Pentane gas (C5H12) combusts with oxygen gas (O2) to form water (H2O) and carbon dioxide(CO2). Write a balanced chemical equation for this reaction and explain the scientific principle(statement) that requires the balancing of an equation to make it conform to reality.ScoreAnswer:Place the reactants on the left side and the products on the right side of the equation.C5 H12 ( g ) O2 ( g ) H 2O(l ) CO2 ( g )To begin, balancing start with the carbon.C5 H12 ( g ) O2 ( g ) H 2O(l ) 5CO2 ( g )Then balance the hydrogen by increasing the number of waters.C5 H12 ( g ) O2 ( g ) 6H 2O(l ) 5CO2 ( g )Finally, balance the oxygen. There are 6 + 5*2 = 16 oxygens on the right. We need an equal amount on the left.C5 H12 ( g ) 8O2 ( g ) 6H 2O(l ) 5CO2 ( g )The law of cons ...
