In the past, there was more oxygen in the atmosphere due to higher levels of photosynthesis by plants and algae, which produced oxygen as a byproduct.
Oxygen is more electronegative than hydrogen in H2O. Oxygen has a stronger pull on electrons due to its higher electronegativity, causing it to attract the shared electrons more strongly in the water molecule.
There are a couple of ways of drying oxygen, the first it to cool it past its boiling point, then past its melting point. This gives you a solid block of oxygen, though the temperature has to be maintained to keep it solid. The second way is to pressurize it, with enough pressure oxygen will be compacted into a solid, though again the pressure has to be kept up or it will vaporise again.
No, oxygen is more reactive than nitrogen. Oxygen readily forms compounds with other elements, while nitrogen is relatively inert under most conditions.
Scientists use geological records such as rock formations, ice cores, and ocean sediments to measure oxygen isotope ratios. Changes in these ratios over time can provide insights into past oxygen levels. Additionally, the presence of certain fossils and chemical markers in rocks can also indicate past variations in atmospheric oxygen.
10.0 g of calcium has more atoms because calcium has a higher atomic mass than oxygen.
People have recycled and planted many trees and plants that will gives fresh air and more of it is here today.
Yes, oxygen levels were higher in the past, particularly during the Carboniferous period around 300 million years ago. During this time, oxygen levels were around 35% compared to the current levels of around 21%.
"More" is not a verb. It has no past tense.
oxygen can help you breathe and more.............
There can be no past tense for more, as it is an adjective, not a verb.
Plankton gives more oxygen to the atmosphere.
Oxygen (O) is more electronegative than Selenium (Se) because oxygen is higher up and to the right in the periodic table, which increases its ability to attract and hold onto electrons in a chemical bond.
there is more dissolved oxygen present in a stream because the movement and the bubbling of the air allows more oxygen to be ingested
First off, it doesn't burn more, it burns quicker. This is because It's reacting with the oxygen, and in a 100% oxygen environment there's simply more oxygen to react with (the air is 21% oxygen).
No. There is more oxygen in deeper water.
More oxygen, for the pumped blood circle through the body and the body consumes more oxygen and carries more oxygen than it carries carbon-dioxide.
because your body is using more oxygen so it needs to get more oxygen
