Consider the family of hyperbolas given by: x^2 -((y^2)/2)=c For each given c 2 R the curve can be thought of (locally) as an implicit function of y, i.e., y(x). Describe (with a family of equations) the family of curves which are orthogonal to the family of hyperbolas above.

The density of chloroform, a widely used organic solvent, is 1.4832 at 20 . How many milliliters would you use if you wanted 119.0 of chloroform.
The four molecular p orbitals of the four carbon atoms can be lined up parallel in order to create four new molecular orbitals. The electrons in the new molecular orbitals benefit because they are not confined to just one atom.
When ammonium nitrate is added to water, the temperature of H2O drops, but when sodium hydroxide is added to H2O, the temperature rises. Explain why the temperature of water can change in different ways when an ionic substance is added.
25.0 mL of a hydrofluoric acid solution of unknown concentration is titrated with 0.200 M NaOH. After 20.0 mL of the base solution has been added, the pH in the titration flask is 3.00. What was the concentration of the original hydrofluoric acid ..
