What is the value of the equilibrium constant (K) for the following neutralization reaction: H3O+ + OH- 2H2O Remember: if you want to express an answer in scientific notation, use the letter "E". For example "4.32 x 104" should be entered as "4.32E4". Answer: Check

Partial Differential Equations Please provide the solution with steps. Thanks!   Consider a thin tube of length \( L \), oriented along the \( \mathrm{x} \)-axis. The tube is sealed at both ends. A finite amount of dye molecules is injected just inside this tube near one of its ends. You should assume that the concentration of dye molecules \( c(x, t) \) obeys the 1D diffusion equation given by \[ \frac{\partial c}{\partial t}=D \frac{\partial^{2} c}{\partial x^{2}} \] (a) Consider Fick's law and show that the following are appropriate boundary conditions \[ \left.\frac{\partial c}{\partial x}\right|_{x=0}=\left.0 \quad \frac{\partial c}{\partial x}\right|_{x=L}=0 . \] (b) If the local injection of dye at position \( x_{0} \) (close to origin end of tube at \( \mathrm{x}=0 \) ) and \( t=0 \) can be described by \( \alpha \delta\left(x-x_{0}\right) \), determine the value of \( \alpha \) in terms of the total number of molecules \( N \). (c) Use the separation of variables method, to show that the a solution to the diffusion equation for a tube of length \( L \) can be written as \[ c(x, t)=A_{0} x+B_{0}+\sum_{n=1}^{\infty}\left(A_{n} \cos \frac{n \pi x}{L}+B_{n} \sin \frac{n \pi x}{L}\right) e^{-D\left(\frac{n \pi}{L}\right)^{2} t} . \] (d) Now consider the boundary conditions noted in a) together with the initial dye injection constraints, and use these to determine the coefficients and thus the solution for \( c(x, t) \).

1-)A 26.1 mL solution of HBr (a strong acid) of unknown concentration was titrated using 0.6088 mol L-1 NaOH using phenolphthalein as a pH indicator. At the moment when the solution turned a consistent light pink colour, the burette volume read 28.65 mL. The initial burette reading before the experiment was 7.70 mL. What was the concentration of HBr in the original HBr solution in mol L-1 2-)What is the value of the equilibrium constant (K) for the following neutralization reaction: 𝐻3𝑂++𝑂𝐻−⟶2𝐻2𝑂H3O++OH−⟶2H2O Remember: if you want to express an answer in scientific notation, use the letter "E". For example "4.32 x 104" should be entered as "4.32E4". Hint: To answer this question, you may need to use the value of Kw stated in the lab manual.
