This is interesting and very true. Humans (based on evolution) evolved from a single cell in large bodies of water. Over time these cells formed with others and adapts to their environment. Through a long process, these creatures left the water for land, and blah blah blah.
What if most of the ocean was land with a lot of streams and small lakes? How would life be different?
Large bodies of water like the ocean gave early life the room to adapt and grow in size and quantity.
The reason water expands when frozen is due to hydrogen bonds. Due to dipoles in the water you get hydrogen and oxygen aligning up which also why snowflakes are the shape they are. At work atm but will post a better explanation when i get home for those who are interested.
Isn't it simple why water molecules get bigger when freeze...... when it gets cold - they all put on very small hats, scarves, gloves and big wooly jumpers ---- hence they look bigger!!
Elements are not trying to "be neon" when the form ionic or covalent bonds. It's called a stable octet.
Well I was considering if this was worth discussing it not But then I read your response If you are going to call everyone who disagrees with you stupid or just tell them to shut up. Then why open a discussion thread. You are stating your belief about a topic be it right or wrong and not a discussion about science. Btw. The stupid ones are those who would find accurate information based on simple matters the most useful. Those who already know how electrons, particles and neutrons etc work don't need you telling them how to suck an egg.
Great to see this being thought through, but while water's properties are absolutely perfect for life on earth, they are not totally unique. There are many mistakes in what has been said here, but talking about it is a great way to learn. I teach college chemistry (PhD). Feel free to pm me if you have questions.
These days, many people know the importance of staying hydrated, but easy access to clean water isn't always available and carrying around heavy water bottles all the time can be tiring. Well, I have the solution to your problem - dehydrated water! Dehydrated water takes up a fraction of the space of regular water and is so light you will feel like you are carrying nothing at all! Some people buy expensive commercial brands of dehydrated water But there's really no need because it's so easy to make anyone can do it and it only takes minutes. So, read on and I will tell you how to make your own dehydrated water and how to rehydrate it when you are ready to drink. You will need: A pot Clean drinking water Stove Storage container (an empty water bottle works well) Step 1: Dehydrate the water Fill your pot with clean drinking water. Tap water works fine or you can use bottled water. Bring the water to a boil on the stove. Continue boiling until all the liquid is evaporated. What you have left is dehydrated water. Step 2: Store the dehydrated water: Now simply pour the contents into the storage container of your choice. Dehydrated water does not take up much space so it can be stored in tiny containers but I find it best to put it straight into a water bottle. That way you do not have to carry an extra container with you and can use the water bottle to hold the re-hydrated water. The next step will explain the rehydrating process. Step 3: Rehydrate the water Rehydrating your dehydrated water is very simple. All you have to do is add clean drinking water to the container holding the dehydrated water. It should rehydrate instantly. If you wish you can give the container a shake to be sure none gets stuck to the bottom, but this is not really necessary. Now it is ready to drink and guess what? It will probably taste better because you made it yourself! That's all there is to it! Enjoy! (Note: Stolen from the internet)
Structural formula for water would be H-O-H, each line suggests 2 electrons being shared. All atoms/molecules want to obtain a duplet or an octet configuration, that is to say, either 2 or 8 electrons on it's valence shell(outermost shell). I think water is more of a covalent compound(bonds formed are between non-metal and non-metal), since it shares electrons. However, if you say water is an ionic compound, I think you are referring to its oxidation state, as oxygen has a general oxidation state of -2 and all molecules are of a 0 oxidation state. Calculate the oxidation state of hydrogen. It will be 1. The -2 and 1 are not to be confused with the charges, as only ionic compounds possesses these charges. Well this is my input, kindly correct and add on if possible.
Kinetic energy relates to the object as a whole While technically it is kinetic energy just in each individual molecule its more commonly known as thermal energy
I was talking about people who reply to say the subject is stupid. If they don't have anything discuss ice to say, and they're just going to be rude and bag on a decent thread just to bag on it, don't.
