Will water dissolve in ionic or covalent compounds?
Water is a liquid and is usually considered to be the solvent. Water dissolves solutes. Many ionic compounds, but not all, are soluble in water. Water has negative and positive areas on the molecule so it is ideally suited to dissolving the negative and positive ions of an ionic substance. Purely covalent compounds, non-polar, are not supported by water so do not dissolve. Purely covalent, non-polar compounds have no negative and positive areas for the water to support.
What is a molecule with partially charged areas?
A molecule with partially charged areas is called a polar molecule. This occurs when there is an uneven distribution of electrons, causing one end of the molecule to have a slight positive charge and the other end to have a slight negative charge. Examples include water (H2O) and ammonia (NH3).
Why does methane not react with reagents such as nucleophiles?
quick answer is that nucleophiles like positive areas of molecules and electrophiles like negative areas of a molecule. In methane (CH4) the hydrogen and carbon have similar electronegativities and therefore there are no real positive and negative centres. Hope this helps mate
Why can oxygen diffuse across a membrane?
Oxygen is a small, nonpolar molecule that can easily pass through the lipid bilayer of cell membranes by simple diffusion without the need for a specific transport protein. This allows oxygen to move from areas of high concentration to areas of low concentration, such as from the lungs into the bloodstream.
What phosphate is polar?
Phosphate ions (PO4^3-) are polar due to the presence of both positively and negatively charged areas. The oxygen atoms carry a partial negative charge, while the central phosphorus atom carries a partial positive charge, making the molecule overall polar.
What describes materials that have a separated positive and negative areas?
materials that have a separated positive and negative areas are called Polarmaterials that doesnt have no separated positive or negative is called Nonpolar
Do no polar materials have separated positive and negative areas?
No, non-polar materials do not have separated positive and negative areas. In non-polar molecules, the electron distribution is even, meaning there are no distinct regions of partial positive or negative charge. This uniform distribution results in a lack of dipole moment, making non-polar materials generally hydrophobic and unable to interact favorably with polar solvents like water.
Is rubber polar or nonpolar?
Rubber is considered nonpolar because it is composed mainly of hydrocarbons which have symmetrical molecular structures. This symmetry leads to an even distribution of charge and no distinct positive or negative areas, resulting in a nonpolar molecule.
Do different areas of a thunderstorm cloud have positive and negative charges?
yes because it is high and low, and high and low are like positive and negative.
What characteristic is created by repeating positive shapes in space surrounded by negative areas of space.?
The characteristic created by repeating positive shapes in space surrounded by negative areas is known as a pattern or rhythm. This arrangement emphasizes the positive shapes, drawing the viewer's attention to their form and creating a visual balance with the negative spaces. The interplay between the positive and negative areas can also enhance depth and movement within the composition, adding visual interest and complexity.
What are the two types of pressure areas on the transparency?
the two types of pressure areas on the transparency are high and low pressure
Why does electrical current always flow from areas of negative charge to areas of positive charge The current is made up of electrons that carry negative charge and are pulled toward positive charge.?
Electrons are negatively charged particles that are attracted to positive charges. This attraction causes the flow of electrons (electric current) from areas of negative charge to areas of positive charge. This flow occurs because electrons naturally move to balance out the charge distribution in a system.
