Sig Fig applies only to numbers that not zero, only except when the zero is after the the number.
For example:
0.0255 is three sigfigs
0.0050 is two sig figs
0.0005 is one sigfig
Answer: According to research
Lead when reacted with nitric acid forms lead (II) nitrate, nitrogen oxide and water
Explanation:
The 2 main components of the internal energy of a substance are:
The internal energy is a sum of kinetic and potential energy.
E_k (total)=E_k(translational) + E_k(rotational) + E _k(vibrational)
Internal energy is the microscopic energy contained in a substance, given by the random, disordered kinetic energy of the molecules. Further it includes the potential energy between those molecules, and the nuclear power contained in the atoms of those molecules.
The internal energy of a system is extensive property. it's a state property. The exchange is independent of the path followed. Change in internal energy of a cyclic process is 0.
Internal energy is affected by factors including pressure, volume, and temperature. All the variables on this listing are state functions.

What do you mean by this question?
Models are used to study atoms because we can't exactly study an atom with the naked eye, Using an enlarged model of an atom easier to study because we can pin point the different characteristics of the atom.
