1. Given the following balanced chemical equation: 2AIN +
3F2 -->
2AlF3
+
N2
a. How many grams of AIN are needed to react with 1.23 moles of F2?
b. How many moles of N2 are made from 0.346 moles of F2?
c. How many moles of AlF3 are produced from 11.8 g of AIN?
d. How many grams of AlF3 are formed from 8.84 g of AIN?

the answer is a. co2, this would be colder than the : )

explanation:

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.

(b) which contains higher levels of vitamin b, oranges or spinach?

explanation:

you can eliminate a, c, and d because they are questions based on opinions.
