Predict the molar ratio in which the following two substances would react ?
`Ba_(3)(PO_(4))_(2) " and " AlCl_(3)`.

Explanation

To predict the molar ratio in which the substances \( \text{Ba}_3(\text{PO}_4)_2 \) and \( \text{AlCl}_3 \) would react, we can follow these steps:

### Step 1: Determine the n-factor of \( \text{Ba}_3(\text{PO}_4)_2 \)

- The formula \( \text{Ba}_3(\text{PO}_4)_2 \) contains 3 barium ions (Ba²⁺) and 2 phosphate ions (PO₄³⁻).
- Each barium ion has a charge of +2, so the total charge contributed by barium is:
\[
3 \times (+2) = +6
