Draw the lewis structure for each atom and show how the bond between them is formed. remember to include the charges if it is an ionic bond. Make sure to write the formula for the compound formed. Hydrogen + Sulfur
Potassium +Nitrogen
Magnesium + Phosphorus
Silicon + Chlorine
Lithium + Iodine
Bromine + Bromine

you know what to do come on

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
