Suppose you use 0.0150 liter of a 2.50 m solution of silver nitrate. assuming the reaction goes completion how much silver sulfide is produced

M= Moles/ L

2.50=x/0.0150

x=0.0375 moles

moles x mm= grams

0.0375 x 247.8= 9.2925 grams

the answer is                                                                                                            

C. 9.30 g

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
