According to coulomb’s law, which ionic compound a–d has the smallest electrostatic potential energy (i. e., closest to zero)? the size of the anion increases in the order f < cl < br < i.

3 hours because it is a decent distance.

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.
