Melting and Boiling Point: Every substance can change its physical state according to the temperature. The rise and fall of temperature can convert a substance can change a solid into liquid and gas and vice versa. Answer and Explanation:1 ...
Melting pointThe physical properties like melting point and boiling points depends on the intermolecular forces and molar mass of compounds. We can some time differentiate a mixture of compounds based on their differences in these properties.
The principle of solubility, "like dissolves like," emphasizes the importance of polarity in determining whether substances will mix. Polar molecules, such as water and ethanol, dissolve in each other due to their similar net dipoles. Understanding the polarity of various organic compounds,...
When we observe the reactivity of multiple substances, this can be indicative of a wide variety of interactions and properties. Common reactions typically alter the chemical bonds of reactants creating new chemical reaction products. This can also involve a change in states of matter. A common ch...
However, they can help us make much, much better ice cream. And that's the most important point here. We're not using them to save money. We're not using them to cut corners. When we use them, we use them to deliver better texture, better body, a more creamy, luxurious finish. ...
Also by using the molecular weight of glucose (342.3) it can be determined that the average degree of polymerization of the corn syrup solids is 2.669. These numbers were calculated based on boiling point data. A freezing point experiment was not conducted. This data makes sense, for corn syr...
Now, it's time for you to see Raoult's law in action. Know as you approach these problems that you can always look up values for Pvaporfor particular substances. A solution contains a mixture of 1 mole (mol) H2O, 2 mol ethanol (C2H5OH), and 1 mol acetaldehyde (CH3CHO) at 293 K...
When you look at the night sky, you can see that some stars are brighter than others as shown in this image of Orion. Two factors determine the brightness of a star: luminosity - how much energy it puts out in a given time distance - how far it is from us A searchlight puts out ...
How to determine if a pair of substances are likely to form a homogeneous solution? Describe a chemical test that can be carried out in order to distinguish between: What test could be performed to distinguish the following pair of compoun...
When we look into some of the physical properties of a substance, we may encounter the melting point (especially if the substance is solid). The melting point for each substance will be different because some have a very low melting point while other sub...
