Answer #1

1. Keq = [P]/[SM],where [P] is the products concentration and [SM] is starting material concentrations. Now, if the numerator is much more than denominator then the value of Keq will be large, in other words, the equillibrium will be shifted towards the right, product formation will be more.

2. Complex ions are made of a metal ion which acts as central ion and binds with lignads which could be inorganic anions and organic compounds through dative bonds. These are mainly characteristics of transition element. For an example, hexaaquanickel(II) chloride, [Ni(H2O)5]Cl2.

3. This is called Le Chatelier's principle

Calculating Equilibrium Constants. The equilibrium constant, K, of a reaction at a particular temperature is determined by the concentrations or pressures of the reactants and products at equilibrium. For a gaseous reaction with the general form aA+bB⇌cC+dD the Kc and Kp expressions are given by Kc=[C]c[D]d[A]a[B]b Kp=(PC)c(PD)d(PA)a(PB)b The subscript c or p indicates whether K is expressed in terms of concentrations or pressures. Equilibrium-constant expressions do not include a term for any pure solids or liquids that may be involved...

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...
