Why physical states of reactants and products are mentioned while writing a chemical equation?
It is not obligatory but it is important as indication for other chemists or students.
How do you write a balanced chemical equation of copper2 oxide when copper metal is strongly heated in air including the physical states of the reactants and products?
Cu (s) + O2 (gas) -------> Cu O2 (aq)
Which is a characteristic of chemical equilibrium but not physical equilibrium?
the reactants and products are different substances
What are some examples of the law of conservation of mass?
The Law of Conservation of Mass states that "In a physical process there is no change in composition of matter and the state of matter alone changes." Examples of these in daily life are the melting of ice and the boiling of water.
What physical characteristics allow you to identify in a salt the presence of an ion of a transition metal?
Reactants and solutions
What tells reactants products physical state and proportions of each substance in a chemical reaction?
A chemical equation

Which is chemical equation?
A chemical Equation is a shorthand form of a chemical reaction. chemists use it to help them tell the substances that are present such as reactants, products, or proportions.Some equations also tell the physical state of a substance.
How do reactants and products and compar before and after a chemical reactgion?
The products have different physical and chemical properties than the reactants.
How do you write a balanced chemical equation of copper2 oxide when copper metal is strongly heated in air including the physical states of the reactants and products?
Cu (s) + O2 (gas) -------> Cu O2 (aq)
What symbolic representation of a chemical reaction?
There are several things that may symbolize a chemical reaction. One of the main symbols is a chemical equation which will represent the entities in the reaction. .
In what system can reactants exist in different physical states?
heterogenous equilibrium
In what system can reactants exist in the same physical states?
Heterogeneous Equilibrium
What term is defined as mathematical euations based on rules of physics?
That would probably be something like a "physical equation".That would probably be something like a "physical equation".That would probably be something like a "physical equation".That would probably be something like a "physical equation".
In a heterogeneous equilibrium system the reactants and products exist in what?
Different physical states
Which is a characteristic of chemical equilibrium but not physical equilibrium?
the reactants and products are different substances
What does a chemical reaction show?
It shows the preservation of mass and of matter.
