What is the substance present at the start of a reaction?
The substance present at the start of a chemical reaction is called a reactant. Reactants are the starting materials that undergo chemical changes to form products during a reaction.
What is a chemical reaction and how are reactants and products involved?
A chemical reaction is a change in which one kind of matter changes into a different kind of matter with different properties. Reactant is a substance used in a chemical reaction and a product is a substance made in a chemical reaction. Hope this is helpful! ;)
How is a chemical property different from a physical property?
A chemical property describes how a substance reacts or changes to form a new substance, such as flammability or reactivity. A physical property, on the other hand, describes characteristics of a substance that can be observed or measured without changing its identity, such as color, density, or melting point.
It reacts with hydrogen to form a gas. Is it a chemical or physical property of sulfur?
It is a chemical property of sulfur because it involves a reaction with another substance to form a new compound. Chemical properties describe how a substance can undergo chemical changes to form new substances.
Is magnesium burning a physical change?
No, magnesium burning is a chemical change because the magnesium undergoes a chemical reaction with oxygen to form magnesium oxide. Physical changes do not alter the chemical composition of a substance, whereas chemical changes do.
What changes when the amount of a substance changes?
When the amount of a substance changes, it can affect the concentration, density, and reactivity of the substance. In chemical reactions, changing the amount of a substance can also impact the equilibrium position and the rate of reaction. Additionally, changing the amount of a substance can influence its physical properties, such as melting point, boiling point, and solubility.
When a substance changes into another substance with other properties?
This is a typical chemical reaction.
What is the diffence between physical and chemical properties as well an physical and chemical changes?
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
Differences between physical changes and chemical changes?
Physical changes are changes that affect the form of a chemical substance, such as changes in state or shape, without changing its chemical composition. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.
When a substance changes from one physical form to another you say the substance had had an?
Chemical reaction
Is reactivity a physical change?
Reactivity is a chemical property, not a physical change. It refers to the ability of a substance to undergo a chemical reaction with another substance. Physical changes involve alterations in the form or state of a substance without changing its chemical composition.
What is the substance that changes the rate of chemical reactions without being changed called?
A substance that changes the rate of a chemical reaction without being consumed is called a catalyst. Catalysts work by lowering the activation energy required for the reaction to occur, thereby speeding up the reaction process.
What is a chemical reaction and how are reaction and products involved?
A chemical reaction is a change in which one kind of matter changes into a different kind of matter with different properties. Reactant is a substance used in a chemical reaction and a product is a substance made in a chemical reaction. Hope this is helpful! ;)
What is changes of chemistry?
Changes in chemistry refer to alterations in the properties and composition of substances as a result of chemical reactions. These changes can be classified as physical changes, where the substance's form is altered without changing its composition, or chemical changes, where new substances are formed. Understanding these changes is fundamental to understanding the behavior of matter in various environments.
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 chemical reaction and how are reactants and products involved?
A chemical reaction is a change in which one kind of matter changes into a different kind of matter with different properties. Reactant is a substance used in a chemical reaction and a product is a substance made in a chemical reaction. Hope this is helpful! ;)
What is a reactant?
A reactant is a substance that participates in and changes during a reaction.
