What else can I help you with?
Can you live in an atmosphere that consists of carbon dioxide?
No, you cannot live in an atmosphere that consists solely of carbon dioxide. Humans and most other animals require oxygen for respiration, and a high concentration of carbon dioxide can be toxic, leading to suffocation. While some organisms, like certain bacteria and plants, can thrive in carbon dioxide-rich environments, they have evolved mechanisms to utilize it for energy or survival.
What releases oxygen and glucose?
Plants and other organisms that rely solely on photosynthesis.
Carbon dioxide gas is heavier than both nitrogen and oxygen. Why does it not form the lower layer in the atmosphere?
The distribution of gases in the atmosphere is mainly governed by their molecular weight and the temperature gradient. While carbon dioxide is heavier than nitrogen and oxygen, it is well mixed throughout the atmosphere due to the effects of atmospheric circulation and mixing processes. This prevents it from forming a distinct lower layer based solely on its density.
Do human cells create carbon dioxide at low oxygen conditions?
No there are situations where do excrete carbon dioxide. Conditions of low oxygen can force cells to rely solely upon anaerobic metabolism. The buildup in lactic acid during exercise is a consequence of this.
What colour chemical be if carbon dioxide is not present?
If carbon dioxide is not present, the chemical composition of substances will vary widely, so there isn't a specific color associated with the absence of CO2. However, many chemicals can appear colorless, such as water or oxygen. The color of a chemical depends on its molecular structure and the presence of specific elements, not solely on the absence of carbon dioxide.
What was wrong about Van helmonts conclusion that when plants grow their increase mass on some water?
Van Helmont concluded that the mass gained by a plant during growth came solely from water, based on his experiment with a willow tree. However, he overlooked the role of soil nutrients and carbon dioxide from the air in the growth process. Modern understanding reveals that plants also absorb carbon from CO2 during photosynthesis, contributing significantly to their biomass. Thus, attributing the increase in mass solely to water was an incomplete assessment of plant growth.
What two chemicals are based on carbon content?
Two common chemicals based on carbon content are hydrocarbons and carbon dioxide. Hydrocarbons, which consist solely of hydrogen and carbon atoms, are found in fuels like gasoline and natural gas. Carbon dioxide, a compound of carbon and oxygen, is a critical greenhouse gas produced by respiration and combustion processes. Both play significant roles in environmental and industrial contexts.
What could happen to the plants if there are no animals?
It depends what you mean by animals. If you're are talking solely about vertebrates (having a backbone like humans, mammals, fish and others) then the answer is not much. Bacteria produce a lot of carbon dioxide. Plus Carbon Dioxide is released naturally through volcanic activity. Plants would still have plenty of CO2 to continue breathing. On the other hand, if all forms of life that used oxygen to breathe were to suddenly vanish, they is a very good chance that most plants would cease to function as they wouldn't have enough CO2 to breathe.
Are seashells made out of carbon?
Seashells are primarily made of calcium carbonate, which is a compound derived from calcium and carbon dioxide. Carbon is a component of the calcium carbonate molecules that make up the structure of seashells, but seashells are not made solely of carbon.
When do plants respire?
Plants respire all the time, but it can be seen better at night. This is because photosynthesis has the opposite chemical formula, and since there is light, more oxygen returned out, then carbon dioxide is taken in.
Why does pop go flat at room temperature more easily than in the refrigerator?
It doesn't lose its fizz in any kind of temperature, because when you shake it up, there is already a certain amount of carbon dioxide that exists within the confines of the pop, and the fizz is the release of the carbon dioxide when being trapped in bubbles. It solely depends upon how much carbon dioxide exists within the pop.
What volume of carbon monoxide at STP is needed to produce 541 mL of carbon dioxide?
Using the ideal gas law - the volume of a gas is independent of it composition and is determined solely by the equation PV=nRT. As one mole of CO would produce one mole of CO2 it would take 541 mL of CO to produce 541 mL of CO2.
