Ratio of nitrogen and oxygen in the air?
80% nitrogen, 20% oxygen
however it's really 79% plus some decimals of nitrogen and 21% oxygen and a little moisture.
But if the question is only looking for a basic answer, just use the top answer.
Nitrogen dioxide (NO2) consists of one nitrogen atom and two oxygen atoms, giving it a ratio of 1:2 between nitrogen and oxygen. This means that for every 1 nitrogen atom, there are 2 oxygen atoms in a molecule of nitrogen dioxide.
How do you find the ratio of neutrons to protons?
The ratio of neutrons to protons in an atom can be calculated by subtracting the atomic number (number of protons) from the atomic mass (sum of protons and neutrons) of the atom. Mathematically, ratio of neutrons to protons = (Atomic mass - Atomic number).
The ratio of carbon (C) to hydrogen (H) to oxygen (O) atoms in carbohydrates (CHO) is 1:2:1. This means that for every carbon atom, there are two hydrogen atoms and one oxygen atom present in a carbohydrate molecule.
What is the ratio of elements in a compound?
The ratio of elements in a compound is determined by the number of atoms of each element present in the compound. This ratio is represented by the chemical formula of the compound, showing the types and numbers of atoms involved in the chemical bonding.
What is the ratio of 10 over 100?
The ratio of 10 to 100 is 1:10. This means for every 10 units of something, there is 1 unit of another thing.
What is the ratio of atoms in a carbohydrate?
In a carbohydrate, the ratio of carbon (C): hydrogen (H): oxygen (O) atoms is typically 1:2:1. This general formula represents the basic structure of most carbohydrates, with examples like glucose (C6H12O6) and sucrose (C12H22O11) following this ratio.
What is the ratio of hydrogen to water in carbohydrates?
Carbohydrates have a general formula of (CH2O)n. This means that for every carbon atom (C) in a carbohydrate molecule, there are two hydrogen atoms (H) and one oxygen atom (O). The ratio of hydrogen to water in carbohydrates is 2:1.
What is the ratio of elements in CL2?
Since there is no chemical element whose symbol is L, it is not possible to make sense of the question.
What compression ratio does helium need to loose its bouyancy?
Helium loses its buoyancy when it reaches a compression ratio that increases its density to be equal to or greater than the density of air. This usually occurs at a compression ratio of around 1.7 to 2.0 times the original volume.
What is the ratio of solute to solvent called?
The ratio of solute to solvent is called concentration. It can be expressed in various ways, such as molarity, molality, or mass percent.
It is the removal of solid material and mineral content out of water by the process of filtration, desalinization, reverse osmosis and sometimes distillation. The result: Pure water.
Water is a unique chemical because it can absorb other things similar to the way a red blood cell can. It can leech minerals out of the soil. It can, in a pure state clean better than some expensive cleaners. The reason you get spots on the car or on your glasses in the dishwasher is because of the residue left over when the water evaporates. Pure water leaves no residue.
Tap water is clean, or so you think, because of the chemicals added to it. Chlorine will kill most bacteria but can make you sick. Even well water is not pure. It has higher levels of minerals in it and these can cause keloids (kidney stones) in most people who use them for long times. Some bottled waters are not as as pure as you might be led to believe. Most are nothing more than local river water run through a charcoal filter and poured into a bottle with a label on it. If you drink bottled water, make sure it reverse osmosis processed.
This removes about 99.99% of impurities.
