Urinary tract infection. Urine discoloration - it might not be blood in the urine. Red urine - see also other causes of red urine or orange urine than blood in urine. Pink urine - small quantities of blood in urine may appear as pink urine. Kidney (renal) conditions Kidney infection.
Intramolecular force. An intramolecular force is any force that holds together the atoms making up a molecule or compound. They contain all types of chemical bonds. They are stronger than intermolecular forces, which are present between atoms or molecules that are not bonded. Types of intramolecular force.
The intermolecular forces of attraction considered here are: Van der Waals' forces; permanent dipole-permanent dipole interactions; hydrogen bonding; Van der Waals' forces. Van der Waals' forces are forces of attraction which exist between all atoms and molecules. Van der Waals' forces are much weaker than all other types of bonding. They are only significant in atoms and molecules which have no other types of intermolecular forces of attraction, for example, discrete non-polar molecules and the Group 0 elements.
