Outer core. The outer core of the Earth is a fluid layer about 2,300 km (1,400 mi)[1] thick and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. Its outer boundary lies 2,890 km (1,800 mi) beneath Earth's surface. The transition between the inner core and outer core is located approximately 5,150 km (3,200 mi) beneath the Earth's surface. Unlike the inner core, the outer core is liquid. The inner core is also referred to as the solid core.
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.
Balanced Chemical Equation  Tells us which substances are the products and which substances are the reactants, and the relative amounts of each. Balancing Chemical Equations. In class demo Electrolysis of Water. The reaction that is taking place right now is the decomposition of water into hydrogen and oxygen.Water Hydrogen + Oxygen. In this example water is the reactant (it will be completely destroyed if the reaction goes to completion), while hydrogen and oxygen are the products (they are created by this chemical reaction).alanced Chemical Equation  Tells us which substances are the products and which substances are the reactants, and the relative amounts of each.
