Both ammonia and water exhibit hydrogen bonding. This is an intermolecular force that holds molecules together to increase their melting and boiling points. Water is a small molecule and really should be a gas at room temperature if you compare it to its nearest chemical relative, hydrogen sulfide. Water is not a gas, thank goodness, but a liquid due to hydrogen bonding.
Hydrogen bonding is the interaction of a slightly positively charged hydrogen nucleus with a neighboring slightly negatively charged small electronegative atom like nitrogen, oxygen or fluorine.
Ammonia, NH3 and water, H2O both have higher melting points due to hydrogen bonding. In chemistry the general rule is the bigger the molecule the higher its melting point.
Ammonia melts at -77oC whereas its bigger relative phosphorus trihydride, PH3, melts at a lower temperature of -133oC.
Similarly, water melts at 0oC but rotten egg gas, H2S, melts at -82oC.
Both ammonia and water owe their unusually high melting and boiling points to hydrogen bonding.
Another similarity between them is that both nitrogen and oxygen have electrons in their outer energy level that are not used to make a bond in water and ammonia. These are called lone pairs or non bonding pairs. Oxygen has two non bonding pairs and nitrogen has one non bonding pairs. This makes both water and ammonia attractive to hydrogen ions, H+(also called protons).

What is the standard test for ammonia gas?
Ammonia gas can be tested in these ways:1. It has a pungent smell2. It turns MOIST red litmus paper blue3. Test its alkalinity in water (pH ~ 11)4. It will extinguish a lighted splint5. It will easily dissolve in water
Is ammonia and methane the same?
No. Ammonia is NH3 gasMethane is CH4 gasthey are different in most ways other than the fact that they are both gases.
What are 3 ways you could determine in the lab if a solution had salt dissolved in it without tasting?
Boil the water, salt water boils at a different temp. than "plain" water; freeze it for the same reason; boil until all water is evaporated? any precipiate left?
How should ammonia be stored?
There are many ways to store. Normally we store it as a gas.
How is rocks extracted?
Rock salt is just big crystals of NaCl. It can be extracted in three ways. They can send people underground to chip it off the walls of a salt mine. They can drill holes in salt deposits and pump in water. As the salt breaks down, they pump in more water. After a year they pump the brine into shallow ponds and let the water evaporate. Or they can pump seawater into ponds and let it evaporate.
Which ways are city-states alike?
They had a defensively-walled city with a hill-fortress refuge, a tract of agricultural land to provide foodstuffs, a river for water, and usually a port and salt-water fishery.
In what ways can soil be alike?
In what ways can soil be alike
is salt necessary to treat water?
Salt is not necessary to treat water. There are many ways to treat water. Salt is not necessary because salt contains sodium. Sodium is good for treating water but is not necessary.
What is the simple way to remove blood from white cloths?
There are a few ways to remove blood from cloths. A few of these ways include soaking in cold water or using specialist liquids that are designed to remove blood. Other effective treatments include using baking soda,ammonia and salt.
What are some ways that salt water can be used to create fresh water for human use?
Salt water can be distilled, either by boiling it, or by evaporation in sunlight.
How are scientists turning salt water into fresh water?
they boil water then collect the steam in different ways
What two ways can salt be removed from salt water?
- by the evaporation of water crystallized sodium chloride is obtained - by distillation of water sodium chloride is obtained as a residual product
What do they do after salt is separated from water?
The salt crystals can be gathered and used in a variety of ways. Personally, I like salt on my fish and chips, here in the UK!
What are two ways of obtaining salt in the Sahara desert?
One way was to dig holes in the ground, pour salt water in it, and evaporating the water, leaving the salt behind. The second way was to mine for them from the salt mine in taghaza
In what ways are addition and multiplication alike?
Multiplication by an integer is the same as repeated addition.
What is the standard test for ammonia gas?

Do you no of any ways of extracting salt from water without using distilation?
---- yes, i do, if you evaporate the water you leve behind the salt. this is a simple yet effective way of the separation.
