Answer:
The correct option is "7"
Explanation:
The compound [Ti₂(SO₄)₃] in the question is Titanium (III) sulphate. The coefficient of a compound is the number of molecules of that compound, hence "7" is the coefficient of the compound, Titanium (III) sulphate [Ti₂(SO₄)₃]. Thus, it can be expressed to mean seven molecules of Titanium (III) sulphate [7 moles of Ti₂(SO₄)₃] are in the product side of the chemical reaction .
