For 100pts! The diagram shows the setup of an experiment. A few observations of the experiment are listed in the table below the diagram. Experimental Observations
1 Color of the solution turned blue
2 Shiny hair-like crystals deposited on the copper strip

Which of the following is the correct explanation for one of the given observations?
Observation 1 is a result of silver ions moving into the solution.
Observation 2 is a result of nitrate ions moving into the solution.
Observation 1 is a result of silver ions changing their oxidation state.
Observation 2 is a result of silver ions changing their oxidation state.

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.

oh it is true if thats what you are asking

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
