Answer:
Double displacement reaction
Explanation:
The chemical reaction is as follows :
NaCl + Pb(NO3)2 → PbCl + NaNO3.
Balanced equation:
Pb(NO3)2 + 2NaCl → PbCl2 + 2NaNO3
The reaction is a double displacement reaction . A double displacement reaction is a chemical reaction between compound where the cations and the anions of the 2 reactants exchange places to form a new product.
Double displacement reaction, the 2 reactants exchange ions to form new compounds. Double displacement reaction usually produce a solid precipitate. A good illustration of a double displacement reaction is
AB + CD → AD + CB.
From the reaction above the Sodium ion replace lead to from sodium nitrate while lead replace sodium to form the precipitate lead chloride. The anions(negatively charged ions) also exchange position.
Answer:
from 2-pentanone chloropentane pentene and pentane, the correct one is 2-pentanone
.
Answer:
<h3>The answer is 5.0 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 100 g
volume = 20 mL
So we have
We have the final answer as
<h3>5.0 g/mL</h3>
