Carbon dioxide is also known as CO2. It is composed of two oxygen atoms bonded to a single carbon atom. At standard temperatures, CO2 is in a gas form. Some people make CO2 for making their vegetable gardens more productive. Plants use CO2 in the photosynthesis process. You can even injec...
These tips will help you turn your daily water intake from chore to delight By Charlie Robertson / 03 Jul 2022 Staying hydrated isn’t just about keeping thirst at bay – water is essential for the human body to function, transporting nutrients and oxygen around the body....
At the ocean's surface, a small — proportion of gases like oxygen and carbon dioxide dissolve into the water — dissolved oxygen, for example, allows sea creatures to breathe.在海水表面，有很小一部分的气体，比如氧气和二氧化碳，溶解在海水中 (举个例子，氧的溶解可以让海洋生物呼吸)。And when t...
These devices make oxygen from water by a process called electrolysis, during which an electric current passes through water from one positively-charged electrode called an anode to another negatively-charged electrode called a cathode. There's a small concentration of salt in the water to conduct ...
atomic weight of Carbon is 12u, and the atomic weight of Oxygen is 16u. The weight of CO2in trees is determined by the ratio of CO2to C is 44/12 = 3.67. Therefore, to determine the weight of carbon dioxide sequestered in the tree, multiply the weight of carbon in the tree by ...
Female plants make seeds Cannabis dies for winter Repeat – Everything starts over again for the next generation Why is this important? Cannabis plants go from seed to death in just one year, and they have a certain order for their life stages. This is very important for you to understand...
The ISS also has systems that make breathable oxygen from recycled water. Using electrolysis, some of these devices split water into hydrogen and oxygen gas. Then, the former is combined with an undesirable compound: carbon dioxide (CO2). Humans naturally exhale this colorless gas, but breathing...

The main reason it seems to work: You don't get lactic acid. Lactic acid causes the miserable feeling of muscle weakness; it comes with the territory of doing anaerobic (oxygen-depleted) exercise. But since the extra CO2 from your controlled breathing releases more oxygen, you're not really...
