What else can I help you with?
Are ions of alkali metals larger or smaller than ions of alkaline metals from the same period?
larger
What are smaller than cells but larger than atoms?
Molecules are smaller than cells but larger than atoms. They are composed of atoms bonded together to form a distinct structure.
When NaCI dissolves in water does it give ions or molecules or both?
Ions. NaCl is a molecule. And when put in water the polar quality of the water molecules pull apart the na and the cl into ions.
Can sulfate ions and starch molecules be separated by a semipermeable membrane?
No, sulfate ions and starch molecules cannot be separated by a semipermeable membrane because of their differing sizes. Sulfate ions are small enough to pass through the pores of a typical semipermeable membrane, while starch molecules are much larger and cannot permeate the membrane. Therefore, a semipermeable membrane would allow sulfate ions to pass through while retaining the starch molecules on one side.
How do ions become molecules?
Ions and molecules are the results of two different types of bonds. Ions are the result of ionic bonds and molecules are the result of covalent bonds.
Are ions of alkali metals larger or smaller than ions of alkaline metals from the same period?
larger
Are ions of alkali metals larger or smaller than ions of alkaline earth metals from the same period?
larger
Are ions of alkali metals larger or smaller than ions or alkaline earth metals from the same period?
larger
Why are molecules called ions rather than atoms?
YOU
Ions that are made of more than one atom are examples of what?
Ions made up of more than one atom are called polyatomic ions.
Are non metallic ions smaller than the atoms?
no they are larger
What are smaller than cells but larger than atoms?
Molecules are smaller than cells but larger than atoms. They are composed of atoms bonded together to form a distinct structure.
Are metals ions larger or smaller than neutral atoms they came from?
Metal ions are smaller than the neutral atoms they came from.
Nonmetal ions larger than their elemental counterparts?
Non metallic ions are negatively charged. They have more electrons than protons. So they are larger than elemental counterparts that have equal number of protons and electrons.
Is cell larger than molecule?
Cells are larger than molecules. Cells normally have molecules inside them and constantly passing through their membranes. Cells normally contain water molecules along with glucose and other molecules.
When NaCI dissolves in water does it give ions or molecules or both?
Ions. NaCl is a molecule. And when put in water the polar quality of the water molecules pull apart the na and the cl into ions.
Why is it impossible to separate salt and water through a filter?
The salt is dissolved in the water at an atomic level. The holes in the filter are at a macroscopic level. It would be the equivalent of trying to prevent flies from getting into a building that has an open window the size of a football field. This is different than separating dust or coffee grinds from water because those items are macroscopic just like the filter is. If, in theory you could create a filter that was small enough to keep the Sodium Ions (they are smaller than the Chloride Ions) on on the same side, it would also prevent the water molecules from going through because water molecules are larger than sodium ions. A reverse filter would not work, because the chloride ions are larger than the water molecules. Thus the filter would be ineffective, either way.
