Answer:
![[H_3O^+]=4.7x10^{-3}M](https://tex.z-dn.net/?f=%5BH_3O%5E%2B%5D%3D4.7x10%5E%7B-3%7DM)
Explanation:
Hello there!
In this case, since the ionization of benzoic acid is:
![HC_7H_3O_2+H_2O\rightleftharpoons C_7H_3O_2^-+H_3O^+](https://tex.z-dn.net/?f=HC_7H_3O_2%2BH_2O%5Crightleftharpoons%20C_7H_3O_2%5E-%2BH_3O%5E%2B)
Whereas the corresponding equilibrium expression is:
![Ka=\frac{[C_7H_3O_2^-][H_3O^+]}{[HC_7H_3O_2]}](https://tex.z-dn.net/?f=Ka%3D%5Cfrac%7B%5BC_7H_3O_2%5E-%5D%5BH_3O%5E%2B%5D%7D%7B%5BHC_7H_3O_2%5D%7D)
Now, we insert the acidic equilibrium constant and the reaction extent x, to write:
![6.3x10^{-5}=\frac{x^2}{0.35M}](https://tex.z-dn.net/?f=6.3x10%5E%7B-5%7D%3D%5Cfrac%7Bx%5E2%7D%7B0.35M%7D)
Thus, by solving for x, we obtain:
![x=\sqrt{6.3x10^{-5}*0.35}\\\\x=4.7x10^{-3}M](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B6.3x10%5E%7B-5%7D%2A0.35%7D%5C%5C%5C%5Cx%3D4.7x10%5E%7B-3%7DM)
Which is also:
![x=4.7x10^{-3}M](https://tex.z-dn.net/?f=x%3D4.7x10%5E%7B-3%7DM)
Best regards!
Hey there Fam
the only thing dat brought me here is Soccer ball XD
anyways hahahaha the answer is
C)0.4
thank you
YEEEEET
An ionic bond is a bond between a metal and non-metal
Considering that magnesium is a metal and chlorine is a non-metal an ionic bond will form.
Answer:
n=.849103 moles
Explanation:
We want n, so we change the equation to be n= PV/RT
Then plug in the numbers and solve
n=(3*7.2)/(.08206/310)
n=.849103 moles
Hope this helps
