Answer:
Intermolecular forces (IMF) (or secondary forces) are the forces which mediate interaction between atoms, including forces of attraction or repulsion which act between atoms and other types of neighboring particles, e.g. atoms or ions. Intermolecular forces are weak relative to intramolecular forces – the forces which hold a molecule together. For example, the covalent bond, involving sharing electron pairs between atoms, is much stronger than the forces present between neighboring molecules. Both sets of forces are essential parts of force fields frequently used in molecular mechanics.
Explanation:
The electron gain for iron means that it is reduced (answer C)
Explanation
Redox reaction is made up of two halves.
That is a reduction half and a oxidization half.
In the reduction half electrons are gained which result to decrease in oxidation number.
In the Oxidization half electrons are lost which result to increase in oxidation number.
iron is therefore reduced since it gains electrons
Answer:
20, 50, 25
Explanation:
I just figured it out somehow in my brain.
Answer:
The correct answer is b the magnitude of the concentration gradient of the molecule.
Explanation:
Dffusion is one of most important membrane transport process that allow several molecules such as gases oxygen and carbon dioxide to pass directly across the plasma membrane.The is no involvement of carrier proteins or ion channels during passive diffusion.
During passive diffusion molecules are transported along their concentration gradient that means from the region of high concentration to region of low concentration,until the concentration of both regions become same.
