The Stoichiometry Is the part of chemistry that studies the amounts of substances involved in the reactions. With the Stoichiometry You can know what the substances are like before and how they will be after the chemical reaction.
All reactions depend on the amount of things they have. Stoichiometry helps you determine the amount or proportion of compounds you will need in a chemical reaction.
Stoichiometry is present in daily life, even in the cooking recipes we make at home.
The reactions depend on the compounds involved and how much of each compound is needed to determine the product that will result.
The elements that are taken into account in the stoichiometry are: mass of reagents (chemicals before the reaction); Mass of products (chemicals after the reaction); Chemical equations; Molecular weights of reactants and products and formulas of various compounds.
Examples of stoichiometry in life would say
1) Cooking Recipes
Most people love cookies. In this case, stoichiometry helps us in the following way;
If you want to make 10 cookies, the chemical"equation"of the mass of reagents (chemicals before the reaction) would be:
200 grams of flour + 2 eggs + 200 grams of butter + 1 cup of sugar = 10 cookies.
But, it turns out that the mass of reagent you have, or rather the ingredients, are incomplete because you only have one egg. A new chemical equation is made, where everything is cut in half to achieve a result:
100 grams of flour + 1 egg + 100 grams of butter + 1/2 cup of sugar = 5 cookies.
The 5 cookies would be the mass of products (chemicals after the reaction), that is, the result of the union of the ingredients through a chemical equation.
2) Safety in cars
Today automobiles are the main means of transportation of people anywhere in the world.
For cars to be safer, car companies placed airbags in the steering wheel and other places inside the vehicle to protect people in the event of a collision.
With stoichiometry you can know how much nitrogen gas must be produced in a matter of seconds for the bag to inflate by impact and can save the life of the driver or passengers. Applications of means of transportation of the person in any part of the world. St
3) Help not to get lost
At present it is normal for people to be located by their GPS to get an address or know if they have a shop or bank near them. This localization system is composed of several satellites in space.
Stoichiometry helps calculate the fuel, weight and materials needed for rockets to fly into space to leave satellites in orbit. In addition, it calculates the fuel and reaction of the satellite components in orbit.
Thus we can enjoy a global positioning system so that we do not get lost.
With these simple examples, you can see how daily life is filled with many more scientific elements than we know.
