Is formation of water from its element physical change?
No, the formation of water from its elements (hydrogen and oxygen) is a chemical change because new substances with different properties are formed. In this case, a chemical reaction occurs between hydrogen and oxygen molecules to produce water molecules.
What occurs when two or more molecules interact and the molecules change into a new substance?
When two or more molecules interact and change into a new substance, a chemical reaction occurs. During this process, the bonds between atoms in the reactant molecules are broken, and new bonds are formed to create different products. This transformation typically involves the rearrangement of atoms and can result in the release or absorption of energy. The new substance formed usually has distinct physical and chemical properties compared to the original molecules.
When elements or molecules combine to form a new compound what reaction it occurs?
When elements or molecules combine to form a new compound, a chemical reaction occurs. This process involves the rearrangement of atoms to create new bonds and result in a different composition than the original substances.
What is formed when a chemical change occurs?
When a chemical change occurs, new substances are formed with different chemical properties than the original substances. This process involves the breaking and forming of chemical bonds to create new molecules.
When chemical bonding occurs?
Chemical bounding takes place when one different type of atom combines or reacts wth an other different type of atom to create a chemical reaction. for example iron oxide reacts with carbon to get iron + carbon dioxide
Are new molecules formed when a chemical change occurs?
ye s there are
What type of change occurs in a chemical reaction?
In a chemical reaction, a chemical change occurs where the chemical composition of the substances involved is altered, leading to the formation of new substances with different properties. This change involves the breaking and forming of chemical bonds.
What is it called when atoms are rearranged to form a new substance?
A chemical change occurs when atoms are rearranged to form new molecules.
What type of chemical bond occurs between atoms in molecules such as h2 ch4 nh3 h2 cch2 n2 cl2 and many large biological molecules?
covalent bonds --- sharing electrons
What is a relatively weak bond between polar molecules?
A hydrogen bond is a relatively weak bond formed between polar molecules. It occurs between a hydrogen atom bonded to an electronegative atom (such as nitrogen, oxygen, or fluorine) and another electronegative atom in a different molecule.
What type of reaction occurs when atom combine to form molecules or when molecules break down into atoms?
Chemical reactions occur when atoms combine to form molecules (synthesis reaction) or when molecules break down into atoms (decomposition reaction). These reactions involve the rearrangement of atoms to form new substances with different properties.
What reaction occurs when the bonds of the reacting compounds are broken and new combinations are formed?
A chemical reaction occurs when the bonds of the reacting compounds are broken and new combinations are formed. This process involves the rearrangement of atoms to form new molecules with different chemical properties.
