How do you form a straight line equation given only the points of k 3h and 3k h?
With difficulty if you don't know the methods and one of the methods is as follows:- Let the points (k, 3h) and (3k, h) be (x1, y1) and (x2, y2) respectively: (y-y1) over (y2-y1) = (x-x1) over (x2-x1) (y-3h) over (h-3h) = (x-k) over (3k-k) (y-3h) over (-2h)) = (x-k) over (2k) Multiply both sides by -2hk to eliminate the fractions: k(y-3h) = -h(x-k) ky-3hk = -hx+hk ky = -hx+hk+3hk ky = -hx+4hk The above straight line equation can be expressed as: hx+ky-4hk = 0

What is the straight line equation in its general form connected by the end points of k 3h and 3k h on the Cartesian plane showing work?
Points: (k, 3h) and (3k, h) Slope: h-3h/3k-k = -2h/2k => -h/k Equation: y-3h = -h/k(x-k) => ky-3hk = -h(x-k) => ky = -hx+hk+3hk Equation in its general form: hx+ky-4hk = 0

When 15.12 ml of 0.1194 M NaOH is added to 25.00 ml of 0.1246 M HX an unknown weak acid the resulting pH is 5.9. What is the Ka of the unknown acid?
I think I'm on the right track but I'm not sure of how it is finished; Since the equation representing the dissociation of HX is as follows; HX(aq) + H2O (l) <--> H3O+(aq) + X-(aq) It can then be shown that the equilibrium constant is found as such; Ka = [H3O+][X-]/[HX] (Note: H2O is not in the equilibrium equation because it is a liquid and further, the solvent) I first found [HX] as follows; [HX] = ((0.1246 M HX) x (25.00 mL) x (1L/1000 mL))/(40.12 mL x 1000 mL/1L) [HX] = 0.07764 M HX I then found the [H3O+] by converting the pH into [H3O+], given that pH = -log[H3O+] which results in; 5.9 = -log[H3O+] [H3O+] = 1.3x10-6 M Now as to how we solve for [X-] I'm not sure if [X-] = [H3O+] or what but if anyone can tell me if I'm completely off or somewhere near where I want to be perhaps they can finish it for you or give you the right answer

What does the medical abbreviation Hx mean?
Hx is an abbreviation for history.Hx means medical history on documents such as discharge papers and shot records.
What is the acid dissociation constant for an acid at equilibrium HX H X?
The acid dissociation constant, Ka, is the ratio of the concentrations of the products (H+ and X-) to the concentration of the reactant (HX) at equilibrium. It is usually expressed as [H+][X-]/[HX]. The larger the Ka value, the stronger the acid.
