Stoichiometry can be used to calculate the energy absorbed when a mass melts by considering the enthalpy of fusion, which is the amount of energy required to change a substance from solid to liquid at its melting point. By using the molar mass of the substance and the enthalpy of fusion, you can calculate the amount of energy needed to melt a specific mass of the substance.

How is stoichiometery used to calculate energy absorbed when a mass of a solid melts?
Stoichiometry can be used to calculate the energy absorbed when a mass of a solid melts by considering the heat energy required to overcome the intermolecular forces holding the solid together. By using the heat capacity of the solid, the mass of the solid, and the enthalpy of fusion for the substance, stoichiometry can help determine the amount of energy needed for the solid to melt.
How is stoichiometry used to calculate energy released when a mass of solid melts?
Stoichiometry can be used to calculate the energy released during the melting of a solid by determining the amount of heat required to convert the solid to a liquid. This conversion involves breaking intermolecular forces but does not change the chemical composition. The energy required can be calculated using the heat of fusion, which represents the amount of energy needed to melt one mole of a substance at its melting point.
Why is energy absorbed when ice melts?
Energy is absorbed when ice melts because the process of melting requires breaking the intermolecular forces holding the water molecules in a solid state. This breaking of bonds requires energy input, known as the heat of fusion. This energy is used to overcome the attractive forces between the water molecules, allowing them to move more freely and transition from a solid to a liquid state.
What does positive enthalpy mean?
Positive enthalpy means that energy is absorbed from the surroundings during a process. This usually indicates an endothermic reaction where heat is taken in. For example, when ice melts into water, it absorbs heat from its surroundings, resulting in a positive enthalpy change.
What has a change of state reaction that energy is endothermic?
One example of a change of state reaction that absorbs energy is the melting of ice. When ice melts and changes from a solid to a liquid state, it absorbs heat from its surroundings to break the intermolecular forces holding the water molecules together in a rigid structure. This absorption of energy is why melting ice feels cool to the touch.

When a substance changes from solid to a liquid?
It melts. Energy is absorbed.
How much heat energy is absorbed when 171 g of ice melts?
To calculate the heat energy absorbed when 171 g of ice melts, we use the formula ( q = m \times L_f ), where ( L_f ) is the latent heat of fusion for ice, approximately 334 J/g. Therefore, the heat energy absorbed is ( q = 171 , \text{g} \times 334 , \text{J/g} = 57,054 , \text{J} ) or 57.1 kJ.
When ice melts to form water energy is what?
When ice melts to form water, energy is absorbed in the form of heat. This process requires energy to break the bonds holding the ice molecules together, causing them to transition from a solid to a liquid state.
Is energy absorbed or released when a solid melts a liquid vaporizes a gas condenses and a liquid melts?
Melting and boiling (vaporization) absorb energy, freezing and condensing release energy.
The change in which ice absorbs energy and melts is a?
Endothermic reactions are those in which energy is absorbed during the reaction. Exothermic reactions are those in which heat is evolved during the reactions.When ice melts its absorbs energy in the form of heat so why it melts,
What is known as the energy absorbed by one gram of ice as it melts?
The energy absorbed by one gram of ice as it melts is known as the heat of fusion. This process requires a specific amount of energy to overcome the intermolecular forces holding the ice molecules together and transition from a solid to a liquid state.
How is stoichiometry used to calculate energy absorbed when a mass of a solid melts?

To calculate the amount of heat absorbed as a substance melts what information is not needed?
To calculate the amount of heat absorbed as a substance melts, you do not need information about the substance's boiling point or its specific heat capacity in the liquid state. The key parameters needed are the substance's heat of fusion (melting) and the mass of the substance melting.
The energy absorbed by one gram of ice as it melts as known as the .for water?
The energy absorbed by one gram of ice as it melts is known as the heat of fusion for water. This energy is required to break the intermolecular forces holding the ice molecules together and convert the solid ice into liquid water at its melting point.
