Answer:
<h2>
32°F
/0°C
</h2>
Explanation:
At what temperature does the melting point occur?
32°F
/0°C
(32°F − 32) × 5/9 = 0°C
At temperatures above 32°F (0°C), pure water ice melts and changes state from a solid to a liquid (water); 32°F (0°C) is the melting point. For most substances, the melting and freezing points are about the same temperature.
Is Melting Point affected by temperature?
Melting point, the temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change.
Answer:
1.81 x

Explanation:
Use Avogadro's number:
3 moles H2 x 6.022 x 
molecules= 1.81 x molecules H2

Polymers are the molecular structure in which the larger number of small units are bond together.
Explanation:
The polymer are composed of hydrocarbon the components of carbon and hydrogen. The polymers are resistant to chemiclas, they act as both thermal and electrical insulators, they can be processed in various ways usually made up of petroleum. polymers are used to make items that have no alternatives from other material.
They have covalent bonds that holds the atoms in the polymer molecules together and secondary bonds that holds group of polymer chains together to form the polymeric material.
Diamond and graphite are polymers.
Carbon dioxide is a molecule with molecular formula CO2 and it is made up of two oxygen atoms and covalently bonded with one carbon atom.
