Chemical Equation Practice
NAME:
DATE:
Chemical equations use symbols to describe reactions. Reactants go on the left, products on the right. Be sure to include subscripts for molecules and coefficients for balancing.
1 WORDS → SYMBOLS
1. Two molecules of hydrogen gas react with one molecule of oxygen gas to produce two molecules of dihydrogen monoxide.
2. One atom of solid carbon reacts with one molecule of oxygen gas to yield one molecule of carbon dioxide.
3. Two units of solid sodium react with one molecule of chlorine gas to produce two units of solid sodium chloride.
2 SYMBOLS → WORDS
2Mg(s) + O2(g) → 2MgO(s)
CH4(g) + 2O2(g) → CO2(g) + 2H2O(g)
Reaction Checklist
Coefficients correctly placed?
Reactants on left, Products on right?

Correct translations. Note: Students should include state symbols (s, l, g) based on problem descriptions.
1 WORDS → SYMBOLS
1. Hydrogen gas + oxygen gas → water.
2H2(g) + O2(g) → 2H2O(l)
2. Solid carbon + oxygen gas → carbon dioxide.
C(s) + O2(g) → CO2(g)
3. Solid sodium + chlorine gas → solid sodium chloride.
2Na(s) + Cl2(g) → 2NaCl(s)
2 SYMBOLS → WORDS
2Mg(s) + O2(g) → 2MgO(s)
Two atoms of solid magnesium react with one molecule of oxygen gas to produce two units of solid magnesium oxide.
CH4(g) + 2O2(g) → CO2(g) + 2H2O(g)
One molecule of methane gas reacts with two molecules of oxygen gas to produce one molecule of carbon dioxide gas and two molecules of water vapor (gas).
