Nitrogen

Nitrogen gas composes 70% of the atmosphere but because it is so stable it remains a gas and unusable to plant. Bacteria have evolved that can break the N2 bond and provide nitrogen as a soluble product to the roots of plants. Once taken up by the plant the nitrogen moves through the food chain to animals etc.

The main difference between nitrogen-14 and nitrogen-13 is their atomic mass. Nitrogen-14 has 14 atomic mass units, while nitrogen-13 has 13 atomic mass units. This means nitrogen-14 has one more neutron in its nucleus compared to nitrogen-13.

Most organisms take in nitrogen from the soil in the form of nitrates and ammonia, which are produced by nitrogen-fixing bacteria. These bacteria convert nitrogen gas from the air into usable forms. Some aquatic organisms can also directly uptake nitrogen from water in the form of nitrate, nitrite, or ammonia.

Nitrogen dilutes the action of oxygen in breathing air by reducing the concentration of oxygen available for cellular respiration. This can lead to hypoxia, a condition where there is a lack of oxygen in the body tissues. This is a concern in environments with high nitrogen content, such as scuba diving, where nitrogen narcosis can occur due to the effects of increased nitrogen pressure.

Helium is a noble gas with atomic number 2 and is chemically inert. Nitrogen is a diatomic gas with atomic number 7 that is often used in various industrial applications. Mixing helium and nitrogen together can alter the physical properties of the resulting gas mixture, such as density and thermal conductivity, making it useful in specific applications like diving or certain welding processes.

Isotopes of nitrogen have the same number of protons but different numbers of neutrons, affecting their atomic mass. Nitrogen ions are charged particles of nitrogen that have either gained or lost electrons, making them either negatively or positively charged.

As a rule of thumb, the atomic mass of an element equals the number of grams of that element equals a mole. Since the atomic mass of Nitrogen is 14, there are 14 grams in one mole of Nitrogen. Next, we just have to divide 42 by 14 and we get our answer: There are 2.9988 moles in 42 grams of Nitrogen.

When nitrogen intake exceeds the body's nitrogen losses, a person is said to be in a state of positive nitrogen balance. This can occur during times of growth, pregnancy, or recovery from illness. It indicates that the body is using nitrogen to build and repair tissues.

Plants living in low-nitrogen soils can obtain nitrogen by forming symbiotic relationships with nitrogen-fixing bacteria that convert atmospheric nitrogen into a usable form for the plants. These bacteria can colonize the roots of the plants and provide them with the nitrogen they need for growth. Additionally, some plants can also take up nitrogen from organic matter in the soil or through the decomposition of dead plant and animal material.

The nitrogen balance will be negative since the person is losing more nitrogen (19g) than they are ingesting (16g), resulting in a net loss of 3g of nitrogen. A negative nitrogen balance indicates that the body is breaking down more protein than it is building, which can result in muscle loss and other negative consequences.

When nitrogen is present in a sodium fusion test, it forms sodium azide (NaN3), which upon heating decomposes into sodium, nitrogen gas, and atomic nitrogen. The atomic nitrogen emits blue light when it reacts with the oxygen in the air, giving the characteristic blue color to the flame during the sodium fusion test.

Atmospheric nitrogen is composed of two nitrogen atoms bonded together (N2), while chemical nitrogen can refer to various compounds involving nitrogen, such as ammonia (NH3) or nitrate (NO3-). The molecular weight of N2 is heavier than individual nitrogen atoms found in chemical compounds, leading to atmospheric nitrogen being heavier.

No. Sugars are composed of carbon, hydrogen, and oxygen, but not nitrogen.

Soluble nitrogen refers to nitrogen compounds in soil that can dissolve in water, making them available for plant uptake. It includes forms such as ammonium (NH4+) and nitrate (NO3-). These forms of nitrogen are important for plant growth as they are readily accessible for use by plants.

If you are told it is a fact that animals do not need nitrogen, you can infer that you are receiving incorrect information.

All living things require nitrogen. However, animals are not able to obtain the nitrogen they need directly, but must get it from their food, and that comes ultimately from the plants that are able to absorb nitrogen from the soil.

if not from the atmosphere , they must depend on a process called nitrogen fixation.

They get it from the soil. That's why farmers add fertilizer to the soil to increase nitrogen content

In the Nitrogen Cycle, a lot of Plants and depend upon nitrogen for growth. Nitrogen is needed to form amines and amino acids. These two chemical groups combine to make different proteins. The proteins are used for cell growth and repair in plants and humans.

Free nitrogen is a problem for organisms because most organisms cannot directly use nitrogen gas (N2) in the atmosphere. Instead, they require nitrogen in a usable form like nitrate or ammonium to build essential molecules like proteins and nucleic acids. Some specialized organisms, like nitrogen-fixing bacteria, can convert free nitrogen into a usable form through a process called nitrogen fixation.

Soil acts as a nitrogen reservoir by absorbing and storing nitrogen from various sources such as organic matter, fertilizer application, or atmospheric deposition. This stored nitrogen is available for uptake by plants and can be converted into different forms by soil microorganisms, contributing to nutrient cycling in the ecosystem.

There is one atom in nitrogen

there is not one atom of nitrogen, there is one molecule of nitrogen.

There is 6.02 * 10^23 atoms in 1 mole of nitrogen.

Or simply the natural state of nitrogen is n2. or two nitrogen atoms to a molecule. =]

Heterotrophs obtain nitrogen by consuming organic matter containing proteins or amino acids. They break down these complex molecules into simpler forms through digestion, allowing them to absorb and utilize nitrogen for various cellular functions.

Nitrogen RAM refers to a technology where nitrogen gas is used as the cooling medium for computer memory modules. This allows for more efficient heat dissipation compared to traditional air or liquid cooling solutions, which can potentially improve performance by allowing higher overclocking capabilities. However, it is not commonly used due to the complexity and cost associated with nitrogen cooling systems.

Yes, baseballs are typically made with a rubber or cork center, which may contain small amounts of nitrogen. Nitrogen gas can also be used to inflate the baseball to a specific pressure level for optimal performance.

When nitrogen taken into the body exceeds nitrogen losses, it is referred to as positive nitrogen balance. This usually occurs during periods of growth, recovery from illness, or when physical activity promotes muscle synthesis over breakdown.
