Chemical equation:
Pb(NO3)2(aq) + 2NH4I(aq) -->PbI2(s) + 2NH4NO3(aq)
Precipitate:
PbI2 (because it's a yellow insoluble solid)
Complete Ionic Equation:
Pb(aq) + 2NO3(aq) + 2NH4(aq) + I2(aq) --> Pb(s) + I2(s) + 2NH4(aq) + 2NO3(aq)
Net ionic equation:
Pb(aq) + I2(aq) --> Pb(s) + I2(s)
Let me know if there are any errors. Goodluck :)
Answer:
No.2, No.3 and No.4 answers are same. Give the options properly.
Why is it that nitrogen is often a limiting plant nutrient, despite the fact that the atmosphere is 80% nitrogen gas because plant can not fix nitrogen.
What is nitrogen fixation?
Nitrogen fixation is a chemical process that converts molecular nitrogen (N2) in the air, which has a strong triple covalent bond, into ammonia (NH3) or related nitrogenous chemicals.
With the exception of a few microbes, atmospheric nitrogen is molecular dinitrogen, a largely nonreactive chemical. Diazotrophy, or biological nitrogen fixation, is an important microbially driven process that transforms dinitrogen (N2) gas to ammonia (NH3) via the nitrogenase protein complex.

Carbohydrates called starches
Answer:
7.56 atm
Explanation:
Boyle's law states that the pressure and volume of a gas are proportional to each other
The formular for Boyle's law is
P1V1=P2V2
According to the question above, the values given are
P1=1.50 atm
P2= ?
V1=12.60 litres
V2= 2.50 litres
Let us make P2 the subject of formular
P2= P1V1/V2
P2= 1.50×12.60/2.50
P2= 18.9/2.50
P2= 7.56 atm
Hence when the volume of a gas is 2.50 litres then it's pressure is 7.56 atm
