Which indicates that a reaction has occurred after one substances has been added to another?
The appearance of a color change, formation of a precipitate, evolution of gas, or change in temperature are common indications that a reaction has occurred when one substance is added to another. These observable changes often signal a chemical reaction taking place between the reactants.

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).
What is the appropriate definition for chemical reaction in terms of science?
A chemical reaction is a process that results in the transformation of one set of chemical substances into another. It involves the breaking and forming of chemical bonds, leading to the creation of new substances with different properties.
What other name does chemical change have?
Chemical change is also known as a chemical reaction, where substances interact and form new substances through the breaking and forming of chemical bonds.
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.
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 can infer that the two original substances in the mixture must have properties that react with water to produce the green and orange colors when exposed to it. This observation suggests a chemical reaction might have occurred between the substances and the water.
What is the chemical reaction that combines two or more substances to produce another substance?
A synthesis reaction

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.
The change that takes place when two or more substances interact to form new substances is called a 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.
What is another term for chemical change?
A chemical change is also referred to as a chemical reaction. It typically involves the transformation of substances into new substances with different chemical compositions.
What is it called when two or more substances combine to form another substance?
a synthesis reaction
