How many formula units of agno3 are there in 3.25 mol of agno3?

1.96 ×10²⁴ formula units AgNO3

Explanation:

3.25mol AgNO3 × (6.02 × 10²³ formula units) = 1.96 ×10²⁴ formula units AgNO3

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

i believe it is-

d.) gravity pulled particles of dust and gas together to form planets.
