They're both are very destructed and have risk for the peiple
Answer:
8.7 mol Al
Explanation:
You have the compound Al₂Si₄O₁₀(OH)₂. Within the compound, you have atoms. You can tell how many atoms there are by looking at the subscript. You have 2 aluminum atoms, giving you 8.7 moles of aluminum.
4.35 × 2 = 8.7
Answer:
Explanation:
Atoms of each element contain a characteristic number of protons. In fact, the number of protons determines what atom we are looking at (all atoms with six protons are carbon atoms), the number of protons in an atom is called the atomic number. In contrast, the number of neutrons for a given element can vary.

<h3>What are elements?</h3>
Elements are pure substances which are composed of similar atoms.
Elements are defined as substances which cannot be split into simpler substances by an ordinary chemical process.
Elements have different physical and chemical properties and can be classified into:
- metals
- semi-metals
- non-metals
In conclusion, the physical and chemical properties of the elements vary from metals to non-metals.
