Matter cannot be created or destroyed, so there will be conservation of mass. If you look at a chemical equation, such as 2H2 + O2 = 2H2O, you can see that all the original material is there, just in a different arrangement. You start with 2 moles H2, which then get moved into H2O (typ. via combustion), and the same idea applies to the O2.
However, a very small amount of mass may be lost due to the energy change between products and reactants. This is a very small amount though, typically neglible.

What law of conservation says atoms are neither lost nor gained during a chemical reaction?
The law of conservation of mass states that in a chemical reaction, mass is neither created nor destroyed - it is conserved. This means that the total mass of reactants must equal the total mass of products in a chemical reaction.
During a chemical reaction the total amount of mass present?
During a chemical reaction, the total mass of the reactants is equal to the total mass of the products formed, according to the law of conservation of mass. This means that no mass is created or destroyed during a chemical reaction; it only changes form.
What makes up the mass in a chemical reaction?
In a chemical reaction, the mass is made up of the reactants and products involved in the reaction. According to the law of conservation of mass, mass is neither created nor destroyed during a chemical reaction, but is instead rearranged to form new substances.
What states that mass is neither created nor destroyed in chemical reaction?
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. This means that the total mass of the reactants before a reaction must equal the total mass of the products after the reaction.
Which scientific law predicts that the mass of the reactants before a chemical reaction will equal the mass of the products after the reaction has taken place?
The law of conservation of mass, also known as the principle of mass conservation or Lavoisier's principle, states that matter is neither created nor destroyed in a chemical reaction. This means that the total mass of the reactants must equal the total mass of the products in a closed system.
What does the law of conservation mass states that during a chemical reaction total mass is what?
The law of conservation of mass states that during a chemical reaction, the total mass of the reactants is equal to the total mass of the products formed. This means that mass is neither created nor destroyed in a chemical reaction, only rearranged.
What law of conservation says atoms are neither lost nor gained during a chemical reaction?
The law of conservation of mass states that in a chemical reaction, mass is neither created nor destroyed - it is conserved. This means that the total mass of reactants must equal the total mass of products in a chemical reaction.
What does the law of conservation of mass state that cannot be created or destroyed during a chemical reaction?
The law of conservation of mass (or matter) states that mass (or matter) cannot be created or destroyed during a chemical reaction. *Matter is anything that has mass and takes up space, so a lot of scientists call this the law of conservation of matter.
Which is supported by the law of conservation of mass?
During a chemical reaction, the total mass of the system cannot change.
According to the law of conservation of matter the number of is not changed by a chemical reaction.?
According to the law of conservation of matter, the total mass of substances before a chemical reaction is equal to the total mass after the reaction. This means that the number of atoms is not changed during a chemical reaction, only their arrangement.
What states that the reactants mass equals products mass?
The law of conservation of mass states that the total mass of the reactants in a chemical reaction is equal to the total mass of the products. This means that no mass is gained or lost during a chemical reaction, only rearranged.
The idea that atoms are gained nor lost during a chemical reaction is called the law of?
The idea that atoms are neither gained nor lost during a chemical reaction is called the law of conservation of mass. This principle states that the total mass of the reactants must equal the total mass of the products in a chemical reaction.
What does the law of conservation of mass tell about the mass of a reactants and products in a reaction before a chemical reaction and the ass of the products of the mass of products after a chemical?
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. This means that the total mass of the reactants before a chemical reaction is equal to the total mass of the products after the reaction. In other words, the mass of the reactants is the same as the mass of the products in a chemical reaction.
What is the principal stating that matter is not created or destroyed during a chemical reaction?
The Law of Conservation of Matter dictates that the mass of the reactants is equal to the mass of the products, i.e., mass will not be created, nor destroyed during the chemical reaction.
The mass of an atom increases or decreases during a chemical reaction?
The mass of an atom remains constant during a chemical reaction. According to the law of conservation of mass, mass cannot be created or destroyed, only rearranged. Therefore, the total mass of the atoms involved in a chemical reaction will remain the same before and after the reaction.
How would you use the word conservation of mass in a sentence?
how do you make a conservation of mass into a sentence
During a chemical reaction the total amount of mass present?
During a chemical reaction, the total mass of the reactants is equal to the total mass of the products formed, according to the law of conservation of mass. This means that no mass is created or destroyed during a chemical reaction; it only changes form.
