How much oxygen nitrogen carbon dioxide is there in the air you breathe out?
Oxygen---------- 4-5 % Carbon dioxide---------- 20% Nitrogen--------- 75%
What gases do candles give off when burning?
Air is mostly Nitrogen, but that is not the "burning" part; Oxygen is probably what you are looking for, as that is the part that helps the candle burn, without there would be no fire. Or maybe you are looking for Carbon dioxide, that is what burning candles (which are mostly carbon) produces. What gas causes a candle to burn? Oxygen. It is the oxygen in the atmosphere that chemically combines with the wax of the candle to give Carbon dioxide gas and water vapor. What does candle need from air to burn? A candle requires oxygen (O2) to continue its combustion reaction and produce CO2 and H2O.
What gases do farts contain?
Farts typically contain gases such as nitrogen, oxygen, carbon dioxide, hydrogen, and methane. The specific composition can vary depending on factors like diet and individual health.
Oxygen and carbon dioxide are exchanged in lungs and through all cell membranes by?
Gas exchanges occur by simple diffusion through the respiratory membrane -- oxygen passing from the alveolar air into the capillary blood and carbon dioxide leaving the blood to enter the gas-filled aveoli.
Do plants emit carbon dioxide?
Plants do produce carbon dioxide, however, the amount they produce is generally a net NEGATIVE amount. Plants, like all carbon based life forms known to date produce carbon dioxide as they use energy for biological work. This is part of the normal functioning of cells that they require oxygen in order to do this work, during which they are consuming oxygen and sugars, bonding carbon with oxygen in the process creating carbon dioxide. If they did not do this, they could not grow, and could not repair damage. HOWEVER, plants also take in carbon dioxide and use it combined with light energy in photosynthesis. This process separates the carbon and oxygen molecules, and the carbon is utilized in the preparation of stored energy ("food"). The oxygen molecules are released into the atmosphere. In a healthy plant through the bulk of its life, the plant produces more oxygen and removes more carbon dioxide than it uses oxygen and produces carbon dioxide. Exact amounts will vary based on available light, plant species, water, atmospheric condition and overall health of the plant. In >general< the more green you see on the plant, the more of the plant involved in photosynthesis and the more oxygen it produces. however, this does not tell you how much oxygen it uses (and thus how much carbon dioxide it produces). but in general, plants (and other chlorophyll laden life forms) consume more carbon dioxide than they create.
What percentage of carbon di oxide in exhaled air is?
Exhaled air typically contains around 4-5% carbon dioxide. The majority of exhaled air is nitrogen, followed by oxygen and then carbon dioxide. This percentage can vary depending on factors such as metabolic rate and lung function.
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 percentage of each gas is in the air?
When you inhale air the concentration is abut 21% of oxygen but in your lungs some of it gets consumed and replaced by carbon dioxide the concentration of exhaled oxygen depends on your metabolism and oxygen consumption.
How much oxygen can one tree produce?
On average, a mature tree can produce enough oxygen for two people for a year. This can vary depending on the species and size of the tree. Trees absorb carbon dioxide and release oxygen through photosynthesis.
What is oxygen depth?
Oxygen depth refers to how deeply oxygen penetrates into a material or substance. This can vary depending on the density and composition of the material. Understanding oxygen depth is important in various scientific studies, such as in understanding the mechanisms of corrosion or oxidation in materials.
What are three things magma is made up of?
Magma is primarily composed of molten rock (silicate minerals), volatiles (such as water and carbon dioxide), and solid mineral crystals. The exact composition can vary based on factors like depth of origin, rock type, and geological conditions.
What do you breath in?
You breath in (inhale) all the gases in the atmosphere. viz. Nitrogen , Oxygen, Carbon Dioxide, Water, the inert(Noble) gases. However, only one gas is beneficial to animated life viz., oxygen. , which is absorbed into the animated organism. The animated organism then exhales carbon dioxide, together with all the other atmosphereic gases, formerly inhaled. In humans, carbon dioxide also regulates the breathing rate of approximately 40 breaths per minute. This can vary depending on the level of physical activity, e.g. sleeping, or running etc.,
