A larger molecule is more polarizable, which is an attraction that keeps the molecules together. They need more energy to escape to the gas phase, so the larger molecule has the higher boiling point. Compare sodium nitrate and rubidium nitrate in terms of molecular weight and boiling point: Fa...
In chemistry, a mole is a quantity used relate reactants to products in stoichiometric equations. A mole of any substance is equal to 6.02 x 10^23 particles -- usually atoms or molecules -- of that substance. For a given element, the mass (in grams) of o
When is the boiling point of a liquid equal to its normal boiling point? Explain. If the intermolecular forces between molecules of a substance were very small, what effect would you expect this to have on the boiling point and vapor pressure of ...
I'm going to use this opportunity to teach you about some really weird molecules that you're going to see for the rest of organic chemistry, and maybe this will give you an opportunity to get a little bit more familiar with them. Alright? So let me go ahead and introduce th...
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 boiling point of water? Why does NH_3 have a lower boiling point than H_2O? Briefly explain why you should not add boiling chips to a ...
Indicate which molecule has a higher boiling point. Also, indicate which force is responsible for the difference (dispersion, H-bonding, or dipolar). a) F2 b) HCl Explain the effects of the polarity of molecules on boiling point. For which of the following molecules would the intermol...
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...
What is the strength of the stuff you would normally buy at a store? Its no 38.5%.. is 38.5% a "big" number in this context? how would I determine the molarity of this solution I have made? I cant thank you guys enough for the help, and tolerance to my chemistry n00bness...
The sulfur dioxide is used as the beaching agent of food. It is also used as a refrigerant to cool the substances in the refrigerant. 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. ...
the liquid-vapor mixture and the vapor itself to determine the boiling point of the two or more components of the compound. Many distillation apparatus setups will automatically measure the temperature throughout the heating of the experiment. This can give you a continuous set of data points ove...
