When water is heated, bubbles form in the water. Is this evidence of a chemical reaction? Why? Question 2 options: No, boiling water is a physical change. Yes, the formation of a gas is evidence of a chemical reaction. No, the formation of gas bubbles is a secondary chemical reaction which is ignored. Yes, the formation of a gas is proof a new compound has been made. none of the above

No, boiling water is a physical change.

Explanation:

Physical change is a change in which there is no rearrangement of atoms and thus no new substance is formed. There is only change in physical state of the substance.

Boiling water  is a physical change as liquid changes to gaseous state and no new substance is being formed.

Chemical change is a change in which there is rearrangement of atoms and thus new substance is formed. There may or may not be a change in physical state.

chemists can use the electron cloud model to assign electrons to different atomic orbitals. atomic orbitals also explain the patterns in the periodic table

explanation:

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
