Note that the density of pure aluminum is 2.7 g/cm³ (from tables).
Given:
m = 39.0 g, the mass of the metal
V = 10.0 cm³, the density of the metal
By definition, the density of the metal is
density = mass/volume
= (39.0 g)/(10.0 cm³)
= 3.9 g/cm³
Answer:
The calculated density is not equal to 2.7 g/cm³, therefore the metal sphere is not made of pure aluminum.
Answer: 
Explanation:
Solubility product is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as
The equation for the ionization of the 
is given as:
When the solubility of is S moles/liter, then the solubility of 
will be S moles/liter and solubility of 
will be 2S moles/liter.
By stoichiometry of the reaction:
1 mole of gives 1 mole of 
and 2 moles of

Answer:
The starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products.
This segment is called a gene
