(a)
Interpretation:
The balanced chemical equation for the reaction between butane and oxygen gas is to be stated.
Concept introduction:
A
Answer to Problem 68E
The balanced chemical equation for the reaction between butane and oxygen gas is shown below.
Explanation of Solution
Hydrocarbons react in the presence of oxygen to give carbon dioxide and water. This reaction is called combustion reaction. Butane reacts with oxygen to form carbon dioxide and water.
The unbalanced chemical equation for the reaction between butane and oxygen gas is as shown below.
The numbers of atoms of elements on the left side of the reaction are not equal to the right side of the reaction. Therefore, the reaction is unbalanced.
Butane is multiplied by the coefficient two, oxygen gas by thirteen. On the right side, carbon dioxide is multiplied by eight and water is multiplied by ten.
Therefore, the balanced chemical equation for the reaction between butane and oxygen gas is shown below.
The numbers of atoms of each element on the left side of the reaction are equal to the right side of the reaction. Therefore, the reaction is balanced.
The balanced chemical equation for the reaction between butane and oxygen gas has been stated.
(b)
Interpretation:
The balanced chemical equation for the heating of
Concept introduction:
A chemical reaction is a process in which rearrangement of atom or ions takes place between two reacting species. A balanced chemical equation represents an equation in which all the reactants and products are written with their stoichiometric coefficient and physical states. The number of atoms of an element on both sides of the equation is equal.
Answer to Problem 68E
The balanced chemical equation for the heating of
Explanation of Solution
A hydrated salt on heating evaporates water molecules to form anhydrous salt. Therefore, Cobalt acetate tetrahydrate on heating gives anhydrous cobalt acetate and water vapour.
The completed chemical equation of the reaction for the heating of
The numbers of atoms of elements on the left side of the reaction are not equal to the right side of the reaction. Therefore, the reaction is unbalanced.
Water molecule is multiplied by four for balancing the equation.
Therefore, the balanced chemical equation for the reaction for the heating of hydrated salt of sodium dichromate is shown below.
The numbers of atoms of each element on the left side of the reaction are equal to the right side of the reaction. Therefore, the reaction is balanced.
