Balance the chemical equation for the combustion of pentane: C5H12 (g) + O2(g) → CO2 (g) + H2O (g) EXPLANATION: There are three steps involved in the systematic balancing method: Step 1: Make a table that lists the elements that are present and count all atoms on each side of the unbalanced equation. • If H2 or O2 is present, list these elements last. • A polyatomic ion may be counted as one “element” if it appears on both sides of the equation. Step 2: Balance an element in the table by adding coefficient(s) to the equation (start with the first element on the list). Step 3: Recount each atom and update the table, then repeat Steps 2 and 3 for all elements as needed until the equation is balanced. Can you help me to show step by step?
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
