Question

Fe+3 S+6 O-2 найдите формулу

Answer 1

Fe⁺³ S⁺⁶ O² найдите формулу

Fe₂(SO₄)₃ сульфат железа(lll)

Answer 2

To find the chemical formula, we need to balance the charges of the ions to create a neutral compound. The formula will have to satisfy the rule of charge balance, meaning the total positive charge (cations) must equal the total negative charge (anions) to form a neutral compound.

Fe+3 has a charge of +3. S+6 has a charge of +6. O-2 has a charge of -2.

To balance the charges, we need to find the lowest common multiple of 3, 6, and 2, which is 6. This means we need six Fe+3 ions to balance six S+6 ions and six O-2 ions.

The chemical formula is: Fe2(SO4)3

Explanation:

• Fe+3 is represented by Fe2 to balance the charge (2 * 3 = 6).
• S+6 is represented by (SO4)3 to balance the charge (3 * 6 = 18), where there are three S atoms each with a charge of +6.
• O-2 is part of the sulfate ion (SO4)-2, which has a charge of -2. Each sulfate ion contributes four oxygen atoms, and with three sulfate ions, there are 12 oxygen atoms in total.

Therefore, the formula Fe2(SO4)3 represents the compound with balanced charges.
