Characteristics of a molecular substance?
low melting point
What small particle of substance retains the characteristics of the substance?
If it is an element, then the smallest particle that retains the characteristics of the element is an atom. If it is a diatomic element, then the smallest particle that retains the characteristics of the element is a molecule. If it is a molecular compound, then the smallest particle that retains the characteristics of the compound is a molecule. If it is an ionic compound, the smallest particle that retains characteristics of the compound is a formula unit.
What is a gram of a molecular substance?
A gram of a molecular substance is the quantity that will have a mass of 1 gram.
What substance has a molecular weight of 765.82?
The substance with a molecular weight of 765.82 is the antibiotic called Azithromycin.
Which substance shows a substance that is not molecular?
A formula unit.
What can describes a chemicalproprety of a substance?
A chemical property of a substance describes how it reacts with other substances to form new compounds. This includes characteristics such as flammability, reactivity, and ability to corrode or oxidize. Chemical properties are determined by the substance's molecular structure and composition.
A substance is permanently altered by?
A substance is permanently altered by undergoing a chemical reaction that changes its molecular structure, composition, or properties. This alteration is often irreversible and results in the formation of new substances with different characteristics than the original substance.
What is the freezing point of a substance with a molecular weight of n2?
The freezing point of a substance with a molecular weight of N2 is -210.01 degrees Celsius.
What is a molecule a group of?
A Molecular Substance or Compound.
How is a molecular substance similar and different from molecular elements?
"Molecular element" is a much narrower category than "molecular substance". The kinetic units* of a molecular element contain at least two atoms, but all the atoms in the kinetic unit must be atoms of the same element. A molecular substance may contain any number of atoms of any number of elements. Therefore, every molecular element is a molecular substance, but the reverse is not true. The only additional requirements for a molecular substance are that all its kinetic units must have the same chemical composition and must contain at least two atoms but must not have any net electrical charge. ____________________________________________ *A kinetic unit is the smallest portion of a substance that moves further apart on average from other kinetic units when the substance expands while maintaining nearly constant interatomic distances within the kinetic unit itself.
Can one substance have same empirical and molecular formula?
Yes, it is possible for a substance to have the same empirical and molecular formula. This can occur when the substance is composed of only one type of element, such as oxygen gas (O2), where both the empirical and molecular formula are O2.
What is the significance of the molecular mass (symbol) in determining the properties of a substance?
The molecular mass (symbol) of a substance is significant in determining its properties because it affects how the substance interacts with other molecules. Substances with higher molecular masses tend to have different physical and chemical properties compared to substances with lower molecular masses. This is because the molecular mass influences factors such as boiling point, melting point, and solubility, which are important in understanding the behavior of a substance.
