Hcl (g) + o2 cl2 (g) + h2o (g)

assuming that all the gases in this reaction are at stp, what number of molecules of hydrogen chloride gas are needed to completely react with oxygen to yield 50.00 ml of chlorine gas?

PV = nRT

Pressure times volume = number of moles times ideal gas constant times temperature

50mL = .05L

1 atm (.05) = n (.0821) (273)

.05 = n (22.4133)

.022 = n (number of moles)

6.022E23 molecules = 1 mole

.022 x 6.022E23 = 1.325E23 molecules

Answer    "a salt" would be the best answerexplanationsalts can be defined as ionic compounds that are neither acids nor bases. nacl is an example of a salt, and its ionic.an enzyme is an organic compound which is covalently bonded, not ionically bonded.acids are generally held together by covalent bondsan element does not need any bonds to exist

Answer-ide.
