The correct definition of density is the degree of compactness of a substance.
Because of its chemical structure.
Answer:
Color change, precipitation, bubbling
Explanation:
Chemical change changes the chemical composition and undergoes a process in which it results as a new substance.
Answer:
Macromolecule: polymer
Repeating units: monomer
Simple molecule: monomer
Covalent bonds: both
Explanation:
A macromolecule is a very large molecule commonly created by the polymerization of smaller subunits called monomers. They are typically composed of thousands of atoms or more.
A monomer is a molecule that can be reacted together with other monomer molecules to form a larger polymer chain.
Polymers include bounds between nonmetal atoms, therefore, they are joint by covalent bonds
The ratio of the diffusion rate of Cl2 and O2 is 1.5
calculation
rate of diffusion Cl2/ rate of diffusion O2 =√ molar mass of Cl2/ molar mass of O2
molar mass of Cl2 = 35.5 x2 = 71 g/mol
molar mass O2 = 16 x2 =32g/mol
that is rate of diffusion Cl2/ rate of diffusion of O2 =√ 71/ 32= 1.5
