Single-Displacement+Reactions


 * Single-Displacement Reactions:**

In a single-displacement reaction one element in a compound is replaced by another element of similar character.

The formula for a single-displacement reaction is A+BX > AX+B
 * The Formula:**

> Ex: When solid magnesium reacts with hydrochloric acid it produces hydrogen gas and aqueous magnesium chloride. > Ex: Mg(s) + HCL(aq) > H2(g) + MgCl2(aq) > Ex: Mg(s) + 2HCL(aq) -> H2(g) + MgCl2(aq)
 * Solving Single-Displacement Reaction Problems:**
 * 1) Like all reactions start with the sentence form
 * 1) Then convert the sentence into an equation
 * 1) Then simply balance the equation and the problem is good to go
