PLEASE HELP SOON Assume a reaction takes place in a basic solution to form the given products:
MnO4-(aq) + Cl-(aq) --> MnO2(s) + Cl2(g) (unbalanced)

Balance the given half-reactions for atoms and charge.
MnO4- + H2O --> MnO2 + OH-
Cl- --> Cl2

the answer is: they rebelled against saddam hussein’s rule.

kurds opposed saddam rule and wanted independence. kurds in the north and shiites in the south revolt against hussein.

for example, the halabja attack in 1988 conducted against the kurdish people by the iraqi regime under saddam hussein, where between 4000 people are killed and around 9000 are injured.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

i believe the answer is true.
