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

131.8g

Ask for help

31.8g 1

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

31.8g

1x

Ask Mr. Kirk 1 mol Zn65.4g Zn

65.4mol Zn 1g Zn

GREAT!!!!!!! Now what

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

31.8 1

x 1 mol Zn65.4g Zn

EXCELENT!!!!!!!! What's next

idk 1 mol H21 mol Zn

x

6 mol Zn 1 mol H2

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

31.8 1

1 mol Zn65.4g Znx x 1 mol H2

1 mol Zn x

DOIN GREAT !!!!!!!! What's next

2g H21 mol H2 1 mol H2

2g H2 Help!

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

31.8 x 1 mol ZN x 1 65.4 g ZN

So what is your answer

.972 g H2

Pick ur nose

9.72g H2

1 mol H2 x1 mol Zn

2g H2 1 mol H2 =

31.8 x 1 mol ZN x 1 65.4 g ZN

1 mol H2 x1 mol Zn

2g H2 1 mol H2 =

YEAH!!!!!!!!!! U DID IT MR. KIRK IS VERY PROUD

..972 g H2
