Question

what is the general form of a single displacement reaction for a metal reacting with an ionic compound? a) a + bx→ax + b b) a + bx→abx c) ax + by→ay + bx d) ax + by→ab + xy a b c d write the skeleton equation for the reaction in which solid iron(ii) oxide reacts with oxygen gas to form solid iron(iii) oxide. a) feo(s) + o(g)→fe3o4(s) b) feo(s) + o(g)→fe2o3(s) c) fe2o3(s) + o2(g)→fe3o4(s) d) feo(s) + o2(g)→fe2o3(s)

Explanation:

1. For the first question, in a single - displacement reaction where a metal (A) reacts with an ionic compound (BX), the metal displaces another element in the compound. The general form is \(A + BX

ightarrow AX + B\).

1. For the second question, solid iron(II) oxide is \(FeO\), oxygen gas is \(O_2\), and solid iron(III) oxide is \(Fe_2O_3\). The skeleton equation for the reaction of solid iron(II) oxide with oxygen gas to form solid iron(III) oxide is \(FeO(s)+O_2(g)

ightarrow Fe_2O_3(s)\).

Answer:

1. A. \(A + BX

ightarrow AX + B\)

1. D. \(FeO(s)+O_2(g)

ightarrow Fe_2O_3(s)\)
