a student is using colored beads to make a model of aluminum sulfate, Al2(SO4)3.
Aluminum atoms are represented by green beads, sulfur atoms by blue beads, and
oxygen atoms by yellow beads. What combination of beads should the student use for
the model?
Answers
The combination of beads should the student use for the model :2 green, 3 blue and 12 yellow
the modelFurther explanationIn the chemical formula of a compound there are numbers:
1. The number indicates the number of atoms written after the element symbol
2. The number after the parentheses represents the number multiplied by the number of atoms in parentheses.
3. The number before the chemical formula shows the number of molecules behind it, which is usually used in equations
To calculate the beads needed to make a model, we must count the number of atoms of the Al₂(SO₄)₃ molecule
In the Al₂ (SO₄) ₃ molecule there are 3 atoms : Al, S, and O
1. Number of Al atoms: 2 2. The number of atoms S = 3 x 1 = 3 3. The number of atoms O = 4 x 3 = 12So the combination of beads
2 green(for Al), 3 blue(for S) and 12 yellow(for O)
Answer:
2 blue, 3 yellow, and 12 green

stance with a mass of 85 g occupies a vol-
ume of 110 cm What is the density of
the substance? Will the substance float
in water? Explain your answer:
Answers
Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
From the question we have
[tex]density = \frac{85}{110} \\ = 0.772727272...[/tex]
We have the final answer as
0.77 g/cm³The substance will float on water since it's density is less than that of water which is
1 g/cm³.

Number of atoms : 2.245 x 10²⁴
Further explanationA mole is a number of particles(atoms, molecules, ions) in a substance
This refers to the atomic total of the 12 gr C-12 which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles
Can be formulated :
N = n x No
N = number of particles
