Hello gurlie (-:

Answer 3

hellow
can you help meh?

Answer 4

So, first let's calculate moles of HCl present in that solution.

Moles = Molarity X Volume.

Answer 5

Moles of HCl = ?

Answer 6

12/1*8.2?

Answer 7

99.22

Answer 8

Nopes,

Moles = 8.2 X 3.5 = 28.7

Answer 9

Second step:

1 mole of HCl reacts with 0.5 mole of Zn. So 28.7 moles of HCl will react with 28.7 X 0.5 = ? moles of Zn.

Answer 10

14.35

Answer 11

Step 3:

Convert the calculated moles of Zinc into grams by using its molar mass.

Answer 12

93.7

Answer 13

14.35 X 65.37

Answer 14

ah whoops, typo
938.7

Answer 15
