a solution of lead(2)nitrate is added to hydrochloric acid. A precipitate is formed in a double displacement reaction
Question:how to balance this equation problem
To balance this equation, follow these steps:
Step 1: Write down the given chemical equation:
Pb(NO3)2 + HCl -> ?
Step 2: Break down the chemical compounds into their respective ions:
Pb(NO3)2 (Pb2+ and 2NO3-) + HCl (H+ and Cl-)
Step 3: Identify the possible products of the reaction: In this case, a double displacement reaction will occur. The positive ions will switch places, so Pb2+ will combine with Cl- and H+ will combine with NO3-.
Step 4: Write down the products:
Pb(NO3)2 + HCl -> PbCl2 + HNO3
Step 5: Check if the equation is already balanced. If not, proceed to step 6.
Step 6: Balance the equation by adjusting the coefficients in front of the chemical formulas to ensure that the number of atoms on both sides of the equation is equal.
Pb(NO3)2 + 2HCl -> PbCl2 + 2HNO3
Now the equation is balanced with two chlorine (Cl) atoms on both sides and two nitrogen (N) and six oxygen (O) atoms on both sides.
How? with ease?
Pb(NO3)2(aq) + 2HCl(aq) ==> PbCl2(s) + 2HNO3(aq)
I would like to point out that lead(2)nitrate is not the correct name. The 2 must be in Roman numerals; i.e., lead(II) nitrate. The old name is plumbous nitrate.
