The matter surrounding a comet’s core is vaporized and forms a very bright halo of gases and an enormous cloud of hydrogen envelopes the head of the comet.
A comet is a tiny, icy body in space that may be identified by its stunning tail when viewed from Earth. Only when a comet is getting close to sun, the ice and particles that make up the comet's core heat up and start to dissolve.
Therefore,the material encircling the centre vaporises and creates a very bright halo of gases and a sizable cloud of hydrogen. Most comets follow a solar orbit. The atmosphere of gas created by the ice melting is what causes the coma.

Answer:
Answered below
Explanation:
Water is essential for the normal functioning of the organ systems in the body. Dehydration occurs when the water we take in is less than the water we lose. Water is lost fr the body through sweating, breathing, urination and defecation. Disease conditions like diarrhea and vomiting also cause loss of water.
When the body senses dehydration, there is a thirst signal to tell us to drink more water. The body then proceeds to the water leaving through the kidneys thereby conserving water in the body. This explains the concentrated and colored urine during dehydration.
Circulation to the skin and muscles is decreased, leading to dry and clammy skin, muscle cramps, dry eyes etc
The body increases the heart rate and pumps blood to the vital organs such as the brain, lungs, heart and intestines.
For Chlorine, CI
The protons and electrons will be the same except Protons will be + positive and electrons will be - negative so your answers are 17 and -17
neutrons is 18
atomic number 17
Atomic mass: 35.453
For sodium, Na
The protons and electrons will be the same except Protons will be + positive and electrons will be - negative your answers are 11 and -11
neutrons : 12
atomic number: 11
Atomic mass: 22.9897
hope this helps good luck
