachnids lack antennae. The main differences between insects and arachnids are in their body structure and legs.
