Question

QUESTION 10The combustion of ammonia in the presence of excess oxygen yields NO2 and H₂O.4 NH3 (g) + 7 02 (g) →4 NO2 (g) + 6 H2O (g)If 34.0 g of ammonia (NH3) is consumed, how many moles of oxygen will be consumed?2.0 moles4.0 moles7.0 moles14 moles3.5 moles

Answer 1

Single displacement reaction ---- Option A

Step-by-step explanation

Given that;

`\text{ 2AlCl}_(3(aq))\text{ }+\text{ 3Br}_(2(l))\text{ }\rightarrow\text{ 2AlBr}_(3(aq))+3Cl_(2(aq))`

In the reaction above, Chlorine displaced bromine, this is possible because chlorine is more reactive than bromine.

The above reaction is an example of a single displacement reaction.

Single displacement reaction is a type of reaction in which an element displaces another element in the compound to produce a new compound and the displaced element.

Hence, the correct answer is option A
