Concept explainers
(a)
Interpretation:
The reaction between solid tetraphosphorus trisulfide and oxygen gas to form solid tetraphosphorus decoxide and sulfur dioxide gas is to be shown in terms of molecules.
Concept introduction:
In a balanced chemical equation, the total mass of reactants and products are equal in a balanced chemical equation, thus, it obeyed the law of conservation of mass. Also, the amounts of substances in a balanced
The coefficients in the balanced equation tell about the number of molecules or moles of each reactant and product involved in the reaction.
(b)
Interpretation:
The reaction between solid tetraphosphorus trisulfide and oxygen gas to form solid tetraphosphorus decoxide and sulfur dioxide gas is to be shown in terms of moles.
Concept introduction:
In a balanced chemical equation, the total mass of reactants and products are equal in a balanced chemical equation, thus, it obeyed the law of conservation of mass. Also, the amounts of substances in a balanced chemical reaction are stoichiometrically equivalent to each other.
The coefficients in the balanced equation tell about the number of molecules or moles of each reactant and product involved in the reaction.
(c)
Interpretation:
The reaction between solid tetraphosphorus trisulfide and oxygen gas to form solid tetraphosphorus decoxide and sulfur dioxide gas is to be shown in terms of grams.
Concept introduction:
In a balanced chemical equation, the total mass of reactants and products are equal in a balanced chemical equation, thus, it obeyed the law of conservation of mass. Also, the amounts of substances in a balanced chemical reaction are stoichiometrically equivalent to each other.
The coefficients in the balanced equation tell about the number of molecules or moles of each reactant and product involved in the reaction.
The formula to calculate the mass is as follows:
