Q1- Calculate the mass of ammonia NH3 if 9 moles of NH3 is used in a chemical reaction. Determine its molar mass and use it to convert moles to
mass in grams.​

give me abc and i will get it for u.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
