Answer:
A. = 143
B. = 8
C. =32
Explanation:
Number of neutron = mass number - atomic number
Answer:
The given molecules are:
a. C6H13NH2
b. CH3OH
c. CH4
d. C5H11OH
e. CO2
Explanation:
The hydrogen bond is a weak electrostatic force of attarction that exists between covalently bonded hydrogen (of -OH or -NH2 or HF) with a highly electronegative atom like N,O and F.
Hydrogen bonding is of two types:
Intermolecular hydrogen bond (exists between two molecules)
Intramolecular hydrogen bond(exists within a molecule).
For example intermolecular hydrogen bond in water is shown below:
Among the given options,
a. C6H13NH2 has -NH2 linkage which leads to hydrogen bond formation.
b. CH3OH has -OH bond and it leads to hydrogen bond fomation.
d. C5H11OH has also -OH bond and it leads to hydrogen bond fomation.
Reamining molecules, CH4 and CO2 do not form hydrogen bond.
Hence, answer is:
options a,b,d.
Pressure belts affects the climate of an area in such a way that Low pressure belt produces rain and storms and weather conditions that are unstable.
<u>Explanation:</u>
It is the movement of air that creates difference in the pressure and this is called as Pressure gradients. The patterns of pressure that exists over a period of time in an area is called as pressure belt. The pressure belt or wind belt highly depends on the temperature of an area.
Pressure belts can affect the climatic conditions of an area greatly. Air when rises it can create lower pressure and air when shrinks it can result in higher pressure. When the pressure is low then it can create a weather condition in an area which is unstable. It can create rain or storm.

Answer:
Who contributed the most to the atomic theory?
After Democritus' discovery, new evidence would be found that would eventually lead to the modern atomic theory. John Dalton, J.J. Thompson, Ernest Rutherford, Niels Bohr, James Chadwick and Ernest Schrodinger each contributed greatly to the modern atomic theory by finding the actual evidence.
