Adults have stem cells because they are needed to repair certain tissues in the body such as in the muscles, bone marrow, skin, teeth, heart, and liver, to name a few. Thus, they can develop into many different cell types and function to replace older and damaged tissues.
(anode +) Cu⁰(s) - 2e⁻ → Cu²⁺(aq)
When a electron moves from higher shell to lower shell ,it releases energy because if it goes to lower shell without releasing energy then it will unable to do that so.as lower electron shells have low energy electrons
Answer:
coefficient 3 is needed t with water molecule to balance the equation.
Explanation:
Chemical equation:
Fe₂O₃ + H₂SO₄ → Fe₂(SO₄)₃ + H₂O
Balanced chemical equation:
Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O
The equation is balanced. There are two iron three sulfate six hydrogen and three oxygen atoms are present on both side of equation.
The given equation completely follow the law of conservation of mass.
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Coefficient with reactant and product:
Fe₂O₃ 1
H₂SO₄ 3
Fe₂(SO₄)₃ 1
H₂O 3
So coefficient 3 is needed t with water molecule to balance the equation.
