What is the equilibrium expression for 2Cl2 + 2H2O ⇌ 4HCl + O2? a.)[HCl] 4 [O2]/ [Cl2] 2 b.)[H2O] [Cl2] 2 /[HCl] 4 [O2] c.)[HCl] 4 [O2]/[H2O] [Cl2] 2 d.)[HCl] 4 [O2]/[H2O] 2 [Cl2] 2 I REALLY NEED HELP ON THIS ONE! 10 points!

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

im pretty sure its b
