A student investigates the dissolution of ammonium chloride in water as the basis of an instant cold pack, in which solid ammonium chloride is kept apart from water by a thin membrane. The enthalpy change when one mole of solid ammonium chloride dissolves in…
Solid ammonium chloride decomposes when heated to form two gases, ammonia and hydrogen chloride. (i) Write the chemical equation for this decomposition. (ii) Calculate the volume of ammonia produced at STP when an 8.00 g sample of ammonium chloride decomposes.…
Iodine crystals placed in a warm flask turn directly into purple vapour without forming a liquid. Which term describes this change of state? A. Boiling B. Evaporation C. Deposition D. Sublimation
Compound P contains two amino groups outside the ring system: one bonded directly to the ring and one at the end of the side chain. State which of these is a secondary amino group, giving a reason.
Compare, giving a reason, the length of a carbon–nitrogen bond within the quinazoline ring system with the length of a carbon–nitrogen bond in the diethylamino group.
The N–H bonds in compound P and the O–H bonds in water are both polar. State, giving a reason, whether nitrogen or oxygen is the more electronegative element.
Compound P can be synthesized by reacting 4,6-dichloroquinazoline with another reactant, B. (i) Deduce the structure of B. (ii) The reaction can be catalysed by copper(I) iodide, CuI. State the ground-state electron configuration of the Cu+ ion.…
How many moles of carbon dioxide are produced by the complete combustion of 14.5 g of butane, C4H10? Mr = 58 A. 0.25 B. 0.50 C. 1.00 D. 1.25
State the ground-state electron configuration for Ni2+.
