Question

Question 4 (1 point) Consider the "mixed melting point" technique.(Select all that apply.) If the melting point of the mixture is lower than the melting point of the separate compounds, then the two compounds are different. If the melting point of the mixture is the same as the melting point of the separate compounds, then the two compounds are different. If the melting point of the mixture is the same as the melting point of the separate compounds, then the two compounds are the same. If the melting point of the mixture is the lower than the melting point of the separate compounds, then the two compounds are the same. Save

Explanation / Answer

Ans : If the melting point of the mixture is lower than the melting point of the seperate compounds , then the two compound are different.

When two compounds are mixed to form a mixture , the physical properties of the mixture tend to change.Usually a decrease in melting point is observed due to the disruption of crystal lattice energies.
