Which of these 2 elements will react similarly? *
Be, CI
Na, K
O Na, Mg
Na, CI

Na, K

Explanation:

From the given choices, the two elements that will react similarly are Na and K.

This is because, Na and K are in the same group on the periodic table.

Na and K are both called Alkali metals and they have just one electron in their outermost shell.

The number of electrons in the outermost of an atom determines their chemical properties.

Since Na and K are in the same group, they chemically combine with other atoms in similar fashion.

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.

c is the answer because when something is left after something evaporates that shows the chemical change.
