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

Why do reactions have to he balanced?
atoms are not lost or gained in a chemical reaction
How a balanced chemical equation really illustrate that mass is never lost or gained in a chemical reaction?
The kinds of atoms and the number of each kind are the same on both sides of a balanced chemical equation.
Elements can be lost or gain in chemical reaction?
Elements cannot be lost/gained: this is the law of mass conservation.
Number of electrons lost or gained by an atom in a chemical reaction is its?
Number of electrons are lost by an atom in a chemichl reaction
If matter is neither gained nor lost in a chemical reaction how did this or not do this illustrate the law of conservation of matter?
falaffles
What is gained in a chemical reaction?
Electrons are the ones gained or lost in a chemical reaction. Electrons are gained in oxidation and lost through the chemical reaction known as reduction.
Why do reactions have to he balanced?
atoms are not lost or gained in a chemical reaction
Are valence electrons lost gained or shared during a chemical reaction?
They are lost.
Mass can be lost or gained in a chemical reaction.?
False
What is the law of indestructibility of matter?
No weight is ever gained or lost in a chemical reaction.
How a balanced chemical equation really illustrate that mass is never lost or gained in a chemical reaction?
The kinds of atoms and the number of each kind are the same on both sides of a balanced chemical equation.

Number of electrons lost or gained by an atom in a chemical reaction is its?
Number of electrons are lost by an atom in a chemichl reaction
What is matter in a chemical process its not lost nor gained?
Mass is never lost nor gained - neither in chemical reactions, nor in other cases.
The enthalpy change for a chemical reaction exactly as it is written is what?
The amount of energy that is lost or gained by the products during the reaction.
How does a balanced chemical equations how that mass is never lost or gained in a chemical reaction?
if you balanced the equation correctly then the sum of the reactants will equal the sum of the the products because if there is the same amount of atoms on the reactants and the products obviously none is lost.
How many electrons are lost or gained in a chemical reaction?
There is zero NET loss or gain of electrons
