2. When zinc reacts with sulfuric acid, as shown here, what weight of hydrogen is produced from 31.8g of zinc Zn + H2 SO4 ZnSO4 + H2 What's next 1 31.8g 31.8g 1 Ask for help

3. Mr. Kirk is gonna get u

4. When zinc reacts with sulfuric acid, as shown here, what weight of hydrogen is produced from 31.8g of zinc Zn + H2 SO4 ZnSO4 + H2 Now what 31.8g x 1 Ask Mr. Kirk 1 mol Zn 65.4g Zn 65.4mol Zn 1g Zn

5. When zinc reacts with sulfuric acid, as shown here, what weight of hydrogen is produced from 31.8g of zinc Zn + H2 SO4 ZnSO4 + H2 What's next 1 mol Zn 65.4g Zn 31.8 1 x x idk 1 mol H2 1 mol Zn 6 mol Zn 1 mol H2

6. When zinc reacts with sulfuric acid, as shown here, what weight of hydrogen is produced from 31.8g of zinc Zn + H2 SO4 ZnSO4 + H2 1 mol Zn 65.4g Zn 31.8 1 1 mol H2 1 mol Zn x x x What's next 2g H2 1 mol H2 1 mol H2 2g H2 Help!

7. When zinc reacts with sulfuric acid, as shown here, what weight of hydrogen is produced from31.8g of zinc Zn + H2 SO4 ZnSO4 + H2 31.8 x 1 mol ZN x 1 65.4 g ZN 1 mol H2 x 1 mol Zn 2g H2 1 mol H2 = So what is your answer .972 g H2 9.72g H2 Pick ur nose

8. When zinc reacts with sulfuric acid, as shown here, what weight of hydrogen is produced from31.8g of zinc Zn + H2 SO4 ZnSO4 + H2 31.8 x 1 mol ZN x 1 65.4 g ZN 2g H2 1 mol H2 = 1 mol H2 x 1 mol Zn ..972 g H2 YEAH!!!!!!!!!! U DID IT MR. KIRK IS VERY PROUD Click here to receive a prize
