What three ways would let you know that a reaction had taken place?
Changes in color: If the color of the reactants or products changes during the reaction, it is a sign that a chemical reaction has occurred. Formation of a gas: Production of gas bubbles or fizzing indicates a chemical reaction, such as in the reaction between an acid and a carbonate. Changes in temperature: If the reaction absorbs or releases heat, causing a change in temperature in the surroundings, it signals a chemical reaction has taken place.
What are 3 ways you know a chemical change has taken place?
Three signs of a chemical reaction include the release or absorption of heat, a change in color, and the creation of a gas or a precipitate.
What is always present for a combustion reaction to occur?
For a combustion reaction to occur, three things are required: fuel (such as gas or wood), oxygen (usually from the air), and a source of heat (spark or flame) to initiate the reaction. Without any of these three components, combustion cannot take place.
What are three ways to recognize if a Single Displacement reaction has taken pace?
Explain why a 16th century coin could remain glistening under the sea after hundredds of years
What three elements are necessary for combution to take place?
The three elements necessary for combustion to take place are fuel, oxygen, and heat. Fuel provides the substance to burn, oxygen is needed for the reaction to occur, and heat is necessary to initiate the combustion process.
What three substances are made when a reaction between a metal carbonate and acid takes place?
Example: CaCO3 + 2HCl = CaCl2 + CO2 + H2O

What are three way to recognize if a single displacement reaction has taken place?
Observation of a change in color: If there is a noticeable color change in the reactants or products of the reaction, it may indicate a single displacement reaction. Formation of a precipitate: If an insoluble solid (precipitate) forms when two aqueous solutions are mixed, it is likely a single displacement reaction. Evolution of gas: If there is bubbling or fizzing observed when two substances are mixed, it could suggest a single displacement reaction has occurred.
Can you list three kinds of changes that indicate a chemical reaction has taken place?
Some signs that a chemical change has taken place is that a gas can be produced, the temperature can change, and a substance disappears. Other signs are that a solid is formed, the color changes, and a new odor is produced.
What is oedipus reaction to hearing that laios was killed in a place where three highways met?
He remembers that he had killed someone at the same place.
What is oedipus's reaction to hearing that Laios was killed in a place where three highways met?
He remembers that he had killed someone at the same place.
What is the three-dimensional part of an enzyme molecule where the reaction takes place?
The active site of an enzyme is the three-dimensional part of the enzyme molecule where the catalytic reaction takes place. It is a specific region that binds to the substrate and facilitates the chemical reaction to occur. The active site provides a suitable environment for the reaction to proceed efficiently.
What kind of reaction is metal oxide plus nonmetal oxide æ ternary salt?
Reaction between a metal oxide and a nonmetal oxide to produce a salt containing at least three elements is a synthesis reaction. The salt almost always contains at least one monatomic metal cation and at least one polyatomic anion that contains all of the elements of the reacted nonmetal oxide plus the oxygen atoms from the metal oxide. This type of anion is called an "oxyanion" or the "anion of an oxyacid."
What is the chemical reaction for the formation of rubber?
The type of chemical reaction that takes place through the formation of the rubber is called the mechano-chemical reaction. Through this, it gives the end product a three dimensional structure.
What is a ternary salt from reaction of metal oxide with nonmetal oxide?
A ternary salt results from the reaction of a metal oxide with a nonmetal oxide by combining one cation from the metal oxide with one anion from the nonmetal oxide, forming a compound with three different elements. An example is sodium nitrate (NaNO3) produced from the reaction of sodium oxide (Na2O) with nitrogen dioxide (NO2).
What kind of reaction is metal oxide nonmetal oxide æ ternary salt?
Reaction between a metal oxide and a nonmetal oxide to produce a salt containing at least three elements is a synthesis reaction. The salt almost always contains at least one monatomic metal cation and at least one polyatomic anion that contains all of the elements of the reacted nonmetal oxide plus the oxygen atoms from the metal oxide. This type of anion is called an "oxyanion" or the "anion of an oxyacid."
