What is the sum of the coefficients of the following balanced chemical equation? ki + pb(no3)2 → kno3 + pbi2 a) 6 b) 10 c) 18 d) 20

A) 6.

Explanation:

2KI + Pb(NO₃)₂ → 2KNO₃ + PbI₂,

It is clear that 2.0 moles of KI react with 1.0 mole of Pb(NO₃)₂ to produce 2.0 moles of KNO₃ and 1.0 mole of PbI₂.

So, the sum of the coefficients is 6.

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

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: )
