From Solid to Liquid: The Melting Point Experiment In this experiment, my students work to identify an unknown organic compound by comparing it to a set of known pure compounds (like benzoic acid or dextrose). They use Vernier Go Direct® Melt Stations to observe how each compound melts at...
Melting point determination is the basic means to identify the nature of the substance, and is also one of the important methods to determine the purity. In this article, we propose an artificial neural network method to predict organic compounds, melting point. Taking the molecular weight, ...
Answer to: When you mix two compounds, the melting point of the compound is lowered, but the boiling point is elevated. Explain why. By signing up,...
The preparation and properties of ZnSiAs2, ZnGeP2 and CdGeP2 semiconducting compounds*1 Preparation of the phosphides was carried out with an internal heating high-pressure resistance furnace. The following physical and electronic properties of these compounds were measured: the melting point, lattice...
In order to achieve this, a group of organic compounds were selected (alkanes, alcohols etc.) to plot their melting point and find a good regression. A critical study of the properties that affect the melting point was conducted. After trying a couple of regressions, a statistical analysis ...
How to determine which compound has the highest/lowest melting point? You have two unknown compounds that are composed of non-metals. Compound X has a melting point of 289 K and compound Y has a melting point of 864 K. What type of solid is compound X? And what type of solid is comp...
Melting Point In subject area: Physics and Astronomy Melting point refers to the temperature at which a solid substance changes into a liquid state. In the context of organic compounds, the melting point is used as an important criterion to evaluate structural changes. It can vary significantly ...
Which metal has the highest melting point? View Solution Which of the following compounds has the lowest melting point ? View Solution Which of the following compounds has the highest boiling point ? View Solution Explain the following: lonic compounds have high melting point and boiling point whil...
The boiling point of a compound can be determined from additive constitutive properties, but the melting point can be estimated only with the aid of nonadditive constitutive parameters. The melting point of some non-hydrogen-bonding, rigid compounds can be estimated by the equation MP = 0.772 * ...
Sample preparation process using METTLER TOLEDO melting point tools: Step 1: First, the sample needs to be dried in a desiccator. Then a small portion of sample is finely ground in a mortar. Step 2: Several capillaries are prepared simultaneously for measurement with a METTL...
