What substance is always made in a chemical reaction?
Reactants
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
What is always involved when physical or chemical changes occur in matter?
Energy is ALWAYS invoved.
What always happens to the atoms within molecules undergoing a chemical reaction?
In a chemical reaction sometimes old bonds are broken and new bonds are formed.
What is the difference between the predicted and actual yield in a chemical reaction?
The actual yield of a reaction product is always less than the yield from the chemical equation. This is because of error.
Is boiling always a sign of a chemical reaction?
No, boiling is not always a sign of a chemical reaction.
Chemical Reactions always involved changes in chemical?
Yes. The chemicals (reactants) that undergo a chemical reaction react with each other and make new chemicals called the products.
What is always involved in physical or chemical change in matter?
Energy is always involved.
What part of the atom is involved in a chemical bond?
A standard chemical reaction always and only involves a change in the electron configuration of the atom (either the number of electrons or their energy configuration).If the nucleus is affected (either the number of protons or electrons), then it is designated as a nuclear reaction, and this is quite different.
Why must chemical equations always balance what is the law?
The fundamental law is that 'matter can neither be created or destroyed in a chemical reaction'. This means that there has to be the same amount of matter on either side of the chemical equation, arranged differently, but the same number of atoms of each element involved in the reaction.
Is burning of fuel in a cutting torch a chemical reaction?
Yes, burning of fuel is always a chemical reaction.
What is always conserved in a chemical reaction?
mass
What changes are always involved in chemical reactions?
electrons are always involved in chemical reactions. how they are positioned which atom they are located if they are sharing paired unpaired etc.
What is always formed during a chemical reaction?
a chemical reaction always converts reactants to products. Products are always formed otherwise it's not considered a chemical reaction.
What substance is always made in a chemical reaction?
Reactants
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.
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
