What else can I help you with?
Is it true or false molecular compounds that dissolve in water do not conduct electricity because no charged ions are present?
True. Molecular compounds that dissolve in water do not conduct electricity because they do not dissociate into charged ions when dissolved. Since they do not produce free ions that can carry an electric current, they are unable to conduct electricity in aqueous solutions.
How do ionic and molecular compounds differ in physical properties?
Ionic compounds have higher melting and boiling points than molecular compounds due to the strong electrostatic forces between ions. Ionic compounds are usually solid at room temperature, while molecular compounds can be solid, liquid, or gas. Ionic compounds conduct electricity when dissolved in water, while molecular compounds do not.
Are covalent molecular compounds ductile?
No, covalent molecular compounds are typically not ductile because they are made up of individual molecules held together by covalent bonds. These compounds have a molecular structure that does not allow for the same type of malleability or flexibility as metallic or ionic compounds.
What is the difference between molecular compounds and molecular element?
Molecular compounds are made up of multiple different elements bonded together, while molecular elements are made up of the same type of element bonded together. Molecular compounds have multiple types of atoms, while molecular elements have only one type of atom.
Do molecular compounds have lower melting points than ionic compounds?
Generally, yes. Molecular compounds have weaker intermolecular forces compared to the strong electrostatic forces present in ionic compounds. This results in lower melting points for molecular compounds since less energy is required to break the intermolecular forces.
True or false Low melting points and lack of eletrical conductivity are properties of molecular compounds?
True. Molecular compounds have low melting points because their intermolecular forces are weaker compared to ionic or metallic compounds. They also do not conduct electricity well because they lack free-moving charged particles.
What is the relationship between prefixes and molecular compounds?
the relationship between prefixes and molecular compounds is that, prefix are used to name molecular compounds.
How do molecular compounds bond?
When molecular compounds bond, they share electrons.
Is Compounds that are similar to water in molecular mass all exist as solids true or false?
False. Compounds that are similar to water in molecular mass can exist in various states of matter depending on their chemical properties. For example, compounds like ethanol and methanol, which have similar molecular masses to water, can exist as liquids at room temperature.
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?
Which is true of molecular compounds that dissolve in water?
Molecular compounds that dissolve in water are typically polar or can form hydrogen bonds with water molecules. When these compounds dissolve, they often separate into individual molecules rather than ions, as seen with ionic compounds. The solubility of a molecular compound in water is influenced by its molecular structure and the presence of functional groups that interact favorably with water. Examples include sugars and alcohols, which readily dissolve due to their polar characteristics.
Are molecular compounds formed from semimetals?
Yes, molecular compounds can be formed from semimetals. These compounds result from the bonding of semimetal atoms to form molecules, often through sharing electrons in covalent bonds. Examples of molecular compounds with semimetals include carbon monoxide (CO) and boron trifluoride (BF3).
Is it true or false molecular compounds that dissolve in water do not conduct electricity because no charged ions are present?
True. Molecular compounds that dissolve in water do not conduct electricity because they do not dissociate into charged ions when dissolved. Since they do not produce free ions that can carry an electric current, they are unable to conduct electricity in aqueous solutions.
How are the properties of molecular compounds different from those of ionic cmpounds?
Molecular (covalent) compounds are not dissociated in water.
How are atom arranged in molecular compounds?
Atoms are arranged in molecular compounds in groups.
Molecular compounds boil at much higher temperatures than do ionic compounds true or false?
This is false. Ionic compounds have higher boiling points than molecular compounds. For example, the boiling point of the ionic compounds copper(II) oxide, CuO, and sodium chloride, NaCl are 2,000 degrees C and 1,413 degrees C, respectively. The boiling point of the molecular compounds carbon tetrachloride, CCl4, and water, H2O are 76.72 degrees C and 100 degrees C, respectively.
Are molecular compounds made up of metals or nonmetals?
Molecular compounds are typically made up of nonmetals. Metals tend to form ionic compounds with nonmetals, whereas nonmetals tend to share electrons with other nonmetals, resulting in the formation of molecular compounds through covalent bonding.
