Carbon-based materials such as steel and wood are very stable, well-designed structures. They last for years without needing renovation or replacement.
In order for a material to undergo an reaction, it must have a basic component and an acidic component. The basic component can be anything from oxygen to aqua. The acidic component can be something strong or weak, depends on the material.
A reaction that happens quite frequently is when oxygen gets into water and reacts with aqua to produce oxygen and aqua, called oxygenation.
Calculate the moles of each reactant
When you analyze a reaction, called an equation, you determine the number of elements involved in the reaction, called the elements in the equation.
The elements must be present at a certain concentration for the reaction to take place. For example, when you bring together two chemicals, one that doesn’t react and one that does, you need enough of the chemical to cause it to combine.
The amount of bromide that reacts with potassium iodide is 1/2 of 1 gram (0.05 mole). Potassium iodide has a theoretical yield of 0.005% so this is very small amounts of bromide that combine with it.
An important part of finding an accurate equation for a reaction is knowing how many elements are involved.
Write the reaction equation
In the case of the reaction equation, the two substances are called chemicals. In this case, the two chemicals are Fe2+, and Pb2+, which is called an ion.
Fe2+ and Pb2+ are chemically interchangeable and present in almost every solution. When precipitating a solution with binary compounds, you must use an appropriate chemical combination.
When adding a solid to a liquid, you must use an appropriate density of solids. When adding a liquid to a solid, you must use an appropriate solvent. All of these factors must be considered when writing the reaction equation for the alloying reaction.
To draw an alloying reaction equation, first determine whether or not there is a balance between two or more elements in the system. Then determine what element is dominant and how it affects other elements in the system.
Balance the oxygen atoms
When you add two chemicals, it can create a reaction that depends on another molecule. For instance, when you mix chlorine and sodium chloride, the Na+ + Cl- reacts to produce Se+ + Cl- .
The reaction depends on oxygen atoms for both the Na+ and the Cl-. So, when creating a reactionequation for a chemical reaction, find an oxygen atom for each step of the reaction and add them together to form the next step of the Reaction Equation.
In this case, Feso4 + Pb(no3)2 reacts to form Pb(no3)2 + Fe2+. The second phase is called an octahedral phase and consists of lead zirconium dioxide (Pb(zrO))2. This is an important component in treating land mines (land mines are devices that tell people where to go and what direction to take while fighting).
Balance the nitrogen atoms
In order for a reaction to occur, there must be a source of nitrogen (e.g. air) or removal of nitrogen (e. g. heat). In order for a reaction to proceed, it must be balanced between the two sides of the equation.
The total amount of reactivity of a chemical is called its equilibrium constant. When preparing reactions, you will most often find that the reactivity is low at the start and increases as the reaction progresses. This is because at first there is not enough energy in the reactivity to complete the reaction!
There are four ways to give feedback on whether or not a reaction is balanced: number of products, width of spectrum, presence or absence of an effect and balance between two reagents which form a compound with one another.
Balance the lead atoms

If two bromine atoms are present, then one of them must be relatively stronger than the other. This may be the case for this reaction because bromine is fairly reactive and may alter other compounds leaving them less stable.
However, if there are no other atoms present than lead, then there must be a sufficient amount of Br+ to cover up the weaker material. There must also be enough no3to cover up any excess of Br+ which would cause an imbalance in the reaction.

Add a final compound and its formula
In the example of Mg2+ + 2 NaOH → MgNaOH + 2 Na, we add another compound, K2SO4. This is due to the reaction being an acid-base exchange reaction.
In this case, K2SO4 is dissolving in the reactant solution. As a result, the original solution changes from white to orange as it contains both Mg2+ and K2SO4.
This phenomenon is called a solute and its anion. The solute acts as a base while the anion raises acidspinal (Aa) and strength (S) of the reaction.
K2SO4 is a strong base that causes some solid solutions to dissociate into K+ and SO42– which are acidspinal compounds. As a result, these solutions change color.
Check your work
If your equation does not match the reaction, try to make a similar one. For instance, if your reaction states that R and S react to form R-S complex, then try adding H or an amine to see if that changes the reaction.
Some reactions require more information to determine how much of each chemical is involved. These include some rare reactions and those that require large amounts of one reagent or material. These are highlighted in the following article.

If you find that your table requires more than three blank lines to hold all of the data, then increase the temperature at which the reaction takes place.
