Question #c799c

↳Redirected from "Suppose that I don't have a formula for #g(x)# but I know that #g(1) = 3# and #g'(x) = sqrt(x^2+15)# for all x. How do I use a linear approximation to estimate #g(0.9)# and #g(1.1)#?"

Copper(II) chloride.

Explanation:

Copper's symbol is #"Cu"# and chlorine's symbol is #"Cl"#. Copper is a transition metal, so its charge can vary. Because of this variance, the copper cation needs to have the #(II)# after it.

The #II# is roman numerals for positive two, or #+2#. And lastly, because the chloride anion is #-1#, and the copper cation #+2#, there must be two chlorines, making #"CuCl"_2#.
