How does increasing the surface area of a solid reactant affect the energy of molecular collisions?
Reactions depend on molecular collisions. If a solid reactant is a solid, grinding it into smaller particles will increase the surface area. The more surface area, the faster the molecular collisions, which in turn increases the rate of reaction.
When a substace is heated how does the molecular motion change?
When a substance is heated, the molecules within it absorb energy and increase their kinetic energy, causing them to move more rapidly. This increased molecular motion leads to increased collisions between molecules and a higher overall temperature of the substance.
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.
How does pressure create heat?
When pressure is applied to a substance, the molecules within the substance are forced closer together, causing them to collide more frequently and with greater force. This increased molecular activity generates heat as a byproduct of the increased energy and friction created by the collisions.
Which substance shows a substance that is not molecular?
A formula unit.
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 are the characteristics of a molecular substance?

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.
