When the molecules are attracted to a charged wand are they polar or nonpolar?
The molecules attracted to a charged wand are most likely polar molecules. Polar molecules have uneven distribution of charge which allows them to interact with other charged objects, such as a charged wand. Nonpolar molecules have a more symmetric charge distribution and are less likely to be attracted to a charged wand.
How do you break compounds into ions?
only compounds with the (aq) state symbol
Is CaCl non-polar?
it is a salt and therefore ionic is is however slightly soluble in polar solutions
In a symmetrical molecule do the dipole charges cancel out and make the molecule nonpolar?
Yes, in a symmetrical molecule where the dipole moments generated by individual bonds cancel each other out due to symmetry, the overall molecule is nonpolar. This occurs when the molecule has a symmetric shape or an equal distribution of charge.
Why do some compounds have no charge?
Strictly, all compounds have no charge. What would be a compound if neutral but actually has a charge should properly be called an ion. Some compounds, such as the diatomic molecules of the elements hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine, have perfectly symmetrical covalent bonds without even any polarity. Most covalent bonds between dissimilar atoms have some polarity, as do all ionicly bonded compounds, but this does not mean that the compounds themselves have net electrical charge.
When is it valid to approximate a charge distribution by a point charge?
A charge distribution can be approximated as a point charge when the distance from the charge to the point of interest is much larger than the size of the charge distribution itself. This is often valid when the charge distribution is symmetric and the point of interest is located far away, allowing the electric field to be treated as originating from a single point. Additionally, if the total charge of the distribution is known, it can simplify calculations in electrostatics.
Electric field inside the cylinder which is cylindrically symmetric?
For a cylindrically symmetric charge distribution, the electric field inside the cylinder is also cylindrically symmetric. This means that the electric field points radially outwards or inwards along the axis of the cylinder with the magnitude dependent on the charge distribution. The electric field can be calculated using Gauss's law and applying symmetry arguments to simplify the problem.
What type of charge do compounds have-?
Compounds can have a neutral charge, a positive charge (cation), or a negative charge (anion), depending on the distribution of electrons within the atoms that make up the compound.
Is water a symmetric compound?
Yes, water is a symmetric compound with a bent molecular geometry. This means that the oxygen atom is at the center and the two hydrogen atoms are located on one side, resulting in an uneven distribution of charge within the molecule.
Are all ionic compounds Almost all ionic compounds are soluble in water?
Almost all. Some such as calcium carbonate, silver chloride are not soluble. Generally ionic compounds are soluble in water due to their ionic bonds which makes them easy to dissociate in polar solutions such as water.
Why can have an isolated atom not have a permanent electric dipole moment?
An isolated atom cannot have a permanent electric dipole moment because its charge distribution is spherically symmetric, meaning the positive and negative charges are evenly distributed. A dipole moment requires separation of positive and negative charges, which is not present in a spherically symmetric distribution.
Why are many sulphate compounds soluble but some are not?
If you mean why are they soluble in water, it is because the hydrogen in water has a slight positive charge and the oxygen in water has a slight negative charge, making an ionic compound (such as one containing sulphate) which has charges itself, readily soluble to adjoin these charges.
What is the relationship between polarity and polarizability in chemical compounds?
Polarity in chemical compounds refers to the distribution of charge within the molecule, while polarizability is the ability of a molecule to be distorted by an external electric field. Generally, compounds with higher polarity tend to have higher polarizability because the distribution of charge allows for easier distortion of the electron cloud.
What is the effect of sodium bicarbonate pH in water on the solubility of certain compounds?
The pH level of water with sodium bicarbonate can affect the solubility of certain compounds. When the pH is higher, some compounds may become more soluble, while others may become less soluble. This is because pH can influence the charge of molecules, which in turn affects their ability to dissolve in water.
When the molecules are attracted to a charged wand are they polar or nonpolar?
The molecules attracted to a charged wand are most likely polar molecules. Polar molecules have uneven distribution of charge which allows them to interact with other charged objects, such as a charged wand. Nonpolar molecules have a more symmetric charge distribution and are less likely to be attracted to a charged wand.
Why don't polar compounds mix with nonpolar compounds?
Polar compounds have poles that have a partial positive charge and a partial negative charge that attract other polar molecules. Nonpolar compounds do not have partially charged poles, so the polar substance is not attracted to them and they don't dissolve.
C2H2 polar or nonpolar?
C2H2 (Ethyne or Acetylene) is nonpolar because the molecule has a linear geometry with symmetric electronegativity, resulting in an equal distribution of charge and no net dipole moment.
