(a)
Expert Solution
Interpretation Introduction
Interpretation:
The balanced equation reaction between rubidium and water has to be written.
Concept Introduction:
Chemical equation is the representation of a chemical reaction, in which the reactants and products of the reactions are represented left and right side of an arrow respectively by using their respective chemical formulas.
Reactant of a chemical reaction is the substrate compounds or the compounds which undergo a chemical reaction.
Product of a chemical reaction is the produced compounds or the compounds formed after a chemical reaction.
Balanced chemical equation of a reaction is written according to law of conservation of mass.
Rubidium (Rb) is an alkali metal with atomic number 37. The electronic configuration of rubidium is [Kr]5s1
Answer to Problem 8.123QP
The balanced equation reaction between rubidium and water can be given as:
2Rb(s)+2H2O(l)→2RbOH(aq)+H2(g)
Explanation of Solution
Rubidium reacts with water to give RbOH and molecular hydrogen. Reaction can be given as:
Rb(s)+H2O(l)→RbOH(aq)+H2(g)
Here, the number of each element on both sides is made equal by giving the coefficient 2 for the reactant Rb and product RbOH. Also the coefficient 2 is given to H2O so that the number of elements on both sides becomes equal.
Therefore,
The balanced equation reaction between rubidium and water can be given as:
2Rb(s)+2H2O(l)→2RbOH(aq)+H2(g)

Answer to Problem 8.123QP
The balanced equation reaction between rubidium and Cl2 can be given as:
2Rb(s)+Cl2(g)→2RbCl(s)
Explanation of Solution
Rubidium reacts with Cl2 to give RbCl. Reaction can be given as:
Rb(s)+Cl2(g)→RbCl(s)
Here, the number of each element on both sides is made equal by giving the coefficient 2 for the reactant Rb and product RbCl.
Therefore,
The balanced equation reaction between rubidium and Cl2 can be given as:
2Rb(s)+Cl2(g)→2RbCl(s)
