Web23 mrt. 2024 · The dissociation constant K a is [H3O+] [CH 3 CO 2-] / [CH 3 CO 2) H]. K a = x 2 / (0.9 - x) As noted above, [H3O+] = 10 -pH. Since x = [H3O +] and you know the pH of the solution, you can write x = 10 -2.4. It is now possible to find a numerical value for Ka. Ka = (10 -2.4) 2 / (0.9 - 10 -2.4) = 1.8 x 10 -5. Cite this Article WebFind the value of k for which the constant function x ( t) = k is a solution of the differential equation 5 t 2 x ′ − 2 x + 4 = 0.

WebDetermine whether a number is a solution to an equation. Substitute the number for the variable in the equation. Simplify the expressions on both sides of the equation. Determine whether the resulting equation is true. If it is true, the number is a solution. If it is not true, the number is not a solution. example Web2 mrt. 2024 · In this post, a special case is discussed when k = 2 Examples : Input : n = 5 Output : The person at position 3 survives Explanation : Firstly, the person at position 2 is killed, then at 4, then at 1 is killed. Finally, the person at position 5 is killed. So the person at position 3 survives. flights from grand rapids michigan to florida
