Final answer:
The chemical formula 4Ca(OH)2 contains three different types of elements: Calcium, Oxygen, and Hydrogen.
Step-by-step explanation:
In the chemical formula 4Ca(OH)2, there are three different types of elements present in a molecule of this compound. The elements are Calcium (Ca), Oxygen (O), and Hydrogen (H).
To analyze the formula, you can look at the components inside the brackets. Ca(OH)2 is the chemical formula for calcium hydroxide, and it consists of one calcium atom, two oxygen atoms, and two hydrogen atoms. Since the coefficient in front of Ca(OH)2 is 4, it indicates that there are four calcium hydroxide units. However, the types of elements remain the same, so the distinct elements are still just Ca, O, and H.
