Answer: 
Explanation:
Lattice energy : It is defined energy released when ions combine together in a gaseous phase to form a compound. it is energy possessed by the crystal lattice of a compound. Denoted by symbol 
.
, energy is absorbed while forming of the lattice
, energy is release while forming of the lattice
One mole of sodium ion when combines with one mole chloride ion release 786 kJ of energy.
Answer:
Option C.
The Bohr effect describes the effect of pH on the affinity of hemoglobin for oxygen.
Explanation:
The hemoglobin is the oxygen carrying part of the blood. However, According to Christian Bohr, the binding affinity for oxygen by the hemoglobin in the blood is greatly affected by the acidity and content of carbon dioxide in the blood. As a matter of fact, they are inversely related. The more acidic the blood is, or the lower the pH of the blood, the lower the amount of oxygen that can become bonded with the hemoglobin in the blood.
The statement a) it orbits around the nucleus of an atom. does not describe a proton.
- Protons is known as nucleon and Is found in the nucleus. It doesn't revolve around nucleus of atom.In circular orbits, electrons move around the nucleus.
- In his well-known gold foil experiment from 1911, Ernest Rutherford made the discovery of the atom's nucleus.
- He came to the conclusion that the majority of an atom's volume was empty and that all of the positively charged particles in it were concentrated in a single core.
- The mass of a proton is around 1835 times that of an electron.
- The atomic number is the quantity of protons in an element's nucleus.
- The mass of a proton is 1.6726219 × 10^-27 kilograms.
Proton is embedded inside the nucleus of atom along with neutron and electron revolve around the nucleus in fixed orbit.

Mass Spectrometer - is an analytical technique that ionizes chemical species and sorts the ions based on their mass-to-charge ratio. It measures the masses within a sample.
Answer:
Sun gives heat and light to earth. Earth orbits sun in 365.242 days. THis orbital motion makes seasons along with axial tilt of Earth.. Suns heat makes clouds making rains.so most places on earth gets water and plants survive.
