The term "3 fecl2" in a balanced equation says a) that there are three iron(ii) ions and two chloride ions bonded together. b) that there are three iron(ii) ions and 6 chloride ions bonded together. c) that there are three formula units, each consisting of two chloride ions bonded to an iron(ii) ion. d) that there are three particles, each consisting of three iron atoms and 6 chlorine atoms.

Answer : The correct option is C.

Explanation :

In , 3 ions and 6 ions are present. is formed when two ions bonded to an ions.

Thus, the term in a balanced chemical equation says that there are three formula units, each consisting of two chloride ions bonded to an iron(II) ion.

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.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
