How can we reduce nitrogen oxides?
Process modifications include using specially designed low-NOx burners, reburning, combustion staging, gas recirculation, reduced air preheat and firing rates, water or steam injection, and low excess air (LEA) firing.
These modifications are capable of reducing NOx emissions by 50 to 80%..
Why can’t humans breathe nitrogen?
Nitrogen is an inert gas — meaning it doesn’t chemically react with other gases — and it isn’t toxic. But breathing pure nitrogen is deadly. That’s because the gas displaces oxygen in the lungs. … Rising carbon dioxide in the blood is what triggers the respiratory system to breath.
What gas kills you instantly?
Carbon monoxideCarbon monoxide, or “CO,” is an odorless, colorless gas that can kill you.
What was Rutherford’s experiment called?
Rutherford gold foil experimentThe Geiger–Marsden experiments (also called the Rutherford gold foil experiment) were a landmark series of experiments by which scientists discovered that every atom has a nucleus where all of its positive charge and most of its mass is concentrated.
What is the most toxic gas?
nitrogenBut surprisingly, amongst all the toxic, corrosive, and otherwise nasty gases that exist in industry, the most deadly of them all is the one we breathe in the most – nitrogen. Nitrogen (N2) is an inert and invisible gas that makes up about 78% (by volume) of the air we breathe.
What is nitro oxygen?
Nitrogen oxides are a group of seven gases and compounds composed of nitrogen and oxygen, sometimes collectively known as NOx gases. The two most common and hazardous oxides of nitrogen are nitric oxide and nitrogen dioxide. … Nitrogen oxides and sulfur dioxide react with substances in the atmosphere to form acid rain.
What is the formula for nitrogen and oxygen?
Description. Oxides of nitrogen are a mixture of gases that are composed of nitrogen and oxygen. Two of the most toxicologically significant compounds are nitric oxide (NO) and nitrogen dioxide (NO2). Other gases belonging to this group are nitrogen monoxide (or nitrous oxide, N2O), and nitrogen pentoxide (NO5).
What was Rutherford’s contribution?
Rutherford’s contribution was the discovery that atoms contain a positively charged nucleus much smaller than the actual atom. Rutherford was not an Oxford physicist, as stated in the article. He worked in the Cavendish Laboratory at Cambridge University.
What is the strongest poison?
Botulinum toxin1. Botulinum toxin. Scientists differ about the relative toxicities of substances, but they seem to agree that botulinum toxin, produced by anaerobic bacteria, is the most toxic substance known. Its LD50 is tiny – at most 1 nanogram per kilogram can kill a human.
What is the formula of nitrogen monoxide?
Can we breathe on Mars?
Carbon dioxide atmosphere By comparison, Mars’ atmosphere is 95 percent carbon dioxide. “We need to breathe oxygen,” said Lee. “There’s no free oxygen in the Martian atmosphere. You cannot breathe this gas.
How do you remove oxygen from nitrogen?
You can use the freeze /thaw method to remove dissolved oxygen from a solution. This is the best way to get rid of oxygen. First you freeze your reaction mixture using liquid nitrogen, then pull vacuum for few min while it is frozen.
What was Rutherford’s theory?
Ernest Rutherford is known for his pioneering studies of radioactivity and the atom. He discovered that there are two types of radiation, alpha and beta particles, coming from uranium. He found that the atom consists mostly of empty space, with its mass concentrated in a central positively charged nucleus.
What percentage of air we breathe is nitrogen?
79%Inhaled air is by volume 79% nitrogen, 20.95% oxygen and small amounts of other gases including argon, carbon dioxide, neon, helium, and hydrogen. The gas exhaled is 4% to 5% by volume of carbon dioxide, about a 100 fold increase over the inhaled amount.
Why we inhale only oxygen not nitrogen?
The short answer is that you inhale oxygen because you need oxygen for some biological processes. A fairly important one is the production of ATP, the energy all of our cells use. In the process, electrons are used and oxygen has a high affinity for electrons.
Can nitrogen replace oxygen?
Nitrogen is sometimes mistakenly considered harmless because it is nontoxic and largely inert. However, it can act as a simple asphyxiant by displacing the oxygen in air to levels below that required to support life.
How did Rutherford turn nitrogen into oxygen?
In 1919, he became the first person to transmute one element into another when he converted nitrogen into oxygen through a nuclear reaction involving the shooting of alpha particles into nitrogen gas.
What is the slowest acting poison?
It has been called the “poisoner’s poison” since it is colorless, odorless, and tasteless; its slow-acting, painful and wide-ranging symptoms are often suggestive of a host of other illnesses and conditions.
