Chemical reaction: C₃H₇COOH → C₃H₇COO⁻ + H⁺.
c(<span>butanoic acid) = 0,100 M.
</span>α = 1,23% = 0,0123.
Ka = α² · c / 1 - α.
Ka = 0,0123² · 0,1 M / 1 - 0,0123.
Ka = 0,0000153 M.
Ka = c(C₃H₇COO⁻) · c(H⁺) / c(C₃H₇COOH).
c(H⁺) = α · c(C₃H₇COOH).
c(H⁺) = 0,0123 · 0,1 M = 0,00123 mol/L.
pH = -log c(H⁺).
pH = 2,91.
The family of poison dart frogs (Dendrobatidae) boasts over 245 species, displaying an astonishing array of colors and potency. The brilliant colors and patterns range from strawberry red, canary yellow, and sunny orange to metallic green and black with yellow polka-dots. When eaten, some merely taste bitter or irritate the predator’s mouth with burning or numbness; a few, however, are truly deadly, even to humans. the Golden poison frog is <span>the deadliest animal on land(poison wise) but the Black-legged poison frog is right up there next to it. both can easily kill a human. Though no deaths have been confirmed, the Kokoe poison frog can theoretically also kill a human, it is just as toxic as the black-legged poison frog. so what do they all have in common? they can all kill humans
i hope this helps, please give me brainliest </span>
Answer:
164atm
Explanation:
Given parameters:
Initial pressure = 150atm
Initial temperature = 27°C = 27 + 273 = 300K
New temperature = 55°C = 328K
Unknown:
New pressure = ?
Solution:
At constant volume, the pressure of a given gas varies directly with the absolute temperature.
Mathematically;
= 
P and T are pressure and temperature values
1 and 2 are the initial and new states
Insert the parameters and solve;
= 
300P₂ = 150 x 328
P₂ = 164atm
