What is an indicator of a chemical reaction?
A visible change in color, formation of a precipitate, evolution of gas, or change in temperature are indicators of a chemical reaction. These changes typically signify that the chemical composition of the substances involved in the reaction has been altered.
What happens to total amount of mass in chemical reaction?
The total amount of mass remains constant in a chemical reaction, according to the law of conservation of mass. This means that the total mass of the reactants will equal the total mass of the products formed in the reaction. Mass cannot be created or destroyed in a chemical reaction, only rearranged.
Does the conservation of mass change if a chemical change occurs?
No, the conservation of mass states that mass is neither created nor destroyed in a chemical reaction. The total mass of the reactants must equal the total mass of the products, regardless of the type of reaction occurring.
What statement that is a correct expression of the law of conservation of mass?
The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction, it can only change forms. This means that the total mass of the reactants must be equal to the total mass of the products in a chemical reaction.
If the mass of all objects before a chemical change is 200kg what would the mass be after the chemical changed occurred?
There will be a gain in mass.....but you can't predict the new change in mass unless you weigh the products after the chemical change occurred.
Why isn't a change in mass an indicator of chemical change?
Neither a chemical nor a physical change results in a change in mass. According to the law of conservation of matter/mass, matter can neither be created nor destroyed. This law holds true for physical and chemical changes.
What is an indicator of a chemical reaction?
A visible change in color, formation of a precipitate, evolution of gas, or change in temperature are indicators of a chemical reaction. These changes typically signify that the chemical composition of the substances involved in the reaction has been altered.
What undergoes no chemical change during a chemical reaction?
A catalyst undergoes no chemical change during a chemical reaction.
Which observation does not indicate that a chemical reaction has occured?
A change in state, such as boiling or melting, does not always indicate a chemical reaction has occurred. It could be a physical change.
What happens to total amount of mass in chemical reaction?
The total amount of mass remains constant in a chemical reaction, according to the law of conservation of mass. This means that the total mass of the reactants will equal the total mass of the products formed in the reaction. Mass cannot be created or destroyed in a chemical reaction, only rearranged.
Does the conservation of mass change if a chemical change occurs?
No, the conservation of mass states that mass is neither created nor destroyed in a chemical reaction. The total mass of the reactants must equal the total mass of the products, regardless of the type of reaction occurring.
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.
What does not happen in a chemical reaction?
In a chemical reaction, the total mass of the reactants should be equal to the total mass of the products formed (law of conservation of mass). This means that mass is neither created nor destroyed during a chemical reaction.
will a catalyst change the enthalpy of a reaction in a chemical reaction?
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
What statement that is a correct expression of the law of conservation of mass?
The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction, it can only change forms. This means that the total mass of the reactants must be equal to the total mass of the products in a chemical reaction.
If the mass of all objects before a chemical change is 200kg what would the mass be after the chemical changed occurred?
There will be a gain in mass.....but you can't predict the new change in mass unless you weigh the products after the chemical change occurred.
Which is supported by the law of conservation of mass?
During a chemical reaction, the total mass of the system cannot change.
