Converting Chemical Reactions to Equations

To convert chemical reactions into equations, we need to balance the number of atoms on both sides of the reaction. Let's convert the given reactions into equations and balance them:

1. H2 + O2 -> H2O - This is the equation for the formation of water from hydrogen and oxygen. - To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. - The balanced equation is: 2H2 + O2 -> 2H2O.

2. O2 -> P2O5 - This equation represents the formation of phosphorus pentoxide from oxygen. - To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. - The balanced equation is: 4O2 -> 2P2O5.

3. H2 + P -> PH3 - This equation represents the formation of phosphine from hydrogen and phosphorus. - To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. - The balanced equation is: 4H2 + P -> 4PH3.

4. H2O2 -> H2O + O2 - This equation represents the decomposition of hydrogen peroxide into water and oxygen. - To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. - The balanced equation is: 2H2O2 -> 2H2O + O2.

5. O2 + Mg -> MgO - This equation represents the reaction between oxygen and magnesium to form magnesium oxide. - To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. - The balanced equation is: 2O2 + 2Mg -> 2MgO.
