Is a chemical reaction?
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.
When two or more substances combine in a chemical reaction to form another substance a blank reaction is taking place?
Reactants
Why are precipitation reactions also called double displacement reactions?
They aren't. Double displacement (metathesis) sometimes forms a precipitate, but not always, and it would be silly to call it a "precipitation reaction" if no precipitate was formed. Formation of a precipitate is, however, one way to tell that a reaction has occurred. If everything just stays in solution, then it's meaningless to call it a "reaction" since there has been no change. The evolution of a gas is another method for determining that a reaction has occurred, as is a change in color (this often indicates a change in oxidation state as well, though not always).
If you mix to clear liquids together and bubbles for what type of change would this indicate?
It indicates a chemical reaction because it changes from one substance to another.
Define products in a chemical reaction?
They are substances formed by a chemical reaction. All atoms that are present in the reactants are present in the product. Products are always on the RIGHT of the formula.Exothermic reaction:Ex: Reactants--->Products + EnergyEndothermic reaction:Ex: Reactants+energy--> Products...Reactants...............Products{6CO2+6H2O}--->{C2H12O6+6O2 }
What type of reaction has occurred when two or more substance combine to form another substance?
This is called synthesis, a combination chemical reaction that changes the chemical bonds in the substances.
What is the chemical reaction that combines two or more substances to produce another substance?
A synthesis reaction

The change that takes place when two or more substances interact to form new substances is called a reaction.?
two
What type of reaction has occured when two or more substances combine to form another substance?
This is called synthesis, a combination chemical reaction that changes the chemical bonds in the substances.
What reaction has occurred when one element replaces another in a compound?
This kind of reaction is usually called a "single displacement" or :single replacement" reaction.
Is the change that takes place when two or more substances interact to form new substances.?
A chemical reaction is the change that takes place when different substances react with one another to form new substances. The substances that react in a chemical reaction are called the reactants and the new substances formed are called the products.
When two or more substances combine in a chemical reaction to form another substance a blank reaction is taking place?
Reactants

Ty added water to a mixture of two other substances. A short time later the observed that one substance had turned green and another had turned orange What might Ty infer?
Ty should conclude that a chemical reaction has taken place. Change of color is a typical sign that a chemical reaction has occurred.
