What are chemical reactions also known as?
Chemical reactions are also known as chemical changes because they involve the rearrangement of atoms to form new substances with different properties.
What is the difference between chemical reation and nuclear reation?
Chemical reactions involve the breaking and forming of chemical bonds between atoms to create new substances, while nuclear reactions involve the changes in the nucleus of an atom, resulting in the formation of different isotopes or elements. Chemical reactions typically involve changes in electron distribution, whereas nuclear reactions involve changes in the structure of the atom's nucleus. Additionally, nuclear reactions release much larger amounts of energy compared to chemical reactions.
Are chemical reactions a chemical change of original substances before a chemical reaction takes a place?
Chemical reactions involve the breaking and forming of chemical bonds in the original substances, resulting in a chemical change. Before a chemical reaction occurs, the original substances have specific chemical properties that undergo transformation during the reaction. The reactants interact to form new products with different chemical compositions.
What is the similarity between nuclear and chemical reaction?
Both nuclear and chemical reactions involve a change in the arrangement of atoms in a substance, resulting in the formation of new products. Additionally, both types of reactions involve the release or absorption of energy in the form of heat or light.
What is always true of chemical reactions?
Chemical reactions involve the breaking and forming of chemical bonds, resulting in the rearrangement of atoms to form new substances. The total mass of the substances before a chemical reaction is equal to the total mass of the substances after the reaction, as dictated by the law of conservation of mass.
Do chemical reactions make new substances?
Yes, chemical reactions involve the breaking and formation of chemical bonds, resulting in the formation of new substances with different properties than the original reactants.
What are three categories of chemical reactions?
The three categories of chemical reactions are synthesis (combination), decomposition, and replacement (single or double displacement) reactions. Synthesis reactions involve the combination of two or more substances to form a new compound. Decomposition reactions involve the breakdown of a compound into simpler substances. Replacement reactions involve the exchange of ions between compounds.
What chemical reactions involve two main kinds of changes?
formation of new substances!!
Is reactions a chemical or physical?
Reactions can be both chemical and physical. Chemical reactions involve breaking and forming chemical bonds leading to the formation of new substances. Physical reactions involve changes in state, shape, or form of a substance without changing its chemical composition.
What are chemical reactions also known as?
Chemical reactions are also known as chemical changes because they involve the rearrangement of atoms to form new substances with different properties.
What is the difference between chemical reation and nuclear reation?
Chemical reactions involve the breaking and forming of chemical bonds between atoms to create new substances, while nuclear reactions involve the changes in the nucleus of an atom, resulting in the formation of different isotopes or elements. Chemical reactions typically involve changes in electron distribution, whereas nuclear reactions involve changes in the structure of the atom's nucleus. Additionally, nuclear reactions release much larger amounts of energy compared to chemical reactions.
What transfers do all chemical reactions involve?
All chemical reactions involve the transfer of electrons between atoms or molecules. This transfer of electrons can result in the formation of new chemical bonds, breaking of existing bonds, and the rearrangement of atoms to form new substances.
Chemical reactions always involve changes in a chemical?
There will always be changes in one of the reactants. In some chemical reactions, one of the chemicals works as a catalyst to encourage a reaction between two or more chemicals but does not change during the reaction.
Are chemical reactions a chemical change of original substances before a chemical reaction takes a place?
Chemical reactions involve the breaking and forming of chemical bonds in the original substances, resulting in a chemical change. Before a chemical reaction occurs, the original substances have specific chemical properties that undergo transformation during the reaction. The reactants interact to form new products with different chemical compositions.
What is the similarity between nuclear and chemical reaction?
Both nuclear and chemical reactions involve a change in the arrangement of atoms in a substance, resulting in the formation of new products. Additionally, both types of reactions involve the release or absorption of energy in the form of heat or light.
Do chemical reactions have starting substances that collide with each other?
Yes, chemical reactions typically involve reactant molecules colliding with each other in order to undergo a change in chemical structure. These collisions provide the necessary activation energy for the reaction to proceed.
Is weight a chemical property or chemical reaction?
Weight is not a chemical property or chemical reaction. Weight is a measurement of the force of gravity acting on an object and is a physical property. Chemical properties describe how a substance interacts with other substances, while chemical reactions involve the transformation of one or more substances into different substances.
