When 135 grams of titanium tetrachloride react with an excess of water, as shown in the unbalanced chemical equation below, how many grams of hydrochloric acid will be produced? TiCl4 + H2O TiO2 + HCl
First you need to balance the equation: TiCl4 +H2O = TiO2 + HCL (unbalanced) TiCl4 +2H2O = TiO2 + 4HCL (balanced)
okay than what?
Then you need to take what's given to you in the problem and convert that to mole in this case it's 135 grams of TiCl4
then you need to figure out the ratio between the mol of TiCl4 and HCL, this case it should be from the balanced equation which is 4:1 ratio
final step: you need to convert from mole to grams cuz of what the question asking ( in grams) convert from mol HCL to grams of HCL
let me write out the whole step for you hold on..
Start with 135g TiCl4 ( 1mol TiCl4/ 189.7 g TiCl4)(4 mol HCL/1 mol HCL)(36.45g HCL/1mol HCl) = 103.7 g HCL ~ 104 g HCL
if you write out what i did on paper, it would be easier for you to see what's happening...
the 189.7 came from the TiCl4 molar mass how to find molar mass: Ti = 47.90 and Cl4 = 35.45x4 =141.8 then juts add the two 47.90 + 141.8 = 189.7 g TiCl4
and the 36.45 came from molar mass of HCl
okay so the final answer is 104g of HCI right?
yes
alright thank you so much(:
