Do isomers have the same boiling point?
Isomers are molecules with the same chemical formula but different structures. Due to their different structures, isomers can have different boiling points.
What is the ranking of the following molecules based on their boiling points?
The ranking of molecules based on their boiling points is determined by their molecular weight and intermolecular forces. Generally, larger molecules with stronger intermolecular forces have higher boiling points.
How can one determine the boiling points of compounds?
The boiling points of compounds can be determined by considering the strength of the intermolecular forces between molecules. Compounds with stronger intermolecular forces, such as hydrogen bonding or dipole-dipole interactions, tend to have higher boiling points. Additionally, the size and shape of the molecules can also affect the boiling point. By analyzing these factors, one can predict and compare the boiling points of different compounds.
What physical properties are different for the isomers. explain.?
Isomers are molecules with the same molecular formula but different structural arrangements. Physical properties that can differ between isomers include boiling points, melting points, solubility, and density. These differences arise because the arrangement of atoms in isomers affects how the molecules interact with each other, leading to variations in physical properties.
What steps should a student follow to separate a mixture?
That would depend on the properties of the substances in the mixture. You can separate mixtures based on differences in boiling points by distillation. If the substances have different isoelectric points, they can be separated by ion-exchange chromatography. If the substances are made up of molecules of significantly different size, then each type of molecule can be separated by size-exclusion chromatography. There are many more examples of ways that mixtures can be separated, but without more information it's impossible to say which would be best for your particular scenario.
Why two different compound have different melting points?
because the arrangement of molecules are different in both.
What are the differences between bis-tris and tris-glycine buffer systems in terms of their suitability for protein electrophoresis?
Bis-Tris and Tris-Glycine buffer systems differ in their pH range and buffering capacity, affecting their suitability for protein electrophoresis. Bis-Tris has a narrower pH range and higher buffering capacity, making it more suitable for resolving proteins with different isoelectric points. Tris-Glycine has a wider pH range but lower buffering capacity, making it better for separating proteins with similar isoelectric points.
What is the temperature that a liquid turns into a solid?
different liquids have different freezing points. For water its 0 degrees Celsius but other liquids will have different freezing points because of the element that make it up and the size of its molecules first you need to pick a liquid, they all have different freezing points.
The isoelectric point of an amino acid is?
The isoelectric point of an amino acid is the pH at which the amino acid carries no net charge. It is the pH at which the amino acid exists in its zwitterionic form, with equal numbers of positive and negative charges.
Do isomers have the same boiling point?
Isomers are molecules with the same chemical formula but different structures. Due to their different structures, isomers can have different boiling points.
Why do you think some hydrocarbons are gases and others are liquid?
Different hydrocarbons have different boiling points (and melting points) depending on their molecular size: smaller molecules boil at lower temperatures, larger molecules boil at higher temperatures. This fact is used to refine petroleum by fractional distillation. Methane has very small molecules and is a gas. Gasoline, diesel fuel, and kerosene have medium size molecules and are liquids. Asphalt has large molecules and is solid.
Give some examples for barriers of communication?
Differing languages, different dialects, different social-economic groups, opposing points of view.differentin sex
What is the ranking of the following molecules based on their boiling points?
The ranking of molecules based on their boiling points is determined by their molecular weight and intermolecular forces. Generally, larger molecules with stronger intermolecular forces have higher boiling points.
Why do polar and nonpolar molecules have different properties?
Polar molecules have an uneven distribution of charge due to the presence of polar covalent bonds, leading to interactions like hydrogen bonding and higher boiling points. Nonpolar molecules have a more symmetrical distribution of charge, making them less interactive with other molecules and typically having lower boiling points.
How can one determine the boiling points of compounds?
The boiling points of compounds can be determined by considering the strength of the intermolecular forces between molecules. Compounds with stronger intermolecular forces, such as hydrogen bonding or dipole-dipole interactions, tend to have higher boiling points. Additionally, the size and shape of the molecules can also affect the boiling point. By analyzing these factors, one can predict and compare the boiling points of different compounds.
Does longer hydrocarbon molecules have higher boiling points than short hydrocarbon molecules?
yes
What societies had slavery?
Ancient Greece, Rome, the United States, and various African societies are examples of societies that practiced slavery at different points in history.
