What law is used to describe a balanced equation?
Law of conservation of masses.
How does a balanced chemical equation show that mass is never lost or gained in a chemical reaction?
Because the Balanced equation can correctly add the reactants and it will equal the sum of the products.If a chemical equation is balanced correctly, there will be the same number of each element on both sides. Since each element has a given and known mass, the total mass on each side of the balanced equation must be equal.
What conditions must be satisfied by a balanced chemical equation?
It should have equal no. of atoms of different elements in the reactants and products. It should have equal masses of various elements in reactants and products.
What is stoichiomerty?
Stoichiometry is a branch of chemistry that deals with the quantitative relationships between the amounts of reactants and products in a chemical reaction. It allows us to understand and predict the amount of substances involved in a reaction, based on the balanced chemical equation. In stoichiometry, the coefficients in a balanced chemical equation represent the mole ratios between the different reactants and products. These coefficients indicate the relative number of molecules, atoms, or moles of each substance involved in the reaction. Stoichiometry calculations involve converting between the mass, moles, or volume of substances participating in a reaction using the stoichiometric ratios provided by the balanced equation. This allows us to determine the amount of reactants needed, the amount of products formed, and to predict the limiting reactant or the excess reactant in a reaction. Stoichiometry calculations can be used to answer questions such as: How much product can be obtained from a given amount of reactant? What mass of reactant is required to produce a specific amount of product? How much of one reactant is needed to completely react with another reactant? What is the stoichiometric ratio between reactants and products in a chemical reaction? Stoichiometry is an essential tool in chemical analysis, synthesis, and understanding the quantitative aspects of chemical reactions. It allows chemists to design and optimize reactions, determine reaction yields, and ensure efficient use of reactants.
Why must all chemical reactions be balanced?
All chemical reactions must be balanced, because matter is neither created nor destroyed in these reactions. Even if the arrangement of the individual atoms is different, the number of atoms of each element remains constant. Note that chemical reactions differ from nuclear reactions.
What law is used to describe a balanced equation?
Law of conservation of masses.
What does stoichiometric mean in chemistry?
Stoichiometric refers to the ratio of reactants in a chemical reaction that ensures complete consumption with no excess. It is based on the molar quantities of substances involved in a balanced chemical equation. A stoichiometric amount of reactants results in maximum product formation.

What is the theoretical yield of ethanol?
This question cannot be answered as written. The chemical equation is needed, as well as the masses of the reactants.
Use the following balanced chemical equation to calculate the mass of carbon dioxide produced from the burning of 3.73 kg of jet fuel which can be represented by the molecule C12H26 You?
calculate the masses first then apply the ratios & then multiply by the mass gives answer of 11Kg to 2 sig figs
A chemical reaction is balanced by changing?
To balance a chemical equation, you can change the coefficients (number of molecules). Remember: You cannot change the subscripts.When we balance an equation we change the number of atoms on one or both sides of the equation by means of simple mathematical calculation. That is, we change the number of molecules of one or more reactants or products. When the number of atoms of each element is equal on both sides of the equation, and cannot be reduced equally, the balancing process is complete.
Does the law of conservation of mass satisified in beta decay process?
The masses don't exactly balance. Instead, the energy of the whole system is balanced (remember mass and energy are related by the equation E = mc^2)
If you know the molar masses of the reactants in a chemical reaction can you determine the molar masses of the products?
If you know know the molar masses of the reactants in a chemical reaction you can determine the molar masses of the products because the combined molar masses of the reactants equals the combined molar masses of the products.
Which Russian scientist related chemical properties and atomic masses?
Dmitri mendeleev related the chemical properties and atomic masses around 1860
After a chemical reaction starts when will a chemical reaction end?
When the limiting reactant is completely used up. A limiting reactant is the reactant that determines the amount of product. To determine this use the balanced chemical reaction with the masses of the reactants to determine the moles of product formed. The reactant that forms the least amount of product will be the limiting reactant.
What are some balanced equation?
In terms of Chemistry, such equation which obeys the law of conservation of mass are balanced equations since the mass is the same on both the reactants and the product side. In simple words the no. of atoms on both sides are the same making the sum of the atomic masses the same too. Like in the equation: CH4 + 2O2 --------------------> CO2 + 2H2O notice that there is only one carbon on both sides, 4 hydrogen atoms and 4 oxygen atoms on both sides. If we sum their atomic masses it will be equal to 80 on both the reactant and the product side satisfying the "Law of Conservation of Mass" which says the initial and final weight of the system remains the same.
