Answer:
4.23.
Explanation:
<em>∵ pH = - log[H⁺].</em>
<em>For weak acids:</em>
∵ [H⁺] = √(ka)(c).
∴ [H⁺] = √(3.5 × 10⁻⁸)(0.10 M) = 5.92 x 10⁻⁵.
∴ pH = - log[H⁺] = - log(5.92 x 10⁻⁵) = 4.2279 ≅ 4.23.
both of the answers are bone
Explanation:
Mark me as brainliest
Buoyancy is a condition in which a physical body's average density is equal to the density of the fluid in which it is immersed.
The buoyancy offsets the force of gravity that would otherwise cause the object to sink (if the body's density is greater than the density of the fluid in which it is immersed) or rise (if it's less). An object that has neutral buoyancy will neither sink nor rise.
Hope this helps! xx

Answer:
The pressure is ![[O_2] = 4.8 *10^{-5} \ atm](https://tex.z-dn.net/?f=%5BO_2%5D%20%3D%20%204.8%20%2A10%5E%7B-5%7D%20%5C%20atm)
Explanation:
From the question we are told that
The pressure of
is ![[SO_3 ] = 0.63 \ atm](https://tex.z-dn.net/?f=%5BSO_3%20%5D%20%3D%20%200.63%20%5C%20atm)
The pressure of
is ![[SO_ 2] = 0.30 \ atm](https://tex.z-dn.net/?f=%5BSO_%202%5D%20%20%3D%20%200.30%20%5C%20atm)
The equilibrium constant is
The reaction is
⇔ 
Generally the equilibrium constant is mathematically represented as

=> ![[O_2] = \frac{k_p * [SO_3] ^2 }{[SO_2]^2}](https://tex.z-dn.net/?f=%5BO_2%5D%20%3D%20%20%5Cfrac%7Bk_p%20%2A%20%5BSO_3%5D%20%5E2%20%7D%7B%5BSO_2%5D%5E2%7D)
substituting values
![[O_2] = \frac{1.2 *10^{-5} * 0.60 ^2 }{0.30^2}](https://tex.z-dn.net/?f=%5BO_2%5D%20%3D%20%20%5Cfrac%7B1.2%20%2A10%5E%7B-5%7D%20%2A%200.60%20%5E2%20%7D%7B0.30%5E2%7D)
![[O_2] = 4.8 *10^{-5} \ atm](https://tex.z-dn.net/?f=%5BO_2%5D%20%3D%20%204.8%20%2A10%5E%7B-5%7D%20%5C%20atm)
