Answer 2

The chemical equation you provided consists of several reactions. Let's break it down step by step: 1. H2 + O2 = H2O This is a balanced equation for the formation of water from hydrogen gas (H2) and oxygen gas (O2). The reaction produces water (H2O). 2. Fe(OH)2 = FeO2 + H2O This equation seems to be unbalanced. The correct balanced equation for the reaction between iron(II) hydroxide (Fe(OH)2) and water (H2O) is: 2 Fe(OH)2 = FeO2 + 2 H2O 3. Mg(OH)2 = HNO2 = Mg(HO2) + H2O This equation also appears to be unbalanced. The balanced equation for the reaction between magnesium hydroxide (Mg(OH)2) and nitrous acid (HNO2) is: Mg(OH)2 + 2 HNO2 = Mg(HO2)2 + H2O It's important to note that the equation you provided, HNO2 = Mg(HO2) + H2O, is not balanced. The balanced equation for the reaction between nitrous acid (HNO2) and magnesium hydroxide (Mg(OH)2) is the one mentioned above.
