Yes, you could consider air a gas, but air on earth is more commonly thought of as a collection of gases: oxygen, nitrogen, etc.
But on the other side, "gas is air" is not correct. When we talk about "air", we talk about the specific combination of gases that we breathe.
In other words, you would not say that a jar full of methane is air, but you could say that a jar full of air is a gas.
To get the same amount of oxygen to dissolve in plasma as carbon dioxide, you would need to increase the partial pressure of oxygen in the gas phase. This increase in pressure would drive more oxygen molecules to dissolve into the plasma to reach equilibrium with the gas phase. The solubility of a gas in a liquid is determined by Henry's Law, which states that the amount of gas dissolved is directly proportional to its partial pressure in the gas phase.
No, the diffusion rate of oxygen and bromine is not the same. Oxygen, being a smaller and lighter molecule, diffuses faster than bromine, which is larger and heavier. This is based on Graham's law of diffusion, which states that the rate of diffusion of a gas is inversely proportional to the square root of its molar mass.
No; the given statement is false. The natural atmosphere is largely a homogeneous mixture of oxygen and nitrogen gases, and it has very different chemical properties form any of the compounds formed from nitrogen and oxygen. Distinct such compounds with formulas N2O, NO, NO2, and N2O5 are known and are all chemically different from one another as well as from a homogeneous mixture of oxygen and nitrogen gases.
No, nitrous oxide and helium are not the same thing. Nitrous oxide, also known as laughing gas, is a dental sedative and anesthetic gas, while helium is a noble gas commonly used in balloons for buoyancy. They have different properties and uses.
Oxygen diffuses at the same rate as nitrogen. This is because both gases have similar molecular weights and sizes, allowing them to diffuse at a similar rate through a medium.
No, a gas is a state of matter. oxygen can be found in either liquid or gaseous states
No. They are different chemical elements as noted on the Chemical Chart. One is a metal and the other is a gas.
No, Hydrogen is an element and hydroxide is a compound made by oxygen and hydrogen (OH-)
No, nitrogen and oxygen are two different elements. Nitrogen is a diatomic gas with the chemical symbol N2, while oxygen is also a diatomic gas with the chemical symbol O2. They have different properties and functions in the atmosphere and living organisms.
Carbon and Oxygen are different elements.
[He]2s22p4
It has the same density as air.
There is no such thing as 02 gas. Perhaps you meant O2 gas, which is oxygen gas, consisting of molecules made of two oxygen atoms bonded together. O2 is essential for respiration in living organisms and combustion in fires.
Oxygen sensors are located at the same place on all cars cause they all do the same thing: analyze your exhaust gas. It will be on the exhaust pipe, between the engine and the catalytic converter. thats good but there are 3 of them
Hydrogen is a colorless gas that burns with oxygen. If substances will burn in air, those same substance will burn better in oxygen.
Because oxygen takes up much less space for the same amount of oxygen as a liquid rather than a gas.
No, oxygen is a chemical element, while oxidation is a chemical reaction that involves the loss of electrons by a substance. Oxygen is often involved in oxidation reactions, but they are not the same thing.
