Equation: CO2 (g) + HOH (l) <--> H2CO2 (g) When equilibrium has been established explain in terms of reaction rates why the concentration of reactants and products remains the same.

I don't really know the answer sorry I'm not smart enough

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

a corroding iron, if that's one of your choices
