What else can I help you with?
When substances go through a chemical change is mass always gained or lost or conserved?
The mass remain unchanged; this is the law of mass conservation.
Does a chemical equation show the number of atoms lost during a chemical reaction?
Yes, a chemical equation shows the number of atoms of each element involved in a chemical reaction, including those gained, lost, or rearranged. The Law of Conservation of Mass states that mass is conserved in a chemical reaction, so the total number of atoms before and after the reaction must be the same.
Why do reactions have to he balanced?
atoms are not lost or gained in a chemical reaction
Is mass conserved in methane?
Yes, mass is conserved in the combustion of methane. According to the law of conservation of mass, the total mass of reactants (methane and oxygen) equals the total mass of products (carbon dioxide and water) during the reaction. Although the form of the substances changes, no mass is lost or gained in the process.
What are never gained or lost in a chemical reaction?
matter is never destroyed by reactions created by chemical More specifically, both mass and energy cannot be created or destroyed in any chemical reaction, but mass and energy are equivalent under Einstein's theory of special relativity, so energy can change to mass and vice-versa in the ratio E = mc2
How does the of the conservative of mass apply to chemical reactions?
The law of conservation of mass states that in a close container, when a chemical reaction occurs, no mass will be lost.
How does the law of the conservation of mass apply to to chemical reactions?
Atoms cannot be added or lost in a chemical reaction.
When substances go through a chemical change is mass always gained or lost or conserved?
The mass remain unchanged; this is the law of mass conservation.
What happens to this lost mass?
Mass cannot be truly lost, as stated in the law of conservation of mass. It can change forms, such as being converted into energy through processes like nuclear reactions or chemical reactions. In these cases, the mass is not truly lost but rather transformed into a different state.
Does a chemical equation show the number of atoms lost during a chemical reaction?
Yes, a chemical equation shows the number of atoms of each element involved in a chemical reaction, including those gained, lost, or rearranged. The Law of Conservation of Mass states that mass is conserved in a chemical reaction, so the total number of atoms before and after the reaction must be the same.
Where did the 'lost mass' go during a chemical reaction?
False
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 would it mean if the change in mass is negative?
A negative change in mass means that the object has lost mass. It could be due to factors such as evaporation, chemical reactions, or loss of particles.
Why is is important to use a closed system when conducting experiments to determine the conservation of mass?
Using a closed system ensures that no mass is lost or gained from external sources during the experiment. This is important in determining the conservation of mass because any change in mass within the system can be attributed to the reactions taking place inside it, rather than external factors. It helps to accurately assess if mass is conserved in chemical reactions.
How does law of the conservation of mass apply to chemical reactions?
The Law of Conservation of Mass applies to chemical changes. When considering a chemical change this would mean that the total mass of all of the reactants in the chemical reaction is equal to the total mass of products in the chemical reaction.
In a nuclear reaction mass must be lost to produce energy. true or false?
False. Both mass and energy are conserved.
What is matter in a chemical process its not lost nor gained?
In a chemical process, matter is not lost nor gained; it is simply rearranged into new combinations. This is known as the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction, only converted into different forms.
