07 Skeleton Equations Worksheet 3q65d

Skeleton Equations Skeleton Equations are equations that are unbalanced, meaning they do not have an equal amount of each element on both sides of the equation Symbols to indicate state of compound: (s) – solid (g) – gas (l) – liquid (aq) – aqueous (dissolved in water)

Any diatomic element found by itself must have a subscript of 2! Task #1: Covert the following word equations to skeleton equations. Be sure to include to state of matter that each compound as a subscript. Also, state the type of reaction that takes place. Example: Silver nitrate + copper  silver + copper nitrate Solution: AgNO3 (aq) + Cu(s)  Ag(s) + Cu(NO3)2 (aq)

This is a single displacement reaction

(a) Iron + sulphur  Iron(II) sulphide ____________________________________________________________________________________ (b) Hydrogen gas + chlorine gas  hydrogen chloride ____________________________________________________________________________________ (c) Magnesium + oxygen gas  magnesium oxide ____________________________________________________________________________________ (d) Aluminum oxide  aluminum + oxygen gas ____________________________________________________________________________________ (e) Hydrogen gas + oxygen gas  water ____________________________________________________________________________________ (f) Hydrochloric acid + sodium hydroxide  sodium chloride + water ___________________________________________________________________________________ (g) Methane gas + oxygen gas  carbon dioxide + water ____________________________________________________________________________________ (h) Potassium hydroxide + hydrogen bromide  potassium bromide + water ____________________________________________________________________________________ (i) Carbon + oxygen gas  carbon dioxide ____________________________________________________________________________________ (j) Tin (II) oxide + hydrogen gas  tin + water ____________________________________________________________________________________ (k) Write your own word equation, then write the skeleton equation for it

(l) Write your own word equation, then write the skeleton equation for it
