calcium: 240/40.1 = 5.985 = 6 mol chlorine: 426/(35.5x2) = 6 mol mole ratio of Ca(s) and Cl2(g) = 6:6 = 1:1 so the empirical formula of calcium chloride reactant is CaCl2
OMG, that makes soooo much more sense now. I wasn't sure what they were asking me to do thank you!!!!
Ohhhhhhh I've just read that back and you state the reactant is CaCl2 and the products are Ca and Cl2, the Math is correct but it's for the decomposition of CaCl2 so equation is actually the reverse. I always misread when I did my A-level Chem questions and I still do to this day

6Cacl2 --> 6Ca + 6Cl2
I got that, so I changed it round anyway . Thanks again!
