Which element would you expect to gain one electron in a chemical reaction?
Metals are the elements that usually lose electrons in their chemical reactions. This is because they have few electrons in their outermost shells which are easily lost.
Why do reactions have to he balanced?
atoms are not lost or gained in a chemical reaction
Does a chemical equation show the number of atoms lost during a chemical reaction?
no
Is matter being lost when burning a log?
In a chemical reaction the mass of reactants is equal to the mass of products; burning is a chemical reaction.
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
Are electrons lost when a chemical reaction is a reduction?
Reduction Is Gain of electrons
Which element would you expect to gain one electron in a chemical reaction?
Metals are the elements that usually lose electrons in their chemical reactions. This is because they have few electrons in their outermost shells which are easily lost.
How many electrons are lost or gained in a chemical reaction?
There is zero NET loss or gain of electrons
Why do reactions have to he balanced?
atoms are not lost or gained in a chemical reaction
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.
What chemical equation shows that no atoms are lost during a chemical reaction?
This is a balanced chemical reaction.
This is not lost in a chemical reaction?
Mass can not be changed
Is hydrogen lost when a chemical reaction is a reduction?
NO
Does a chemical equation show the number of atoms lost during a chemical reaction?
no
Are valence electrons lost gained or shared during a chemical reaction?
They are lost.
What is never lost or created in a chemical reaction?
Matter and Energy
Is matter being lost when burning a log?
In a chemical reaction the mass of reactants is equal to the mass of products; burning is a chemical reaction.
