In the presence of sunlight, trees take in carbon dioxideand water and exhale oxygen. This is called photosynthesis and is why trees are important to us humans.
The trees also respire. Respiration is the process by which any cell combines sugar and/or starches with oxygen and gives off carbon dioxide and water with a release of energy. This takes place in all cells, including plants - with or without the presence of sunlight. The effect of photosynthesis and respiration together is to make trees net absorbers of carbon dioxide. In one year a mature tree will use approximately 22 kg more CO2 than it gives off through respiration, and will give off approximately 16 kg more O2 than it uses in respiration. (Related to this subject is NASA's research that average human oxygen consumption is approximately 0.84 kg/day or 307 kg/year. At this rate it requires nearly 20 mature trees to support the breathing of each human.)

A science teacher added the reactive metal potassium to water. The metal formed a ball shapeon the surface of the water and the gas given off burned with a pop. Name the gas given off.?
hydrogen
What gas is given off when ethanoic acid reacts with magnesium?
h2
What the purpose of the gas Hydrogen?
Hydrogen is the lightess, but most common element in the galaxy. It can be used to make balloons rise, be burned to give off heat, or burned to give engine thrust.
What gas is given off when calcium is mixed with water?
The calcium metal will react with the water to form calcium oxide and give off Hydrogen gas.
When calcium carbonate is heated what gas is given off?
carbon dioxide is produced when it is heated
What gas is given off when coal burns?
Carbon dioxide is the gas given off. Oil also gives off the same gas when burned.
What gas is given off when carbon based fuels are burned in air?
Carbon dioxide (CO2).
A science teacher added the reactive metal potassium to water. The metal formed a ball shapeon the surface of the water and the gas given off burned with a pop. Name the gas given off.?
hydrogen
What device analyzes the light given off when an element is burned?
A spectrometer analyzes the light given off when an element is burned.
When oil and gas are burned what kind of gas does it give off?
If combusted in air(oxygen), then the gases given off is carbon dioxide, and water vapour.
What is given off when biomass is burned?
CO2 primarily
What gas released when fossil fuels are burned is also given off when biomass is burned?
That would be carbon dioxide (CO2).The amount of carbon compounds (like CO2) that the creation or use of a given fuel source releases into the environment is known as its carbon footprint.
What gas would be given off if graphite hydrochloric were mixed?
None, no gas is given off.
When you burn Super Glue what toxic gas is given off?
Cyanoacrylate gas is given off.
What Problems were caused by the Mount Helens eruption?
Hundreds of thousands of trees were burned down, people died from the toxic gas given off, and cities were destroyed.
Is feces power sustainable?
technically yes as the gas given off buy most faeces human and animal is methane. Methane can be burned to create heat.
What gas is given off when metal is burned?
It depends upon the subsance being burned. Normally, the substance would end being some sort of oxide (O2 molecule being attached to the base molecule of what is being burned).
