Question

practice
subscripts + coefficients
· ___number at the beginning of a formula.
· represents the number of ___ for that compound.
· to find the total number of atoms, multiply each of these atoms by _, total atoms for this formula = _

Explanation:

Step1: Identify coefficient

The coefficient is the number at the beginning of a formula. For \(2H_2SO_4\), the coefficient is \(2\).

Step2: Determine what coefficient represents

The coefficient represents the number of molecules for that compound.

Step3: Find multiplier for total atoms

To find the total number of atoms, multiply each of these atoms by the coefficient.

Step4: Calculate total atoms for \(2H_2SO_4\)

• For \(H\): \(2\times2 = 4\)
• For \(S\): \(2\times1=2\)
• For \(O\): \(2\times4 = 8\)
• Total atoms \(=4 + 2+8=14\)

Answer:

1. Big (or Coefficient)
2. Molecules
3. Coefficient
4. \(14\)
