Here are the balanced equations for each of the reactions you specified:
(A) **Rubidium reacts with oxygen:**
Rubidium (Rb) reacts with oxygen (O₂) to form rubidium oxide (Rb₂O).
\[
4 \text{Rb} + \text{O}_2 \rightarrow 2 \text{Rb}_2\text{O}
\]
(B) **Barium reacts with fluorine:**
Barium (Ba) reacts with fluorine (F₂) to form barium fluoride (BaF₂).
\[
\text{Ba} + \text{F}_2 \rightarrow \text{BaF}_2
\]
(C) **Indium reacts with oxygen:**
Indium (In) reacts with oxygen (O₂) to form indium(III) oxide (In₂O₃).
\[
4 \text{In} + 3 \text{O}_2 \rightarrow 2 \text{In}_2\text{O}_3
\]
(D) **Lead reacts with hot concentrated hydrochloric acid:**
Lead (Pb) reacts with hydrochloric acid (HCl) to form lead(II) chloride (PbCl₂) and hydrogen gas (H₂).
\[
\text{Pb} + 2 \text{HCl} \rightarrow \text{PbCl}_2 + \text{H}_2
\]
(E) **Magnesium chloride hexahydrate is heated to drive off water of crystallization:**
When magnesium chloride hexahydrate (MgCl₂·6H₂O) is heated, it becomes anhydrous magnesium chloride (MgCl₂) and water (H₂O).
\[
\text{MgCl}_2 \cdot 6\text{H}_2\text{O} \rightarrow \text{MgCl}_2 + 6 \text{H}_2\text{O}
\]
