The Role of Stoichiometry in Balancing Chemical Equations
The role of Stoichiometry in balancing chemical equations is critical as it assists to explain all the steps in detail and reactions
The role of Stoichiometry in balancing chemical equations is critical as it assists to explain all the steps in detail. “The simple definition of Stoichiometry is to balance the proportional quantities of the reactant and the products in a chemical reaction”. The free online stoichiometry calculator makes it possible to balance chemical equations and their proportional ratio at a specific time of the reaction.
It is essential for the learners to first completely understand the concept of stoichiometry. Stoichiometry enables us to determine the result of the reaction before it is carried out, by entering the data in the stoichiometry formula. This result is used to mix the specific concentration of the reactants to attain the specific molar concentration of the products.
What is Stoichiometry?
Stoichiometry is a section of chemistry to get the desired quantitative product by using the proportional quantities of the reactant. In Greek, the word “Stoikhein” means the elements and the “Metron” means the elements. So literally the meaning of stoichiometry is the determination of the proportional qualities of the reactant and the product according to the “law of the conservation of mass”.
What are the Stoichiometric Coefficients?
“The stoichiometry coefficients are the number of moles of the reactant and the product in the chemical equation”.
When you are able to find the stoichiometry coefficient, then you can mix the molar concentration at a specific temperature and pressure. The stoichiometric coefficients can also be fractions or ratios but the whole numbers are preferred to represent the near-to-exact proportionality of the reactants and the products.
The gas stoichiometry calculator by calculator-online.net only uses the whole number to estimate the proportional ratio of the reactants and the products. It assists to avoid any kind of ambiguity and complication during the chemical reaction.
Different Types of Stoichiometry Balancing Chemical Equations
There are the following types of stoichiometry that are essential to understand while balancing a chemical equation. So, the stoichiometry calculator automatically converts the molar concentration into the atomic weight. For example, if the molar concentration of water H2O is equal to 2. Moreover, the molar concentration can be converted into the atomic weight as follows:
The molar concentration of water = 2H2O
The atomic weight of water = 2(1)+(16)= 18 grams
For 2 moles of water= 2(18) = 36 grams.
Moles To Moles Stoichiometry:
If in a reaction, you need to determine the Moles To Moles Stoichiometry, then follow the steps:
- Firstly, convert the units of reactants and products into the corresponding number of moles.
- Secondly, once you calculate the moles of the reactants and the product, adjust the chemical equation
- Finally, there should be an equal number of moles of the reactant and the product in the balanced chemical equation
Mass To Mass Stoichiometry:
The other method of balancing a chemical equation is by balancing the masses of the reactant and the product.
- Firstly, in the first step Write down the balanced stoichiometry of chemical equations
- Secondly, Convert the reactant atomic mass into an equal number of moles
- Find the moles of the desired product and its atomic mass
- Now finally balanced the atomic masses of the reactant and the products in the chemical equation.
You can choose the stoichiometry calculator to find the molar stichometry or the Mass To Mass Stoichiometry of the chemical equation. So, you just need to enter the chemical equation in the online calculator with the role of stoichiometry balancing reactions.
Practical Example Balancing Chemical Equations
Suppose you are experiencing the rusting of the iron metal and the iron is reacting with the oxygen of the air to make the Iron Oxide. If we want to write down the stoichiometric equation, you need to follow the steps written below:
Do the stoichiometric calculations as below:
Step # 01:
The balanced chemical stoichiometry equation of the iron oxide formation reaction is written as
4Fe+3O2→2Fe2O3 Balancing Chemical Equations
Step # 02:
You need to find the atomic weight and the molecular masses for each element of the reactant and the product with the role of stoichiometry balancing reactions.
Oxygen =O= 16
For calculations and steps, tap the atomic mass calculator.
Fe2O3 = 2(26)+3(16) = 104
Here with the help of another molecular formula calculator, you can get to know the steps involved in calculating the molecular mass of any compound.
The above information can also be displayed in the following stoichiometry table:
|Atomic Mass||Molecular Mass|
|O = 16|
Step # 03:
Balance the chemical equation of the and it gives us the idea of the molar concentration of the reactant and the products using the role of stoichiometry balancing reactions.
Step # 04:
In step 4, you need to find the atomic masses and the molar masses of the reactant and the products. The number of moles is going to be multiplied by the atomic masses of the reactant and product. So, it makes it possible to find the number of grams of the reactant.
According to the laws of the conservation of the masses, the same amount or the quality of the product is produced. Moreover, you can use the stoichiometry calculator to find the quality of the reactants the products in a chemical reaction.
Now the chemical reaction of the iron oxide Fe2O3 occurs when 4 moles of the iron react with three moles of oxygen, it produces 2 moles of the iron oxide.
You can write the molar concentration in grams as the role of stoichiometry balancing reactions.
- 4 moles of the iron = 4(26) =104 grams.
- 3moles of the Oxygen = 3(16*2) =96grams.
- 2 moles of the Iron Oxide=Fe2O3 = 2[2(26)+3(16)] =204 grams of Fe2O3
It means that 104 grams of the iron are going to react with the 96 grams of Oxygen. There would be 204 grams of Iron oxide is going to be produced.
The stoichiometric assist to find the molar masses of the reactant and the product in a chemical reaction. When you are able to balance the molar masses, you can get the atomic masses of the reactants and the products. In conclusion, the above example, you have observed the reactant react in a given proportionality.
