Answer:
The cube A is magnesium, the cube B is aluminum and the cube C is silver.
Explanation:
Density is defined by the expression 
where m is the mass and V is the volume, therefore:
- Density of the cube A:
- Density of the cube B:
- Density of the cube C:
Solving for mass:
And all the three cubes have the same mass, so:
Therefore:
(Eq.1)
(Eq.2)
Solving for 
in Eq.1:
Replacing values for the volume:
As we know the density of the aluminum is 
, so replacing this value for 
:
that is the density of the magnesium.
Solving for 
in Eq.2:
That is the density of the silver.
Therefore the cube A is magnesium, the cube B is aluminum and the cube C is silver.
Answer:
Explorations include static electricity, magnets, electromagnets and permanent magnets. Examples of cause and effect relationships could include how the distance between objects affects strength of the force and how the orientation of magnets affects the direction of the magnetic force.

Notice that you have a 2
:
3 mole ratio between potassium chlorate and oxygen gas, which means that, regardless of how many moles of the former react, you'll always produce 2/3 times more moles of the latter.
15 mol of O2 * ((2mol of KCLO3)/(3mol of O2))= 15*2/3=10 Mol
It would be considered a Homogeneous Mixture. A mixture with two or more components mixed evenly is a Homogeneous mixture.
You can search that up online it’s not that hard but good luck !!
