<h3>
What is a chemical equation?</h3>
- The reactants and products of a chemical reaction are represented symbolically in a chemical equation by the appropriate chemical formulas.
- A chemical equation that illustrates how Calcium oxide (quicklime) and carbon dioxide are produced during the breakdown of limestone.
CaCo3 → CaO+ CO2 (Decomposition reaction)
- The portion of the chemical equation on the reactant side is to the left of the symbol "→," and the portion on the product side is to the right of the arrow symbol.
<h3>

Answer:
- I would say the 2nd one It helps growth and repair of cells of orgasms
- But your school would probably say the 3rd one It helps remove toxins from the body to maintain homeostasis
Explanation:
2. Our cells produce a lot of waste that must be eliminated (excreted) from the body. These residues are called excreta. The residues formed from the chemical reactions that take place inside the cells can be eliminated through:
• of the respiratory system (carbon dioxide)
• skin (sweat)
urinary system (urine)
Our cells expel these substances to maintain the dynamic balance (homeostasis) of our body and promote our well-being.
Answer:
they have same atomic number as they are the same element & electrons
