When different atoms join, a new substance is formed that has properties that differ from the properties of the original atoms. Example: Hydrogen and oxygen separately are colorless, odorless gases at room temperature. When combined in a chemical reaction, they form water.

What happens when a compound undergoes a chemical reaction?

When a compound undergoes a chemical reaction, its chemical bonds are broken and reformed to result in new substances with different chemical properties. This process can involve changes in energy, formation of new bonds, and rearrangement of atoms. The reactants are transformed into products through the rearrangement of atoms.

Dr Mickster combined several nitrogen atoms together in a chemical reaction which did he create?

It is a nitrogen compound Simply because a chemical reaction happens in a compound. So, when he made a chemical reaction he made a compound.


What happens when an element combine?

In a proportional combination, a chemical reaction takes place forming a compound.


When does a compound form?

Compounds are formed in chemical reactions of either other compounds, or elements, or a combination of elements and compounds.For example burning hydrogen and oxygen is an exothermic chemical reaction that forms water, a new compound.


What happens When two molecules combine?

When two molecules combine, they can form a new compound by sharing, gaining, or losing electrons. This process is called a chemical reaction, where the atoms in the molecules rearrange to create the new compound with different properties than the original molecules.


What happens to the chemical and physical properties of a substance formed in a chemical reaction?

The chemical properties of a substance change during a chemical reaction, meaning the substance undergoes a chemical change and forms new substances with different properties. The physical properties may also change, such as color, texture, or state of matter.


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.


There are several types of evidence that suggests a chemical reaction has occurred What always happens?

One key indicator that a chemical reaction has occurred is the formation of new substances with different properties than the original reactants. This change is irreversible, meaning the reactants cannot return to their original form once the reaction has taken place. Additionally, a chemical reaction often involves the absorption or release of energy in the form of heat or light.


What happens when you break or crush ionic compounds?

When you break or crush an ionic compound, you are physically separating the individual ions that make up the compound. However, the chemical bonds between the ions remain intact, so the compound's chemical formula and properties are preserved. The compound may exhibit different physical properties, such as a change in shape or size, but its chemical composition remains the same.
