Balanced Chemical Equation:

Na2CO3 + Cacl2 ->2Nacl + CaCO3

There is 25.0 mL Na2CO3 and 25.0 mL CaCl2

.70 mol/L Na2CO3
.50 mol/L CaCl2

1. Using balanced chemical equation determine limiting reagent

What I've done so far is this: (I'm not sure if I'm correct)

Since the ratio of Na2CO3 and CaCl is a 1-1 and they both have 25.0 mL of solution all I did was look at the Mol/L values and determined that CaCl2 is the limiting reagent. I just really want to make sure of this!

Thanks for your help

Technically you should calculate number of moles of each, but your shortcut works - yes, CaCl₂ is a limiting reagent.
