Answer:
Polymeric MDI is a mixture of. monomeric MDI as well as larger molecular weight oligomers of MDI, and is a brownish. liquid at room temperature and may have a slight odor. Commercial MDI products are. often mixtures of monomeric and polymeric MDI and can contain other additives as well.

Answer:
The relative conjugate acids and bases are listed below:
CH3NH2 → CH3NH3+
H2SO3→ HSO3-
NH3→ NH4+
Explanation:
In a Brønsted-Lowry acid-base reaction, a conjugate acid is the species resulting from a base accepting a proton; likewise, a conjugate base is the species formed after an acid has donated a hydrogen atom (proton).
To this end:
- HSO3- is the conjugate acid of H2SO3 i.e sulfuric acid has lost a proton (H+)
- NH4+ is the conjugate acid of NH3 i.e the base ammonia has gained a proton (H+)
- OH- is the conjugate base of H20
- CH3NH3+ is the conjugate base of the base CH3NH2 methylamine
Answer: The heat transfer by convection requires a solid-fluid interface, a temperature difference between the solid surface and the surrounding fluid and a motion of the fluid. The process of heat transfer by convection would occur when there is a movement of macro-particles of the fluid in space from a region of higher temperature to lower temperature.
