Are the masses of products and reactants always equal?
Yes, in a chemical reaction matter (mass) can not be crated or destroyed).
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.
In a chemical reaction how does the total mass of the reactants compare to the total mass of the products?
The mass of the reactants compare to the mass of the products in that they are equal. The law to conservation of mass states that mass cannot be createdor destroyed. It can only be altered which would be a case in a chemical reaction.
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.
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.
What if the total mass of the product in a chemical reaction is 14grams what must the combined masses of the reactants be?
The mass of reactants is equal to the mass of products.
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.
Are the masses of products and reactants always equal?
Yes, in a chemical reaction matter (mass) can not be crated or destroyed).
What happens to mass when substances go through a chemical change?
The total mass of products is unchanged from the total mass of the reactants, but the masses of particular substances among the reactants or products change.
How do you calculate the masses of chemical reactants and products in a chemical reaction?
The term used to describe the calculation of the quantities of reactants and products in a chemical reaction is stoichemistry. It is the calculation of quantitative (measurable) relationships of the reactants and products in a balanced chemical reaction.
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.
In a chemical reaction how does the total mass of the reactants compare to the total mass of the products?
The mass of the reactants compare to the mass of the products in that they are equal. The law to conservation of mass states that mass cannot be createdor destroyed. It can only be altered which would be a case in a chemical reaction.
During a chemical reaction the total amount of mass present?
The sum of the masses of the reactants and the masses of the resulting substances, at a specified moment.
How do the force factors compare to the products of the masses?
Mass can neither be created or destroyed in a chemical reaction, so there is a requirement that the mass of all the reactants MUST equal that of the products.
What is the relationship between reactants and products in chemical reactions?
According to the Law of Conservation of Mass, in a chemical reaction, matter is neither created nor destroyed. Because of this the sum of the mass of the reactants will always equal the mass of the products.
What law is the mathematical relationship between the sum of the masses of the reactants and the sum of the masses of the products?
