6. A student is using colored beads to make a model of aluminum sulfate, Al2(SO4)3. Aluminum atoms are represented by blue beads, sulfur atoms by yellow beads, and oxygen atoms by green beads. What combination of beads should the student use for the model? F. 6 blue, 3 yellow, and 7 green G. 2 blue, 1 yellow, and 4 green H. 2 blue, 3 yellow, and 12 green J. 6 blue, 12 yellow, and 12 green

H. 2 blue, 3 yellow, and 12 green

Explanation:

Aluminium atoms (Al) = Blue Beads

Oxygen Atoms (O) = Green Beads

Sulfur (S) = Yellow beads

From the compound Al2(SO4)3, the number of atoms present are;

Al = 2

S = 3

O = 12

This means the model would contain;

2 Blue beads

12 Green beads

3 Yellow beads

The correct option is; H. 2 blue, 3 yellow, and 12 green

colorless gas, exhibiting a blue glow when placed in an electric field

b) solid

its a type of rock
