What is the value of Ksp for CuCI?
FacebookTweetPin Given the two reactions:CuCI(s) + Cl–(aq) ⇋[CuCI2]–(aq) K= 5.2×10-2 Cu+ (aq) + 2Cl–(aq)⇋ [CuCI2]–(aq) Kf= 3.0×105What is the value of Ksp for CuCI? Solution: Ksp is the solubility product equilibrium constant. To write the Ksp expression, first you need to write an equation where ionic solid is on the reactant side and aqueous ions it dissociates into are on the product side. CuCl(s)⇋Cu+ (aq) + Cl–(aq).You need to add to equations in such…
Draw structures for all constitutional isomers with the following molecular formula: C2H4Cl2
FacebookTweetPin Constitutional isomers, also called structural isomers, are molecules that have the same molecular formula but different structure. In our case, the molecular formula is C2H4Cl2. All of the constitutional isomers must have two carbons, four hydrogens and two chlorines. We can begin by drawing two carbons. There are two ways to add two chlorines. We…
Learn How To Name Alkanes With Mayya
FacebookTweetPin Alkanes are hydrocarbons that have only single bonds. Before learning how to name alkanes, you need to understand different ways to draw and interpret them. There are three different ways to draw organic molecules: Lewis structure, condensed structure and bond-line structure. Bond-line structures are used most often in organic chemistry. In a bond-line structure,…
