Carbon dioxide is made up of one carbon atom covalently bonded to two oxygen atoms. Although electrons are shared, they are not shared equally between the carbon and the oxygen atoms. The oxygen atom ...

Three students try out hands-on experiments with carbon dioxide in a science lab. With the help of Dr Peter Wothers at the University of Cambridge, they explore the properties of the air around us.

Soil carbon storage is a vital ecosystem service, resulting from interactions of ecological processes. Human activities affecting these processes can lead to carbon loss or improved storage.

In this activity, students use bromothymol blue (BTB) to test gas samples for carbon dioxide. They apply the technique in an experiment to investigate sources of carbon dioxide in their immediate ...

During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by ...

There is increasing evidence that the level of carbon dioxide in the Earth’s atmosphere is rising. There is also evidence that humans are responsible for this rise.

A team of scientists at NASA have confirmed how Mars' 'spider' formations are carved by carbon dioxide ... features in their ...

Carbon dioxide (CO 2) comes from both natural sources (including volcanoes, the breath of animals and plant decay) and human sources (primarily the burning of fossils fuels like coal, oil and natural ...

16 in the journal Nature. Both nitrogen and carbon dioxide can promote plant growth. In the grassland experiment, called BioCON, application of the two resources spurred growth that allowed a few ...

A person, company or country is carbon neutral if they balance the carbon dioxide they release into the atmosphere through their everyday activities with the amount they absorb or remove from the ...
