6. A student is writing a formula for Magnesium Nitrite. He knows nitrite is a polyatomic ion with a charge of -1. Magnesium is an ion with a charge of +2. He concludes that he will need 2 nitrite ions to balance the charge
across the compound. Thus he writes the final formula as MgN, O2. Explain what he has done wrong.

See explanation

Explanation:

First of all, the student has not represented the formula of the nitrite ion correctly. The formula of the nitrite ion is represented as NO2^- whereas the student wrote N,O2.

Then, the charge on magnesium ion has been correctly designated as +2 while the charge on the nitrite ion is correctly designated as -1. Now, the ions can exchange valencies (without signs and we now write them as subscripts) to yield Mg(NO2)2.

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
