Question

bufotenin is a toxin isolated from the skin of toads, particularly the colorado river toad. the psychedelic compound is in fact a potent toxin and has lead to many deaths. symptoms of bufotenin poisoning can include pain, trouble breathing, and impaired blood circulation, which has been reported to give the consumer a purple appearance. take a look at the combustion reaction involving bufotenin below. what pattern do combustion reactions follow? $c_{12}h_{16}n_{2}o_{(s)}+15.5o_{2(g)}\to12co_{2(g)}+8h_{2}o_{(g)}+n_{2(g)}+$ heat $ab + o_2\to ao_x + bo_y$ $ab\to a + b$ $a + b\to ab$ $ab + c\to ac + b$ $ab + cd\to ad + bc$

Explanation:

• Combustion reactions typically involve a substance (here \(C_{12}H_{16}N_2O\) represented as \(AB\)) reacting with oxygen (\(O_2\)).
• The general form of a combustion reaction is \(AB + O_2

ightarrow AO_x+BO_y\) (where \(AO_x\) and \(BO_y\) are the oxidized products of the elements in \(AB\)). For example, in the given reaction \(C_{12}H_{16}N_2O\) (\(AB\)) reacts with \(O_2\) to form \(CO_2\) (\(AO_x\) where \(A = C\), \(x = 2\)), \(H_2O\) (\(BO_y\) where \(B = H\), \(y=1\) for \(H_2O\) written as \(H_2O\) which is equivalent to \(H_2O_1\)) and \(N_2\) (since nitrogen in \(C_{12}H_{16}N_2O\) also gets oxidized in a sense of forming a stable product \(N_2\)).

• Let's analyze other options:
• \(AB

ightarrow A + B\) is a decomposition reaction (breaking of a single compound into simpler substances).

• \(A + B

ightarrow AB\) is a combination reaction (two or more substances combining to form a single compound).

• \(AB + C

ightarrow AC + B\) is a single - displacement reaction (one element displaces another in a compound).

• \(AB+CD

ightarrow AD + BC\) is a double - displacement reaction (exchange of ions between two compounds).

Answer:

A. \(AB + O_2
ightarrow AO_x+BO_y\)
