Is NO2 More Dense Than CO2?

The popularity of No2 has led to comparisons with numerous other products. No2 is often used in reference to MRI's No2 product, the supplement formula for bodybuilding. NO2 supplement reviews compared to Co2 the discussion is around nitrogen dioxide, scientifically named NO2 (with the 2 subscripted), or nitric oxide, which is abbreviated NO.

The Difference Between No2 and NO2

First consider what NO2 (nitrogen dioxide) is and how it operates. Nitrogen dioxide is a chemical compound which is one of several different nitrogen oxides. It is a gas that is reddish-brown in color and has an odor that is pungent and sharp. NO2 is one of the most common forms of air pollutants and can be poisonous if inhaling. Symptoms of poisoning appear several hours after one has inhaled the gas. Even a low inhalation of nitrogen dioxide can possibly be fatal. Very low concentrations of the gas can anesthetize the nose. NO2 is powerful and can be deadly! The density of nitrogen dioxide is 1443 kg/m3, in liquid 3.4 kg/m3 or at gas at 294.25 K. Given the danger of this gas, it's very unlikely you're looking for nitrogen dioxide in any form outside of testing and research!

Extended Release Generator

On the opposite end of the spectrum there is nitric oxide, which is not actually identified as No2, but NO. Its association with No2 comes from the fact that MRI (Medical Research Institute) released their extended release nitric oxide generator with the label No2, representing the ingredient NO. This just means that it has the ability to prolong the natural effects of you own body's nitric oxide production.

What is nitric oxide and what effect does it have on the body? NO has many positive effects unlike NO2. Nitric oxide, also known as nitrogen monoxide, is a chemical compound in the form of a gas that acts as a signaling molecule. So it tells your body what to do and how to react in a given situation.

Comparing Densities

Interestingly, though nitric oxide is naturally produced in human beings, it is also used as an intermediate in the chemical industry and produced by automobile engines and power plants in the form of a toxic air pollutant (like nitrogen dioxide). The nitric oxide molecule is called a free radical and has high reactivity. Chemically speaking, it reacts with ozone in the air to create nitrogen dioxide, the poisonous gas. The density of nitric oxide is 1.3 x 103 kg m?3 in liquid form and 1.34 g dm?3 as a vapor.

There is also nitrous oxide to consider, though its abbreviation is slightly different as N2O. This chemical compound gas (nicknamed laughing gas) and is colorless and non-flammable. The odor of N2O is actually sweet as is the taste. It is primarily used in surgery for its peaceful anesthetic and analgesic effects. The laughing gas connotation comes from the euphoric effects that inhaling the gas can have on patients. The density of N2O is 1222.8 kg m-3 for liquid and 1.8 kg m-3 as gas STP.

These three chemical compounds are similar in form but very different in their reactive effects on the human body. Each of these compounds directly or indirectly interacts with CO2, otherwise known as carbon dioxide. This chemical compound is composed of two oxygen atoms, which are bonded to a carbon atom. At regular temperatures carbon monoxide stays in gaseous form. Carbon dioxide is produced by nearly every living thing, from humans to animals to plants to the smallest of microorganisms. This production happens during respiration and plants use the CO2 during the process of photosynthesis to make sugar, which either assists in plant growth or can be re-consumed. The density of CO2 is 1,600 kg/m� as a solid and 1.98 kg/m� as a gas.

While the science is a bit tricky, these are the basic details. Comparing the density of gases is a discussion that is most likely relevant only in a scientific discussion and not surrounding the nutritional value of the popular No2 supplement from MRI.
