in chemical reaction; mass is equal at the beginning and at the end...
you may need to know stecheometry concepts for example
1NaOH + 1HCl ------> 1NaCl+ 1H20
W 40g + 36.5g ------> 58.5g + 18 g
W 76.5g-------------> 76.5g
Na=23
Cl=35.5
H=1
O=16
hope to be helpfull to you

Is this chemical equation considered a combustion reaction and if yes why 4Na plus O2 equals 2NaO2?
4Na+O2=2Na2O? That must be the equation... Im not sure what you're asking... But, in a combustion reaction, something reacts with oxygen gas (O2). In this equation sodium is reacting with oxygen... So, yes, this is a combustion reaction.
Which three terms could be used to identify the carbon C in this chemical equation C plus O2 equals CO2?
element product atom
5cm equals how many dm?
5cm equals 0.5dm
What equals 572 cups equals how many quarts?

How many milligram equals a gram?
1000 milligram equals a gram
What represents the correct way to write a chemical equation reactants--products products equals reactants reactants equals sum sum--- reactants?
reactants ---> products
Who experimented with chemical reactions and discovered that the mass of the reactants before a chemical reaction equals the mass of the products afterward?
Joseph proust
What represents the correct way to write a chemical equation reactants ----- products products equals reactants reactants equals sum sum ---- reactants?
reactants -----> products is correct
What is always true of chemical reactions?
the total mass of the reactants equals the total mass of the products
What does it mean if Keq equals 1?
Products and reactions are equally favored in the reactions
In a chemical reaction the mass of the products is what?
The Mass of Products equals the Mass of the Reactants. "Nothing is created or destroyed - The Law of Conservation of Energy - Many reactions like fires (combustion) gases escape and thus the reactants appear to lose Mass. However, if all gases are collected and weighed the Mass of the Products will equal the mass of the Reactants
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.
Why can you not use an equals sign for a chemical equation?
Chemical equations have frequently an equal sign (=) between reactants and products.
In a balanced chemical reaction the total mass of the products always equals the total what?
In a balanced chemical reaction the total mass of the products always equals the total mass of reactants; this is the law of mass conservation.
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 chemical reaction occur when acids are mixed with bases?
The mass of products equals the mass of reactants.
How does the mass of the products in a chemical equation compare to the mass of a reaction?
In a closed system, the mass of the products equals the mass of the reactants.
