Using Hess's Law rearrange the fiven reactions to determine the heat of reaction for Fe2O3(s) + 3 CO(g) --> 2 Fe(s) + 3 CO2(g)

Explain waht needs to ve done to each reaction to determine the final reaction desired

reaction 1: 2 Fe(s) + 3/2 O2(g) --> Fe2O3(s) ^H = -824.2 KJ/mol

reaction 2: CO(g) + 1/2 O2(g) --> 2 CO2(g) ^H = -282.7 KJ

First reaction: ^ H becomes KJ/mol

second reaction ^H becomes KJ/mol

heat of reaction is KJ/mol

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."

can you list the answers so i can answer

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: )
