One reactant goes into iridium, how many products come out? What did you see when you were watching the reaction occur? What evidence in the equation matches the observation? Are the products examples of atoms, elements, or compounds? What happened to the iridium catalyst during the change? The product words read “nitrogen and hydrogen gas”. The equations tells us the state of matter, too. What evidence in the equation tells us the state of matter What state of matter is the hydrazine reactant?
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.
