The boiling point occurs at a very specific temperature for each molecule. That is why it is often used to identify an unknown substance in qualitative chemistry. The reason that the boiling point is predictable is because it is controlled by thestrength of the bondsholding the atoms in the m...
For a given element, the mass (in grams) of one mole is given by its mass number on the periodic table; the "molar mass" of a molecule is the sum of the molar masses of the elements in the molecule in the correct ratios. It is simple to determine the molar mass of elements and ...
What does 'like dissolves like' mean in terms of solubility? How do you determine the polarity of a molecule? Why is it important to draw Lewis structures when determining solubility? What is the solubility of pyridine in water? How does the polarity of DMSO affect its solubility ...
Explain why the boiling point of CH3CONH2 (221 degrees C) is significantly higher than the boiling point of CH3CO2H (118 degrees C). What happens when sodium chloride is added to boiling water and why? How to perform an experiment to determine the effect that sodium chloride on the boili...
How are the boiling point and melting point of a molecule related to how the molecule reacts or breaks down? Indicate which molecule has a higher boiling point. Also, indicate which force is responsible for the difference (dispersion, H-bonding, or dipolar). a) PH3 b) AsH3 ...
Showing molecule sizes is important because the size of solid particles in a colloid helps determine its properties. The particles dispersed in milk range from 3.9 x 10-8to 3.937 x 10-5inches (1 x 10-7to 1 x 10-4centimeters) in diameter. ...
Since water is a ubiquitous liquid and solvent, it is worth investigating the factors that determine its vapor pressure equation in more detail. Water has a Pvaporof 0.031 atm, or less than 1/30th of atmospheric pressure. This helps explain its relatively high boiling point for such a simple...
The boiling point of sulfur dioxide is {eq}- 10{\rm{^\circ C}} {/eq}. Sulfur dioxide is heavier than air. It is very harmful to the eyes. Answer and Explanation:1 To check whether the gas is sulphur dioxide or not. The gas of sulfur dioxide is passed through the piece of paper...
A chemistry professor is conducting an experiment to determine the boiling point of hexane. She sets up a distillation apparatus and begins heating the hexane solution. As the temperature rises, she notices that the boilin... #Math 3 Videos ...
Titration is used to determine the concentration of an unknown substance via the molar relationship expressed through the chemical reaction equation. Using these relationships, the pH value can be determined by calculating the concentration of hydrogen i
