The balanced reaction that describes the reaction of chlorine gas and sodium iodide to produce elemental iodine and sodium chloride in aqueous solution is expressed Cl2+2NaI= I2 + 2NaCl. This kind of reaction is called single replacement reaction where the anion, in this case, is only replaced.
Answer:
compared to sodium, silicon has a higher ionization energy meaning it takes more energy to remove electrons.

Answer:
C; Corrosive
Explanation:
Corrosive is related to the word “Corroded”
Ever heard of when batteries get corroded? That’s when they get old so the acid leaks and damages the actual battery. Same thing. So the answer is C.
I hope this helps! :D
Pls give thx and brainliest if I’m right ;)
We have to determine if the given compound is soluble or insoluble in water.
The given compound is copper (II) hydroxide, . According to the solubility rules the hydroxides of all metal ions are insoluble except that of ammonium and the alkali metal ions. So copper(II) hydroxide will be insoluble in water. In aqueous solution, copper (II) hydroxide would exist as a sparingly soluble compound in which the undissociated compound remains in equilibrium with the ions and . The equilibrium would remain mostly towards undissociated form.
Therefore, is insoluble in water.
