**Na₂C₂O₄(aq) + Pb(NO₃)₂⇒PbC₂O₄(s) + 2NaNO₃(aq)**

<h3>Further explanation</h3>

**Given**

Word equation

**Required**

Balanced equation

**Solution**

Convert to skeleton equation

Na₂C₂O₄(aq) + Pb(NO₃)₂⇒PbC₂O₄(s) + NaNO₃(aq)

Balanced equation

Give a coefficient

Na₂C₂O₄(aq) + aPb(NO₃)₂⇒bPbC₂O₄(s) + cNaNO₃(aq)

Make an equation

C, left = 2, right =2b⇒2b=2⇒**b=1**

Na, left = 2, right = c⇒**c=2**

O, left = 4+6a, right = 4b+3c⇒4+6a=4b+3c⇒4+6a=4.1+3.2⇒6a=6⇒**a=1**

**The equation becomes :**

Na₂C₂O₄(aq) + Pb(NO₃)₂⇒PbC₂O₄(s) + 2NaNO₃(aq)

**Answer:saturated **

**Explanation: they can be mixed together **

We can't answer without the following

14 as well. A neutral atom has just as many protons in its nucleus and electrons it is electronic shells.
