I recently got hospital homebound during the last few months of my ap chemistry class and I just can't retrach it to my self. These problems and are just a fraction of what I have on my paper. I did the first 3 before departing. I will be posting the rest soon, but I want to take it slow as I actually liked chemistry and learning it was simple to me. An explanation would be appreciated. I just couldn't walk around my school campus due to a heart condition. The balancing equation goes as products AL F + Li S --> reactants AL S + Li F

4. If 671 grams of Al F enter the reaction, how many grams of AIS are produced?

5. If 671 grams of Al F enter the reaction, what % of Al S is sulfur?

6. If 671 grams of Al F enter the reaction, how many grams of S are produced?​
