Mass number is the total count of both protons and neutrons in an atom. This is helpful when identifying different isotopes of an element. While the number of protons remains the same for all isotopes, otherwise the atom would change elements to one with a matching number of protons, the ne...
What is the mass of nitrogen dioxide contained in a 4.32 L vessel at 48 degrees C and 1.40 atm?Ideal Gases:For simplicity of computation, we sometimes assume that the gas we are considering behaves like an ideal gas. Ideal gases behave in such a way that t...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that...

Using nitrogen, chromatographic separation of isomers and homologues can be achieved, but sensitivity is orders of magnitude less than for helium. It is reasonable to use nitrogen as a carrier gas in applications where low levels of detection are not needed, such as the characterization of samples...
To find the mass of 11.2 L of nitrogen gas (N₂) at Standard Temperature and Pressure (STP), we can follow these steps:1. Understand the relationship between volume and mass at STP: At STP (Standard Temperature and Pressur
The name nitrogène was coined by French chemist Jean-Antoine-Claude Chaptal in 1790. Read on to discover more amazing facts about nitrogen.What is Nitrogen?Definition: Nitrogen is a chemical element with an atomic symbol \({\rm{N}}\) atomic number of \(7\), and an atomic mass of \(...
What is the average atomic mass of oxygen? Oxygen: Oxygen is a very important element for animals because it is required for cellular respiration. Plants generate oxygen in the chemical reaction known as photosynthesis. Oxygen is in the second row and sixteenth column on the periodic table. ...
If the two atoms are the same element, it is called ahomonuclear diatomic molecule, such as oxygen (O2) and nitrogen (N2).Polyatomic moleculeshave more than two atoms, such as water (H2O) and carbon dioxide (CO2). Larger molecules are calledpolymersand may be made of thousands of atoms...
Nitrogen deposition also changes understory plant species composition (Bobbink et al., 2010). Very high experimental N additions have led in a few cases to tree mortality (Nohrstedt, 2001, Magill et al., 2004), but the exact cause of death was not identified. Nitrogen deposition is ...
