Question

for the following formula, match the definition to the numerical value: 4al₂s₃

Explanation:

Step1: Identify Coefficient

The coefficient is the number in front of the formula. In \(4Al_2S_3\), the coefficient is \(4\).

Step2: Identify Subscript for \(Al\)

In \(Al_2S_3\), the subscript for \(Al\) is \(2\). To find the total number of \(Al\) atoms, multiply the coefficient by the subscript: \(4\times2 = 8\).

Step3: Identify Subscript for \(S\)

In \(Al_2S_3\), the subscript for \(S\) is \(3\). To find the total number of \(S\) atoms, multiply the coefficient by the subscript: \(4\times3=12\).

Step4: Match Definitions

• Element Symbol: \(Al\)
• Coefficient: \(4\)
• Subscript (\(Al\)): \(2\)
• Subscript (\(S\)): \(3\)
• Total # of \(Al\) atoms: \(8\)
• Total # of \(S\) atoms: \(12\)

Answer:

Element Symbol	Coefficient	Subscript	Total # of Al atoms	Total # of S atoms
