The patiwnts may develop reactions when a contrast is injected in to vein for examination.This can be allergic type (iodine ) or due to contrast induced nephropathy
The contrast reactions can be categorised into three
List 3 contrast reactions that may occur and the category of the reaction,
3. For each of the following reactions, respond to the following: a. Does a reaction occur when aqueous solutions of barium hydroxide and nickel(II) bromide are combined?(Yes/No) If a reaction does occur, write the net ionic equation. (specify states) b. Does a reaction occur when aqueous solutions of sodium sulfide and magnesium bromide are combined?(Yes/No) If a reaction does occur, write the net ionic equation. (specify states)
Reactions which occur may be described in a particular way. Explain the best option. Transamination of aspartate produces oxaloacetate. This is an example of: substrate level phosphorylation a fermentation reaction a cataplerotic reaction an anaplerotic reaction
1. Under second-order conditions (strong base/nucleophile),
SN2 and E2 reactions may occur simultaneously and
compete with each other.
Show what products might be expected from the reaction of
2-bromo-3-methylbutane (a moderately hindered 2∘ alkyl halide) with
sodium ethoxide.
