How do you differentiate simple molecular compounds and giant molecular compounds?
simple molecular compounds have weak forces of atraction.
Are molecular compounds formed from semimetals?
Molecular compounds certainly can be formed from semimetals, but not all the compounds of semimetals are molecular.
What holds covalently bonded atoms together and what are the properties of molecular compounds?
In a covalent bond the electrons are shared between atoms.
Why is it that only molecular compounds can have a molecular formula?
Because there are no compounds that aren't molecules/molecular. The question as posed is nonsense. Rephrase?
Are molecular compounds reactive?
yes
What is the electrical conductivity of ionic compounds?
better than the electrical conductivity of molecular compounds
Why is the conductivity value of deionized water subtracted from the conductivity values of molecular compounds?
because
What is a property of molecular compounds?
Molecular compounds are composed of neutral molecules, their electrical conductivity is generally quite poor, whether in the solid or liquid state.
How are the properties of molecular compounds different from those of ionic cmpounds?
Molecular (covalent) compounds are not dissociated in water.
The properties of both ionic and molecular compounds are related to the?
strengths of attraction between the particles in the compounds
What are the properties of molecular compound?
Molecular compounds generally do not conduct electricity and have low melting points.
What are properties of a molecular compound?
Molecular compounds are built upon molecules that consist of more than one element such as water (H2O) or carbon dioxide (CO2). The common properties are low melting and boiling points, poor electrical and thermal conductivity, soft or brittle solid forms and low enthalpies of fusion and vaporization.
What accounts for the observed differences in the properties of ionic and molecular compounds?
t Answer Well firstly, ionic compounds form from metals bonding with non metals. Molecular/covalent form from non metals bonding with non metals. A strong electrostatic force between ionic compounds results in them having high melting points. A weaker electrostatic force between molecular compounds results in them having lower melting points and thus weaker bonds. Ionic compounds are made up of ions, so will conduct electricity. Covalent compounds only share electrons and so are not ions, and will not conduct electricity.
What are some properties of molecular compounds?
Simple molecular structures like H2O and CO2 have the following properties: 1) Physical state: usually liquids and gases at room temperature due to weak intermolecular forces 2) Melting and boiling points: low (below 2000 C) melting and boiling points due to weak intermolecular forces 3) Electrical conductivity: cannot conduct electricity because there are no free electrons 4) Solubility: insoluble in water, but soluble in organic substances such as petrol Macromolecular structures such as diamond and SiO2 have the following properties: 1) Physical state: hard solids at room temperature due to the many strong covalent bonds holding the atoms together 2) Melting and boiling points: high melting and boiling points due to the many strong covalent bonds that must be broken before the substance can change state 3) Electrical conductivity: cannot conduct electricity because there are no free electrons 4) Solubility: insoluble
What is true about molecular compounds?
Two or more elements are chemically bonded.
How are the properties of molecular compounds poor conducters of electricity?
Because have lower melting points and boiling points
Are molecular compounds formed from semimetals?
Molecular compounds certainly can be formed from semimetals, but not all the compounds of semimetals are molecular.
