When substances are combined and no reaction occurs, it means that the substances are not capable of undergoing a chemical reaction with each other. This could be due to factors like the stability of the molecules, the absence of necessary reactants, or the lack of sufficient energy to drive a reaction. In these cases, the substances may simply mix together physically without forming any new chemical bonds.

What type of reaction occurs if two substances are chemically combined and there is a release of energy?
Exothermic
What a substances in a chemical reaction that are combined or separated to form new substances?
The substances in a chemical reaction that are combined are the reactants, and the substances that are formed as a result of the reaction are the products. Reactants are the starting materials, while products are the final end-products. Chemical reactions involve the breaking and forming of chemical bonds between atoms.
What happens When 2 or more substances combine chemically?
When two or more substances combine chemically, they undergo a chemical reaction where their atoms rearrange to form new chemical bonds. This results in the formation of one or more new substances with different properties than the original substances.
What is two or more substance only physically combined is what?
A mixture is when two or more substances are physically combined but can be separated by physical means, such as filtering or distillation. The substances in a mixture retain their individual properties and do not undergo a chemical reaction.
What is a chemical reaction with two or more substances combined to make a more complex compound?
synthesis

When two substances are combined and new substances are formed?
When two substances combine to form a new substance, it is said that a chemical reaction has occurred. This reaction is a combination reaction, also known as synthesis. The new substance formed may or may not possess the properties of the constituent substances.When the separate substances are elements, a chemical reaction is one that creates chemical bonds, the combined substance being a compound.
What happens When 2 or more substances combine chemically?
When two or more substances combine chemically, they undergo a chemical reaction where their atoms rearrange to form new chemical bonds. This results in the formation of one or more new substances with different properties than the original substances.
What is two or more substance only physically combined is what?
A mixture is when two or more substances are physically combined but can be separated by physical means, such as filtering or distillation. The substances in a mixture retain their individual properties and do not undergo a chemical reaction.
What is a chemical reaction with two or more substances combined to make a more complex compound?
synthesis
When two or more substances are combined the temperature of the reaction will?
When two or more substances are combined, the temperature of the reaction may increase or decrease depending on the specific reaction. This change in temperature is due to the release or absorption of energy during the chemical reaction.
What type reaction occurs when complex compounds are broken down into simpler substances?
This kind of reaction is called "decomposition".
What chemical reaction occurs when ammonium dichromate and mercury thiocyanate are combined?
When ammonium dichromate and mercury thiocyanate are combined, a chemical reaction called a decomposition reaction occurs. This reaction produces a visually striking effect known as the "Pharaoh's serpent" or "Pharaoh's snake," where a dark, coiling mass of solid material is formed.
What is the chemical reaction that occurs when salt and water are combined?
When salt is combined with water, a chemical reaction called dissolution occurs. This reaction involves the breaking of the ionic bonds in the salt crystals, causing the salt molecules to separate and disperse evenly throughout the water, creating a saltwater solution.
What is the original substances before a chemical reation occurs are the?
Reactants --> Chemical reaction --> Products
What type of reaction occurs complex compounds are broken down into simpler substances?
decomposition
