Is momentum conserved in inelastic collision?
The energy of the momentum in a collision is conserved through the following occurrences; movement of vehicle(s) after impact, deformation of the vehicle(s) or objects hit, heat and sound.
Which scientist showed that the total mass of the substances in a chemical reaction is always the same before and after the chemical reaction?
Antoine Lavoisier
Is a mixture always a chemical combining of substances?
Any particular isolated sample of a mixture has a definite chemical composition, but the general idea of a mixture, even of the same materials, implies variability in possible chemical composition.
Is total electric charge conserved in electron capture?
Yes. Total electric charge is always conserved. No exceptions are known.
What happens to a substance during a chemical change or chemical reaction?
substances can change to a solid, gas or liquid. solid - precipitate gas - fumes liquid - color change Either way, since its a chemical reaction, there always will be a change in the chemical composistion of a substance.
What is always conserved in a chemical reaction?
mass
When matter changes state what two things are always conserved?
Mass and chemical composition
Why is mass conserved during the combution of methane?
Its conserved during the combustion of anything - the mass of the products is always equal to the mass of the materials that react.
How does a chemical equation show that matter is always conserved in a chemical reaction?
According to the Law of Conservation Of Mass,Matter is neither created nor destroyed.It means a chemical equation show that matter is always conserved in a chemical reaction.It is shown as number of atoms both sides of the reaction before and after remains the same.
What is example of Energy conservation?
Any physical or chemical process will serve as an example, since energy is always conserved.Any physical or chemical process will serve as an example, since energy is always conserved.Any physical or chemical process will serve as an example, since energy is always conserved.Any physical or chemical process will serve as an example, since energy is always conserved.
When a chemical property is observed the identity of the substances?
Always :)
When momentum can be conserved?
Momentum is always conserved. No matter what the collision, as long as you look at everything involved, momentum will always be conserved.
New substances are always formed when matter undergoes?
chemical change.
Is machanical energy always conserved?
No. Total energy is always conserved, but not so mechanical energy.
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.
