Answer:

True

Explanation:

Polymer is made up of monomers. Monomers are the building block of polymers.

For example, formation of polyethylene from ethylene

H₂C=CH₂ + H₂C=CH₂ → - CH₂-CH₂-CH₂-CH₂-

Ethylene molecules add to one another through addition reaction.

Water, H2O, is a molecule made of oxygen and hydrogen. The bonds that hold water molecules together are due to shared __________

adell [148]

Oxygen and hydrogen share electrons in the molecule of water to form covalent bonds.

<h3>What kinds of bonds exist?</h3>

Covalent bonds: These are formed between nonmetals and electrons by sharing electrons.
Ionic bonds: These are formed between metals, which lose electrons, and nonmetals, which gain electrons.
Metallic bonds: There are formed between metals. Electrons are delocalized in a cloud.

Water, H₂O, is a molecule made of 2 nonmetals: oxygen and hydrogen. The bonds that hold water molecules together are due to shared electrons, and known as covalent bonds.

Oxygen and hydrogen share electrons in the molecule of water to form covalent bonds.

The density of cadmium is 8.65 g/mL, what is the volume of a 33.4 g object made of pure cadmium?

Rzqust [24]

Answer:

Volume = 3.86 ml (Approx)

Explanation:

Given:

Density of cadmium = 8.65 g/ml

Mass of pure object = 33.4 g

Find:

Volume pure cadmium

Computation:

Volume = Mass / Density

Volume = 33.4 / 8.65

Volume = 3.86 ml (Approx)

Identify each of the following household substances as a strong electrolyte, weak electrolyte, or non-electrolyte: salt solution

wolverine [178]

Answer:

Electrolytes are substances that can ionize in water. They could be acids, bases or salts as long as they give ions when they dissolve in water.

Explanation:

Strong electrolytes completely ionize when dissolved in water, leaving no neutral molecules. The strong electrolytes here are: salt water, baking soda (NaHCO3) solution.
Weak electrolytes do not completely dissociate in solution, and hence have a low ionic yield. Examples of this would be vinegar and bleach (which could be sodium hypochlorite or chlorine, which are weakly dissociated).
Non-electrolytes will remain as molecules and are not ionized in water at all. In this case, sugar solution is a non-electrolytes, even though sugar dissolves in water, but it remains as a whole molecule and not ions.
