Over the years, the thermite reaction has been used for welding railroad rails, in incendiary bombs, and to ignite solid fuel rocket motors. The reaction is:math> Fe 2 O 3 ( s ) + 2 Al ( s ) → 2 Fe ( l ) + Al 2 O 3 ( s )l type='a'>What mass of iron(III) oxide must be used to produce 25.69 g of iron?What mass of aluminum must be used to produce 25.69 g of iron?What is the maximum mass of aluminum oxide that could be produced along with 25.69 g of iron?
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.
