A equals one-half h b plus c in parentheses solve for b?
:a = .5(hb+c) :2a = hb+c :2a−c = hb :(2a−c)/h = b
What does B and B and HB mean?
It is a pencil gradation system. HB means hard black B means black and 2H means harder.H (2H, 4H, etc) are the harder leads, and therefore draw a lighter line; and B (2B, 4B, etc) are the softer leads, and therefore draw a darker line. HB is the very middle. The larger the number, the farther away from HB it is. So for instance, 6B will be darker than 2B, and 4H would be lighter than 2H.Read more: What_do_HB_B_2H_signs_in_pencils_mean

If an equal half of h times b plus c then what would the formula for c in terms of A b and h?
This gives us the equation: A = hb/2 + c To solve for c, we simply subtract hb/2 from each side! A - hb/2 = c c = A - hb/2
What does HB B and 2H mean?
It is a pencil gradation system. HB means hard black B means black and 2H means harder.H (2H, 4H, etc) are the harder leads, and therefore draw a lighter line; and B (2B, 4B, etc) are the softer leads, and therefore draw a darker line. HB is the very middle. The larger the number, the farther away from HB it is.

Prove that Kw equals product of Ka and Kb for an acid-base pair in water?
dissociation of acid in water: A + H2O <-> A- + H3O+ with dissociation constant Ka = [A-][H3O+]/[A][H2O] = [A-][H3O+]/[A]. dissociation of base in water: B + H2O <-> HB+ + OH- with dissociation constant Kb = [HB+][OH-]/[B][H2O] = [HB+][OH-]/[B] dissociation of water in itself: 2H2O <-> H3O+ + OH- with dissociation constant Kw = [H3O+][OH-]/[H2O]^2 = [H3O+][OH-] where [H2O] has been ommitted because it is a pure liquid. substituting relations for Ka and Kb into Kw gives: Kw = [H3O+][OH-] = (Ka[A]/[A-])(Kb[B]/[HB+]) = KaKb where [A] = [HB+] and [B] = [A-].
