How will you show the presence of carbon dioxide in air ?
Answers
Explanation:
the weight of an object is the force acting on the object due to gravity. Some standard textbooks define weight as a vector quantity, the gravitational force acting on the object. Others define weight as a scalar quantity, the magnitude of the gravitational force.
Answer:
there are some ways to find it out
Explanation:
A standard test for the presence of carbon dioxide is its reaction with limewater (a saturated water solution of calcium hydroxide) to form a milky-white precipitate of calcium hydroxide.
Carbon dioxide occurs in nature both free and in combination (e.g., in carbonates). It is part of the atmosphere, making up about 1% of the volume of dry air. Because it is a product of combustion of carbonaceous fuels (e.g., coal, coke, fuel oil, gasoline, and cooking gas), there is usually more of it in city air than in country air. For the last 800,000 years the carbon dioxide in the atmosphere has oscillated over tens of thousands of years between 180 to 280 parts per million (ppm), but since the Industrial Revolution it has steadily increased above 280 ppm in a relatively brief time, reaching 400 ppm in 2013. This extra carbon dioxide fuels the greenhouse effect, warming the atmosphere and further disrupting the natural carbon dioxide cycle (see global warming), and controlling the carbon dioxide produced by human activities is key to limiting global warming and the disruptive effects of climate change.
