NO
This is a balanced chemical reaction.
Mass can not be changed
They are lost.
False
The amount of energy that is lost or gained by the products during the reaction.
Reduction Is Gain of electrons
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.
atoms are not lost or gained in a chemical reaction
This is a balanced chemical reaction.
It would be a positive ion, which is called an anion. (pronounced an-ion)
As I learnt it OIL RIG Oxidisation Is Loss (electrons are lost from the matter in question) Reduction Is Gain (the exact opposite electrons are gained from the matter in question)
Mass can not be changed
no
They are lost.
Mgnesium lost two electrons (reduction).
Matter and Energy
In a chemical reaction the mass of reactants is equal to the mass of products; burning is a chemical reaction.
