You can explain what it means...like how gas tends to expand when heated and just tie it up with the sentence you want to make....(i dont know if that was helpful?)
Answer:
Pb(NO3)2(aq) + 2NaCl(aq) —> PbCl2(s) + 2NaNO3(aq)
Explanation:
When lead (II) nitrate, Pb(NO3)2 undergoes a double displacement reaction with aqueous sodium chloride, NaCl, the following products are obtained:
Pb(NO3)2(aq) + NaCl(aq) —>
Aqueous Pb(NO3)2 will dissociate in solution as follow:
Pb(NO3)2(aq) —> Pb2+(aq) + 2NO3-(aq)
On the other hand, aqueous NaCl will dissociate as follow:
NaCl(aq) —> Na+(aq) + Cl-(aq)
The double displacement reaction will take place as follow:
Pb(NO3)2(aq) + NaCl(aq) —>
Pb2+(aq) + 2NO3-(aq) + Na+(aq) + Cl-(aq) —> Pb2+(aq) Cl-(aq) + Na+(aq) 2NO3-(aq)
Pb(NO3)2(aq) + NaCl(aq) —> PbCl2(s) + NaNO3(aq)
We simply balance the equation by putting 2 in front of NaCl and 2 in front of NaNO3 as shown below:
Pb(NO3)2(aq) + 2NaCl(aq) —> PbCl2(s) + 2NaNO3(aq)
Answer:
-Before balancing the equation, you need to determine the index of the components in the substances correctly to balance
-Between two atoms in the molecule N2 forms a stable triple bond, so nitrogen gas is denoted N2.
-Nitrogen in compounds with sodium carries a charge of -3, and sodium has a charge of +1 in all compounds, so we get NaN3
Explanation:
answer from VNese, used GGtranslate
Answer:
The correct option is: E. No precipitate will form.
Explanation:
A solubility chart refers to the list of solubility of various ionic compounds. It shows the solubility of the various compounds in water at room temperature and 1 atm pressure.
Also, according to the solubility rules, the salts of chlorides, bromides and iodides are generally soluble and mostly all salts of sulfate are soluble.
Since, all the compounds formed in this double replacement reaction are soluble in water. Therefore, no precipitate will be formed.
ZnSO₄ (aq) + MgCl₂ (aq) → ZnCl₂ (aq) + MgSO₄ (aq)
