Some reactions are possible:
2 CO2 = 2 CO + O2
CO2 + 2 Mg = 2MgO + C
An element.
Carbon is an element and the definition of an element is that it cannot be broken down into any other element using chemical means. through fusion and fission it could be broken down or built up into oxygen or nitrogen or any number of other elements. But not without unearthly large amounts of energy (usually from a supercollider)
With the break up of the supercontinenent, Rodinia, there were of course many smaller continents which led to more rainfall and consequently less carbon dioxide in the atmosphere (since rain "washes" the carbon dioxide out of the atmosphere). As a result of less carbon dioxide in the atmosphere, temperatures dropped and ice began to form in polar regions.
an electron
Heating calcium carbonate (CaCO3) produces an endothermic reaction because energy is absorbed in the form of heat to break the bonds between the calcium, carbon, and oxygen atoms in the compound. This results in the decomposition of calcium carbonate into calcium oxide (CaO) and carbon dioxide (CO2).
It depends what has broken, some problems are easily repaired. In most cases it is simpler and more cost effective to buy a new one.
federal government is broke. More highway transportation vehicles combust fossil-fuels than do carry payloads of cryogenic liquified carbon dioxide gas. Can you say hypocrates?
no. wanna know why? a pure substance is made up of only one type of atom. atoms can't be broken down (divided) definition of an atom: that which cannot be divided. there ya go! ur welcome :) -shamansh
Your mucus plug might of broke, I would talk to your ob/gyn
There is little free oxygen on Venus, although almost all of the water there apparently broke down into hydrogen and oxygen. The majority of the planetary oxygen is bound as carbon dioxide and sulfur dioxide in the atmosphere, and as oxides on the surface.There is apparently no plant life on Venus, and plants are what supply the atmospheric oxygen on Earth.
I know almost had the uber lights that had a core of carbon fiber with wood around it. It was like a mini carbon fiber board inside a wooden board. They are said to be indestructible (mine broke). There are also the fiberprime from foundation and the P2 Technology used by NHS... AWS makes one as well, or at least did.
Well, honey, "line broke" means the monkey's tobacco-chewing escapade came to a screeching halt when the streetcar line snapped. In simpler terms, it means the monkey's joyride was cut short because the damn line broke. So, next time you see a monkey chewing tobacco on a streetcar, make sure that line is sturdy!
