Answer: Neurone or Nerve cell
Explanation:
The bonds in a substance breaks down in a phase change from liquid to gas and the molecules move independently of each other.
It is conventional to describe chemical bonds with the aid of elastic materials such as a rubber band. This analogy can only apply to covalent bonds between atoms in which the bonds between atoms are stretched.
However, in discussing the bonds in a substance when considering phase changes, this analogy breaks down because for a phase change from liquid to gas, the bonds break completely and particles can move independently of each other.

Answer:chemistry is a subject that deals with composition of substances and of the changes which they undergo in consequences of alteration in the constitution of molecules which depend upon variation of the number, kind or mode of arrangement of the constituent atom while biology deals with characteristic life processes and phenomena of living organisms
Explanation
1.
n = m/2.016 g/mol = V/22.4 l
V = 22.4 l
Hence,
m = 2.016 g ≈ 2.02 g
B.) 2.02 g
2.
Balancing the equation, we get,
Mg + 2HCl → MgCl2 + H2
PV = nRT
V = nRT/P
V = 1.5 mol × 8.314 atm/(mol.K) × 298 K/(0.96 atm)
V = 3871.206
V ≈ 38.2 l
