A candle is placed on one pan of a balance, and an equal weight is placed on the other pan. What wouldhappen if you lit up the candle and waited for a while?2. Suppose the candle was placed in a large, sealed jar that allowed it to burn for several minutes beforerunning out of oxygen. The candle and jar are balanced by an equal weight. In this situation, what wouldhappen if you lit up the candle and waited?Gizmo Warm-upBurning is an example of a chemical reaction. The law of conservation of matter states that no atoms arecreated or destroyed in a chemical reaction. Therefore, a balanced chemical equation will show the samenumber of each type of atom on each side of the equation.To set up an equation in the Chemical Equations Gizmo, type the chemical formulas into the text boxes of theGizmo. First, type in "H2+02" in the Reactants box and "H2O" in the Products box. This represents thereaction of hydrogen and oxygen gas to form water.ReactantsProductsH2+02H2O1. Check that the Visual display is chosen on each side of the Gizmo, and count the atoms.A.How many hydrogen atoms are on the Reactants side?Products side?В.How many oxygen atoms are on the Reactants side?Products side?2. Based on what you see, is this equation currently balanced?

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.
