Need help with these chemistry quesions about mole ratios. There's an image linked to this. Please help

Answer 1

1) moles Al : moles of HCl

2 : 6

simplifying the ratio;

1 : 3

2)
`HCl : AlCl_(3)`

6 : 2

3 : 1

3)
`Al : AlCl_(3)`

2 : 2

1 : 1

4)
`HCl : H_(2)`

6 : 3

2 : 1

5)
`HCl : H_(2)`

2 : 1

6 : x

x = 6/2

x = 3 moles

6)
`HCl : H_(2)`

2 : 1

12 : x

x = 12/2

x = 6 moles

7)
`HCl : H_(2)`

2 : 1

3 : x

x = 3/2 moles
