Total density of filled ball with carbon dioxide gas: 
The relationship between mass and volume can be easily determined using density; for example, the mass of a body is equal to its volume multiplied by the density (M = Vd), whereas the volume is equal to the mass divided by the density (V = M/d). The ball filled with carbon dioxide will not float in the air because total density of filled ball is greater than the density of an air. Density of the evacuated ball D = 0.214 g/L
Density of carbon dioxide gas = 
Mass of the carbon dioxide gas :

Answer:
Glucose and glycogen.
Explanation:
Hello,
Monomers are the functional molecules forming the polymers when an random amount of units (monomers) are linked form an assembly (polymer).
This could be exposed by considering the glucose as the monomer forming the glycogen which is a polymer that serves as a form of energy storage in animals, fungi, and bacteria; it is constituted by about 30,000 units of both lineal and branched glucose which provide many features that the glucose doesn't have by itself.
Best regards.
Divide the mass of the proton by the mass of the electron.
3) Answer is: because elements have different emmision spectrum.
Emission spectrum of a chemical element is the spectrum of frequencies emitted due to an atom making a transition from a high energy state to a lower energy state. Each element's emission spectrum is unique.
4) Answer is: lithium chloride and sodium chloride do not have similar colors.
Lithium ion has red and sodium ion has yellow emission spectrum.
5) Answer is: because metals have valence electrons in different energy shells.
Each transition has a specific energy difference.
6) Answer is: salts of alkaline and earth alkaline metals.
For example barium chloride gives green light.
A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture.
A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture.
