To predict the mass of a reactant or product in a chemical reaction, you would need the balanced chemical equation for the reaction, as it provides the stoichiometric ratio between the reactants and products. Additionally, you would need the molar mass of the specific substance you are interested in. With this information, you can calculate the mass using stoichiometry and molar ratios.

What determines the coefficient ratio used to predict the amount of product produced from any given amount of reactant?
The reaction equation gives the RATIO of moles reactant to moles product. With known molar mass the (mass) yield can be calculated. (Of course other reactants are to be in excess! for complete reaction of the reactant involved for this yield)
What information is used to predict chemical reactivity?
The electronegativity of the elements help this prediction.
What is the difference between a math equation and a chemical equation?
A math equation uses variables and numbers, while a chemical equation uses compounds and mole ratios.
What type of subject does thermochemistry deal with?
Thermochemistry is the study of energy and heat dealing with chemical reactions as well as physical differences that occur when this chemical reaction takes place. Thermochemistry is used to predict what weather conditions are going to be.
How can you use an activity series of elements to predict whether a given reaction will occur and what the products will be?
An activity series is used to predict whether metals will displace hydrogen gas from water and acid solutions. It is also used to predict whether metals will displace other metals.
When can you predict the reactant in a decomposition reaction?
The reactant is chosen by you; also the study of products of the reaction give information about the initial compound.
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 is it important to learn about chemical elements?
In chemistry it is very important to understand the properties of elements in order to predict their effects on other elements and compounds during chemical reactions. This information can be used to formulate a hypothesis for a reaction, or better understand the chemical processes that may have occurred in a reaction.
Why is limiting reactants important in stoichiometry?
Limiting reactants are the reactants that are used up first. And once they are used up, they stop, or limit, the reaction. So the amount of product that can be produced depends on the limiting reactant. The other reactant, the one in excess, would predict a larger amount of product. But once we produce the amount of product predicted by the limiting reactant. The limiting reactant is used up and the reaction stops.
What information is used to predict chemical reactivity?
The electronegativity of the elements help this prediction.
What is the purpose of writing a word equation in chemistry?
It is one way of representing a chemical reaction: it tells you what reacts and what is produced. Word equations are an efficient way to describe chemical changes, to help chemists recognize patterns, and to predict the products of a chemical reaction.
How was Dalton able to predict the information of multiple compounds between the elements?
Only after experiments and determination of the chemical composition.
Predict the products for the reaction between Cu3PO4 and KMnO4?
KMnO4 + C3H8O3 => K2CO3 + H2O + CO2 + MnO2
Why does chemist study energy?
Because without the knowledge of energy a chemist can not predict either the specific chemical reaction is possible or not, he can also predict that which fuel is better for a specific Vachel and several other factors may be predicted.
