How is water formed chemically?
When molecular hydrogen (H2) and oxygen (O2) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide.
These two processes are represented by the two chemical equations shown at right..
How do humans destroy rivers?
Sulfur dioxide and nitrous oxide emitted from factories and power stations enter river systems through acid rain. Sewage and effluent are discharged into rivers in some areas. Pollution can lower the pH of the water, affecting all organisms from algae to vertebrates. Biodiversity decreases with decreasing pH.
What country has the cleanest water in the world?
ChileDid you know that the very cleanest water in the world is located in Puerto Williams, Chile? That was recently discovered by scientists at the universities of Texas and Chile. They have collaborated on research into the cleanliness of water resources in the world.
Can water be created or destroyed?
When water is broken up to form other molecules (which is a constant occurence in biology), the molecules eventually break down, combust or otherwise react and eventually end up as water again. In short, water is created as often as it’s destroyed, and that’s unlikely to ever change.
How old is the water?
3.8 billion yearsThere is also geological evidence that helps constrain the time frame for liquid water existing on Earth. A sample of pillow basalt (a type of rock formed during an underwater eruption) was recovered from the Isua Greenstone Belt and provides evidence that water existed on Earth 3.8 billion years ago.
Can scientists make water?
Summary: Scientists have discovered a new way to make water. … A water molecule (formally known as dihydrogen monoxide) is composed of two hydrogen atoms and one oxygen atom. But you can’t simply take two hydrogen atoms and stick them onto an oxygen atom.
How much water will there be in 2050?
If monthly, rather than annual, variability is considered, 3.6 billion people worldwide, slightly less than 50% of the global population, presently live in potential water-scarce areas at least 1 month per year. This number will increase from 33 to 58% to 4.8 to 5.7 billion by 2050.
Is water ever created?
Our planet may be blue from the inside out. Earth’s huge store of water might have originated via chemical reactions in the mantle, rather than arriving from space through collisions with ice-rich comets.
Is it OK to drink day old water?
The growth of bacteria is even high when you store the water in a warm area. You should avoid drinking water left open for a very long time. The water left overnight or for a long period of time in an open glass or container is home to numerous bacterias and is not safe for drinking.
What 4 elements are in all living things?
Most common elements in living things are carbon, hydrogen, nitrogen, and oxygen. These four elements constitute about 95% of your body weight.
Does the earth make new water?
When Earth formed, the hydrogen surrounding the growing planet was captured in its rocks and minerals. When hydrogen-rich and oxygen-rich minerals melt because of the mantle’s heat, the resulting water can spew from the planet’s crust.
Why we Cannot run out of water?
Luckily, good old planet Earth is very good at holding on to water, meaning the amount of freshwater which is available to us stays relatively constant over time. When water evaporates it doesn’t escape into space because our atmosphere is pretty cold. The water freezes into solid crystals and falls back to Earth.
Can we destroy water?
Originally Answered: Can water be destroyed? Law of conservation of matter- matter can neither be created nor destroyed. … You can change water into another state like solid or gas or even plasma. If you heat it to very high temperatures, you can even separate it into hydrogen and oxygen.
How much water is wasted every day?
It’s Time to Test Your WaterSense! The average person unknowingly wastes up to 30 gallons of water every day. And since usable water is a limited resource, 36 states could be facing water shortage problems by 2013.
Can we ever run out of oxygen?
Most of the breathable oxygen in Earth’s atmosphere is supplied by plant life in a process called photosynthesis . We’ll run out of it if we cut down too much of the world’s forests and kill too much plant life in the oceans. … As long as we sustain Earth’s plant life in sufficient quantity, we won’t run out of oxygen.
Does water have DNA?
DNA that helps make germs resistant to medicines may increasingly be appearing as a pollutant in the water. This DNA was found “even in treated drinking water,” researcher Amy Pruden, an environmental engineer at Colorado State University in Fort Collins, told LiveScience.
Why is water called water?
The word water comes from Old English wæter, from Proto-Germanic *watar (source also of Old Saxon watar, Old Frisian wetir, Dutch water, Old High German wazzar, German Wasser, vatn, Gothic 𐍅𐌰𐍄𐍉 (wato), from Proto-Indo-European *wod-or, suffixed form of root *wed- (“water”; “wet”).
Why is the water wet?
“Water is wet because when something is wet, it has water on it and on a molecular level, water molecules are bonded on top of each other, therefore water is wet.” An extension to the previous argument that a couple of students brought up was that one water molecule alone is not wet, but when water molecules touch each …
