Question

Write a balanced equation for each of the following:

1) Fe₂O₃ + H₂SO₄ −−> Fe₂(SO₄)₃ + H₂O

2) C₂H₆ + O₂ −−> CO₂ + H₂O

3) Mg_(s) + O_2(g) −−> MgO_(s)

Answer 1

1.$Fe_2O_3 (s)+3 H_2SO_4 (aq) → Fe_2(SO_4)-3 (s) + 3 H_2O (l)$

2.$C _2 ​ H _6 ​ + \frac {7}{2} ​ O _2 ​ →2CO _2 ​ +3H 2 ​ O$

3.$2Mg(s) + O₂(g) → 2MgO$
