From the solubility rules, both reactions 1 and 2 lead to precipitates.
<h3>What is a precipitate?</h3>
The term precipitate refers to the solid that separates out of the reaction mixture . We know that the solubility of a substance in water is predicated on the solubility rules.
1) The reaction here is;
Fe(NO3)3(aq) + 3NaOH(aq) ------> Fe(OH)3(s) + 3NaNO3(aq) - The precipitate is Fe(OH)3 because only the hydroxides of group 1 elements are soluble in water.
2) The reaction is;
Pb(NO3)2(aq) + 2KI(aq) ----->PbI2(s) + 2NaNO3(aq) - The precipitate is PbI2 because most iodides are soluble except the iodides of Ag+, Hg+2, and Pb+2
Complete Ionic equation;
Pb^2+(aq) + 2NO3^-(aq) + 2K^+(aq) + 2I^-(aq) ------> PbI2(s) + 2NO3^-(aq) + 2K^+(aq)
Net ionic equation;
Pb^2+(aq) + 2I^-(aq) ------> PbI2(s)

##SPJ1
The average force on the car=3857 N
Explanation:
mass of car= 1000 kg
initial velocity= Vi=0
Final velocity= Vf=27 m/s
time= t= 7 s
using the kinematic equation,
Vf= Vi + at
27=0+a (7)
a=3.857 m/s²
Now the force is given by F= m a
F=1000 (3.857)
F=3857 N
Answer:
They move farther apart
Explanation:
When objects heat up they expand for example heating up a balloon makes it expand
