30g of TiCl4 is mixed with 18g of water to from TiO2 and HCl. Write the chemical reaction and balance it.How much TiO2 is produced.
my answer:
TiCl4+2H2O= TiO2+4HCl

TiCl4+2H2O=TiO2+4HCl
The equation is ok.
This is a limiting reagent (LR) problem and you know that because amounts are given for both reactants.
mols TiCl4 = grams/molar mass = ?
mols H2O = grams/molar mass = ?
Using the coefficients in the balanced equation, convert mols TiCl4 to mols product. Do the same for mols H2O to mols product. It is likely these two values will not agree which means one is not right;the correct value in LR problems is ALWAYS the smaller value and the reagent producing that value is the LR.
Now convert that smaller value to grams product by grams = mols x molar mass = ?
