(a)
Interpretation: The balanced equation for the reaction of glucose with oxygen gas producing gaseous carbon dioxide and water vapour is to be stated.
Concept introduction: The species on left side of any chemical equation are reacting species and that of right side are product species. The basic condition for balanced equation is that atoms of every element present on two reaction sides must be equal. In order to satisfy this condition, some numerical values are added to balance the respective atoms of different elements.
(b)
Interpretation: The balanced equation for the reaction of solid iron (III) sulfide with hydrogen chloride forming solid iron (III) chloride and hydrogen sulfide gas is to be stated.
Concept introduction: The species on left side of any chemical equation are reacting species and that of right side are product species. The basic condition for balanced equation is that atoms of every element present on two reaction sides must be equal. In order to satisfy this condition, some numerical values are added to balance the respective atoms of different elements.
(c)
Interpretation: The balanced equation for the reaction of carbon disulfide liquid with ammonia gas producing hydrogen sulfide gas and solid ammonium thiocyanate is to be stated.
Concept introduction: The species on left side of any chemical equation are reacting species and that of right side are product species. The basic condition for balanced equation is that atoms of every element present on two reaction sides must be equal.
