We have learnt that the conjunction and implies addition (+).
Let’s consider following question from a chemistry test.
Balance the equation for the following reaction:
- Sodium hydroxide and ammonium chloride form ammonium chloride, ammonia and water.
|Step||Grammatical analysis||Language of chemistry|
|1||Compound subject is implied by and.||There are two reactants.
Implication: Place these reactants side-by-side on a line. Replace and by a +.
|2||Form is in present tense, a plural action verb.||In a chemical equation, form can be depicted by the symbol →.
Other action verbs which stand for the symbol are as follows:
Implication: Substitute these action verbs with →.
|3||The words in green are the direct objects.||There are three products. As seen in the sentence, products are placed to the right of the arrow.
Implication: Place these products to the right of the arrow.
|4||The commas and and implies that the direct objects are compound.
No. of objects = No. of commas + and + 1 (UK punctuation)
|In the equation, following substitutions can be made:
, = +
and = +
Therefore, the word equation can be written as follows:
Sodium hydroxide and ammonium chloride form sodium chloride, ammonia and water
Sodium hydroxide + ammonium chloride → sodium chloride + ammonia + water
Its chemical equation:
NaOH + NH4Cl → NaCl + NH3↑ + H20
Write an equation to describe the reaction which occurs when propane burns.
when clause = subject + predicate = propane burns
Burns (an action verb) = combines with O2
C3H8 + 5O2 → CO2 + H20
Write an equation for the formation of sulphur trioxide from oxygen and sulphur dioxide.
|Word/phrase||Interpretation in chemistry|
|from||the reactants follow|
|and (implies plural)||more than one reactant|
|for the formation of||singular product|
O2 + 2SO2 → 2SO3
|Is grammar applicable in chemistry or other sciences?
Yes, it is.
