Is the world running out of oxygen?
Trees create oxygen and many trees are here and still being plated dont worry about it we will run out of oxygen in aprox. 952,012,015,486,255,225,477,763,254,214 and by that time the world will probably end so we will never run out of oxygen.
A hyperbaric chamber has a volume of 1490 L . how many kilograms of O2 gas are needed to give an oxygen pressure of 3.50 ATM at 29 C?
6,73 kg oxygen
How much oxygen does an acre of corn produce?
According to the USDA, one acre of corn removes about 8 tons of carbon dioxide from the air in a growing season. At 180 bushels per acre, corn produces enough oxygen to supply a year's needs for 131 people.
How or where does a tree get oxygen to give us?
A tree absorbs carbon dioxide from the air, and, with the input of energy from sunlight, oxidizes many of the oxygen atoms of the absorbed carbon dioxide to elemental oxygen, which is released into the atmosphere. The carbon and some of the oxygen atoms from the absorbed carbon dioxide are incorporated into the structure of the tree as the tree grows.
Why is a compound different from an element?
a compound is many elements mashed together into one. water is H2O and is a compound. H2 for 2 hydrogen molecules, and O for 1 oxygen molecule. Oxygen is an element. When you give 1 oxygen molecule 2 hydrogen molecules it becomes a compound.
Do you need trees to live?
Technically, I believe we do need trees to live. As we give off carbon dioxide, the trees and plants give off oxygen. Without them, we would die. Trees also have many uses.
How would uncontrolled cutting of pine trees impact the environment?
If too many pine trees are cut down in forest ecosystems, there will be no place for animals that live in the forest to live. We also need the oxygen trees give off, in order to breathe.
How many people can an average size tree keep alive with the oxygen it produces?
it would take about 27 trees to produce enough oxygen for one person.
What does the rubber tree give us?
It gives us rubber(coming from the name) and oxygen as well as many other trees
History of oxygen?
Oxygen has came from trees many years ago.
How many trees can produce oxygen?
Every tree produces oxygen...
What does chopping down trees do for us?
it gives us a resource of paper, desks for school, buildings, fixing things and a bunch of other stuff. it also can kill us if we chop to many trees down because trees give off oxygen and we need oxygen to live. we breath out carbon dioxide and trees take that in for oxygen. if cutting down trees bothers you, you should do something about it and stick up for the trees like i have and make a change.
Why are does the US have so many trees?
The us has so many trees because we use their oxygen
Why do you need so many trees?
we need trees beacuse it gives us oxygen and without oxygen we wouldnt be alive
If there were no trees would you have oxygen?
Yes, there would still be free oxygen in the air if there were no trees. There are many plants that are not trees and that release oxygen. In fact, the Earth's atmosphere was rich in oxygen due to the metabolism of plants in the oceans ages before the first trees appeared on the land.
How many people can use oxygen produced by tree?
It requires 22 trees to produce the amount of oxygen consumed by one person. (An acre of trees produces enough oxygen for 18 people). This data comes from the Northwest Territories Forest Management site:http://forestmanagement.enr.gov.nt.ca/forest_education/amazing_tree_facts.htmHow_many_people_can_use_oxygen_produced_by_tree
Why trees are importance?
Trees are an important component of the natural landscape because of their prevention of erosion and the provision of a weather-sheltered ecosystem in and under their foliage.Trees also play an important role in producing oxygen and reducing carbon dioxide in the atmosphere, as well as moderating ground temperatures. They are also elements in landscaping and agriculture, both for their aesthetic appeal and their orchard crops (such as apples). Wood from trees is a building material, as well as a primary energy source in many developing countries. Trees also play a role in many of the world's mythologies (see trees in mythology).Animals such as squirrels make homes in trees. In the summer when it's hot, they give us shade.They give oxygen. People destroy them for wood and paper.
